Now I never have to worry about losing my presets or having a dead battery come spring.

it works flawless, keeps battery maintained and equipt ready for action !!

Third Battery Tender that I have purchased and it works like the others two, great!

This works exactly as described, and the price is worth it when you consider how much it would cost to replace dead batteries on 4 vehicles every time they are left unused for a few weeks.

Some of my old cars have 12 yr old batteries and they work great.

I'm thinking about purchasing another 4 bank to decrease the time it takes to top off all my batteries.

When I need to top off the truck batteries (it helps keep them healthy

This kept the batteries fresh, and ready for use on the first day of trout

If your batteries are dead, you will need to put them on a charger FIRST, before the tender.

It keeps the 2 batteries on my mowers topped off and secure over the Winter months.

Kept two batteries connected all winter (my scooter battery and my mower battery) and both batteries were fully charged and ready go go in the spring

I have this model and after a few months or so, connected to a good battery, the battery is almost dead.

but whatever I'm not using for a while gets plugged up and have not had a dead battery since so it works for me

A good investment for your expensive batteries in your diesel.

Worked great on my F-250's dual batteries.

The second bank has seen different duties to: 1) Top off my other bike battery 2) Re-condition my truck battery 3) Re-condition a deeply discharged auto batteryAll have been used since with like new results.

keeps both batteries strong

I just bought some new batteries and needed to charge them up simultaneously and this charger works great

The other charger was a singe output, higher quality unit with much more power, and best of all it had a desulphating pulse mode which far exceeded this units ability to revive batteries

The batteries on both my motorcycles now are really ready to ride on a moments notice

Excellent - no more dead batteries come spring.

Works great for my pickup for charging both batteries at once.

Keeps the batteries ready to go at any time, even in the bitter cold, highly recommend.

I jumped in to one of my cars today and the battery was dead!!!!

Great battery maintainer, I have three motorcycles and a camper battery hookedtoer mine and all are fully charged with no boiling over.

I hate buying batteries.

I've lost other batteries to overcharging from inferior products

easy to use and a must purchase to protect your battery for long term storage

Nice battery tender

Nice battery tender

I also have a Battery Tender Jr.

No more going out to ride bikes only to find dead batteries!

Like others have said, don't waste your time with cheap float chargers that can wreck your expensive batteries.

I work at a car dealership in the service department and many of the technicians use the Battery Tender products on their personal vehicles (classinc cars, motorcycles, etc.) and I recommend ths product line to multiple customers

Excellent product that I believe pays fot itself in the long run as it entends the life of what have become very expensive batteries.

Awesome product, keeps the batteries in my diesel truck topped up nicely all winter while she's safely tucked away from old man winter and those dam salt trucks.

This keeps all my toys' batteries ready over the winter storage period.

These things work, I have this setup for my boat with dual bats and I never worry about dead batteries anymore

I previously would setup my various batteries in parallel and use one maintainer- better than nothing but really not a good idea and no way to keep the individual batteries healthy.

Every time I want to go out for a ride the battery is charged ready to go.

Turns out what we thought were great batteries were not worth the price we paid.

Dead battery, it will recharge it (provided you have a solid battery to begin with), low battery it will recoup it, and new toy but cant use it for a while, no worries it will maintain it

Batteries in their golf carts and leave them for 5-6 months while returning back up north for the summer..without this maintainer they would be returning to dead batteries which shortens the life of the battery dramatically and is a costly replacement

The price is decent, the setup is simple and now I am able to keep the batteries fresh in both of my motorcycles at the same time

THIS IS ONE OF THE BEST BATTERY CHARGERS ON THE MARKET

This looked like a perfect lay-up solution for two bikes but when the charger arrived it had a warning label that stated it was only compatible with lead acid batteries, not at all what the Ad said

I connected it to a mostly dead battery in my lawn tractor and it brought it up to speed without any other interference

I had been using a DIE HARD battery maintainer but was not happy with it

Never had a dead battery, thanks to this little guy!

My car and bike are each ready to drive each day without having to consider which vehicle "needs" to be driven to avoid a dead battery.

Organized and looking professional and functional to keep all our batteries ready for action.

Best Battery

I attached this to my truck battery for over 45 days and my battery still was dead, now I am stuck with a piece of trash that I cant return because itis past 30 days

It also fully charged my dead atv battery after sitting for 6 months, saved me 90 bucks immediately

Perfect for my toys as the rest in the garage no more dead batteries in the spring.... pays for itself in no time.

There's nothing worse than having to charge a dead battery on that first nice day of spring

Our regular batteries are maintained very well by the system.

The perfect battery charger/maintainer for two batteries simultaneously

Just what I needed to keep both batteries on my bikes healthy.

We had issues with the units, in the past, having dead batteries only a month after charging the batteries to exercise the units

Now I don't have to worry about buying costly batteries anymore.

Have yet to have them ruin a battery or not keep something properly maintained. very good product.

It seemed like I was buying a battery every 3-4 months for one of my vehicles or pieces of equipment

The trickle charge keeps the batteries fresh, while the charger is easily mounted on the wall, near our bikes.

Now, I just keep them on the charger all winter ad haven't lost a single battery

I put the permanent fused ring connectors on my scoots, and just keep them plugged in all year round to keep the battery nice & fresh all the time.

Every time I have went to start my motor, the batteries seem to be fully charged, thanks for a great product.

it has kept the batteries perfect.

This was my second battery tender purchase.

No battery issues ever since installing.

Before getting this my batteries would be dead when I needed them.

Since I have been using it my batteries have been perfect.

I have used Battery tender products for years.

If you use lead/acid batteries to save a few bucks, you can easily get 10 years usage out of them if you keep them conditioned with this battery tender device.

Works great, battery is always charged

I have two red top batteries in my truck, and bought this charger to keep them maintained when the truck is not being used

It is an intelligent battery maintainer, they are not the

and my batteries are always ready to go.

One of the cables was wired backwards took me a couple of days to figure out why one battery was not charging and why unit was telling me the battery was bad

Would certainly recommend this to anyone that has multiple items that need their battery kept fresh for spring.

Easily worth the price if you need to regularly maintain 4 batteries and don't appreciate turning the ignition on next season and only getting silence or that weird clicking sound.

This unit is one of those that is not intended for use with a dead battery.

The incredible battery life Is, I believe, the product of the battery tender.

This will keep batteries topped up, and even recharge slightly depleted batteries over 12-18 hours.

This finally solved all my headaches pertaining to dead batteries

I live in Alaska where the temps can be as cold as the low 30's or colder at some times and summer can be only in the mid 50's to the mid 70's with plenty of rain, I have a dual battery set up and can't always go out on the waters as I would like, but having a Battery Tender dual bank takes away a worry of dead batteries.

I think most of these electronically controlled units WILL NOT charge a dead battery, they don't know for sure that they are connected properly, so won't turn on the charging cycle

the Alligator Quick disconnects work great for the vehicleshttp://www.amazon.com/Battery-Tender-081-0069-4-Alligator-Disconnect/dp/B000ND0WB6/ref=wl_it_dp_o_pC_nS_nC?ie

Perfect for my toys as the rest in the garage no more dead batteries in the spring.... pays for itself in no time.

Either you need to pull the batteries out (annoying) or buy a pile of the 25' extension cables (what I did) to reach over to the cars

This will not charge a completely dead battery but it works awesome to keep the batteries fresh while it sitsIn the shop over the off season

I've had many batteries go bad because I don't remember to charge them every now and then during cold months

Already in use no problems keeps batteries of all types in peak performance

this thing will even resurrect a dead battery!

In fact I placed a friend's dead battery on one bank for a day and it fully charged

Easy and simple, no maintenance needed at all and all my batteries and ready to go when needed.

Dead battery, it will recharge it (provided you have a solid battery to begin with), low battery it will recoup it, and new toy but cant use it for a while, no worries it will maintain it

very good battery conditioner.

I do like Battery Tender products, though, as this is my 4th purchase

no worries about weak batteries any more.

Fried a battery or two with Schumacher which are cheaper

Awesome battery tender.

Awesome battery tender.

Due to circumstances beyond my control, I couldn't start using the tender for almost 6 months after my new battery, but now I've been using it for about 18 months, and that same battery seems fresh as a daisy.

Battery four port tender works well with the family vehicles in the garage.

Battery four port tender works well with the family vehicles in the garage.

My batteries on my bikes went dead because the last battery tender died

After reading a bit more, I wish I had purchased a device that had a desulfonator pulsing circuit built into it...that would come in handy for tough old batteries, it seems.

Have used Battery Tender products for years, always a dependable product,.. will continue to depend on these for my battery storage needs..

this battery tender will keep my riding lawn mower & walk behind bush hog's batteries fresh all winter

It would be a shame to send good batteries with lots of life left in them to the recycle plant.

so I see them easily and never damage my batteries which is the whole point of these devices

I like the green lights because you can see if the batteries a kept fresh

Battery Tender Plus 12V Battery Charger, times two

Excellent - no more dead batteries come spring.

Now I never have to worry about having a dead battery ever again

An unused, unmaintained battery dies in a very short time and are expensive to replace (deep cycle, hybrid, and starters).

No more dead / weak batteries from lack of use.

but whatever I'm not using for a while gets plugged up and have not had a dead battery since so it works for me

I have this model and after a few months or so, connected to a good battery, the battery is almost dead.

I have one connected to my toy hauler and the batteries are ready always never have to worry

If it works as well and as long as my other 3 Battery tenders I will be more than satisfied.

I have this hooked up to a quad and a sea-doo and the batteries are always ready and charged and good to go

Love this tender; keeps my motorcycle and truck batteries well charged over the winter months at the same time

Never a dead battery

The Battery Tender keeps all of the different sized batteries charged up and ready to go.

I used to replace my battery in my UTV every year and constantly had to deal with dead batteries when I went to use it.

For years I fought with weak batteries that just didn't last very long

Exactly what I was looking for, needing to charge multiple batteries and keep maintained, boats, 4-wheeler, snow mo.would highly recommend, not a cheap made item.

We are a FIRST FRC robotics team and this is the first time we've had a chance to use a better battery charger.

Let’s me keep my motorcycle and lawn mower batteries charged and ready.

Every spring we had to deal with replacing batteries, and during the summer after a few weeks of idle time we would have weak or depleted batteries

so don't be fooled with other spin off junk that will damage your expensive batteries.

and your battery will be perfect when you need it.

Best battery charger I ever bought

This will not charge a completely dead battery but it works awesome to keep the batteries fresh while it sitsIn the shop over the off season

I use this 2-back to keep the batteries for my boat charged over the winter as well as summer.

Exactly what I needed to keep both of my Harleys batteries well maintained during the winter months

I almost got the 4 battery one but opted for two 2 battery chargers so I could use one at the lake and one in the storage garage and not have to drag batteries all over the place.

Nothing works as well as Deltran's various Battery Tender products to keep a live battery in good health or revive a dead one.

my bike hasn't had a dead battery and starts right away.

I have several hobby cars that are not driven daily, so I was always having dead batteries.

So nice to be able to just plug in one plug and know all 4 batteries will be ready to go

I even have one on my truck because I am out of town for extended periods of time, 4-6 months, and this keeps the battery ready to go

With all of the LEDs burning, computer memory etc, the main battery would draw down to 11 volts or less in just a month

Keeps the batteries on my boat charged and ready to go fishing

As stated works really well keeps up batteries up for many years this is our second one and the first one still running strong keeps

The result was a dead battery which was obviously no good after the tender did not keep it charged so a useless tender and a ruined battery.

so don't expect to take a dead battery plug it on and have it charge in 15

The Battery Tender is keeping my batteries in shape and ready to work with a minimal amount of work on my part and no worry of battery damage due to overcharging.

Performs well in all seasons, all weather...keeps batteries healthy throughout cold of Northeast winter and mid-Atlantic sweltering summers ... ...

this is great, charges 4 batteries, easy to hook up.

It is great it is keeping the batteries on several of my vehicles charged and ready, well worth the purchase.

These things are amazing no more dead batteries!

Best battery charger's for our many motorcycles

Much better than dealing with a dead battery in a snowy parking lot while everyone waits for you to get things going.

No more dead battery's.

If you're like me and charging 2 or more motorcycles, buy the extension cables, what's attached to the unit is fine for two loose batteries side by side, or a few feet apart.

Pretty sure the charger thought the batteries were bad because it couldn't bring up the voltage with the stereo & amps on, so it disconnected and waited for a reset

realizing the battery is dead.

Have 4 battery's hooked up during winter and works great.

Needless to say, I purchased the battery tender product again this year.

I can have a dead battery back to full charge in under 2 days.

Two batteries are ready when needed

These things are amazing no more dead batteries!

no complaints, beats a dead battery at the worst time.

does what it says, or at least appears to tend the battery well.

However note that if you battery is dead this charger will not start charging unless it senses 3 volts (safety interlock feature to protect against loose cable ends shorting) so you will need to connect another battery or get it started with another type charger first.

and I don't have to worry about weekly trips up to the boat to switch a big clunky battery charger from battery to battery.

This is the third Battery Tender product I've purchased.

and all batteries are healthy and strong

The Battery Tender is keeping my batteries in shape and ready to work with a minimal amount of work on my part and no worry of battery damage due to overcharging.

These are great for keeping batteries fresh over the winter months.

Great Battery Tender.

Great Battery Tender.

Both batteries are always ready when they should be

My batteries love it.

Attached tender to 1 month old battery which had a Battery Tender Jr. attached and was holding it's voltage at 13.35v.

I've been using a Battery Tender Jr. for my 300cc scooter for years now

This is a life saver and $$$$ saver as well, no more new batteries every year or so.

Battery Tender

Half of the vehicles have maintenance free batteries and the others have caps so that fluid levels can be checked and adjusted

Now my equipment will be charged during the winter months and be ready to use come springwithout the hassle of charging the batteries.

I have boiled out the battery liquids on a couple of vented, smaller batteries.

I use to only be able to afford the cheap chargers but when they go out you never know and your battery is drained down and often damaged

My father also experienced a problem with another brand of maintainer overcharging his Gold Wing battery not only ruining the battery but causing its acid to spill over parts of the bike causing damage

Great multi battery charger

This has been very handy in charging both batteries simultaneously and independently on my 2011 Ford F-250.

no worries about a dead battery in the spring.

Doesn't overcharge agm batteries and they are always ready to go and batteries last longer.

and it is the famous Battery Tender -

My husband was tired of having his car failing inspection every spring when he would put it back on the road from storage because the battery was dead from either not being disconnected or just discharging all the way from sitting.

I also have had the single Battery Tender for years and will charge a dead car/truck/jeep battery in several hours.

this is a must to keep batteries maintained and ready for use.

Bought this unit to keep Antique/Classic car and truck batteries charged over winter months

When the battery is 80% charged the green LED blinks, and when the battery is fully charged and is in the "maintenance" mode, the green LED burns steady

This will not charge a completely dead battery but it works awesome to keep the batteries fresh while it sitsIn the shop over the off season

If you've ever known the feeling of a dead battery this is a "must have

My batteries are kept at ready for use as needed..

This time i burnt up a battery also

However a fully dead battery needs to get the full charging cycle

Came with everything needed, works as it should.

I have been using this charger on my boat batteries for several months now and it works exactly as they say it would.
