If the charging leads were longer than the six foot ones supplied, I would have mounted it inside the boat for even easier charging.

Originally I wanted a portable unit that I could clip and unclip from the boat batteries as needed (which would not be very often as the engines usually provide sufficient charge), but a permanent charger seemed much simpler

Doesn't matter if there is one trimmer or two, the charge keeps the batteries strong.

Had it on my boat for awhile and it seem to keep the charges up as promised

I have had the same issue with this product boiling all the water out of the batteries and then it keeps charging until the batteries are ruined.

You can find cheaper charges, but eventually that savings will be lost on more frequent battery change-outs, or worse, battery failure out on the lake.

I fish at an all electric lake so having a good charge is very important

I want to have the sue of 12 volt power during extended smart charging

It didn't even get noticeably warm charging my car battery

I compared the specifications of this smart charger and called Optima and Universal Battery to make sure their float charge specs as well as rapid charge specs match and they do

They have been heavily used several times but they still hold a good charge

My old battery charger uses a 12 Amp fast charge setting, 2 Amp trickle charge setting or a 75 Amp "for engine starting" setting.

With the same batteries, the new charger tops them off, after an hour of using the trolling motor on and off, I'm still showing full charge

Solid red lights when charging.

Two of the banks quit charging, what a waste of money

Perfect charging device for my boats three batteries.

The unit itself is a little heavy and can get hot when charging but stays pretty cool when tending.

Because of its smart charging circuits, I don't have to worry about over charging my battery

with this it charges each battery indapendently so each battery gets the charge to keep it up and ready for a day on the lake.

Great charging system

16 lbs. of fast easy charging.

This product works great charges my 2 batteries on my boat very well

In short, I love that it has smart charging and works well

Very happy , charged both battery's in about 12 hrs

We have a lawn mower with a battery that is on its last leg, the little charger did the job, gave the battery a good, full charge and was very easy to use.

Compact design, easy to install and fast charging.

I have it installed in my boat and leaves a good charge on my batteries

The 1st cell charger then started to register fully charged, but that would happen within 2 minutes of hooking it up to a dead, half charged, or fully charged battery.

An excellent charging system

Overall: 2/5 stars, I prefer my waterproof Battery Tender since both charge at 0.8A anyhow

Solid green lights when charged.

31 size batteries is that they are not providing enough amps for adequate charging

It's not a speed charger or one boasting super powers, but it seems to put in a solid slow charge that's good for your battery.

I don’t mind the slow charge

It's not a speed charger or one boasting super powers, but it seems to put in a solid slow charge that's good for your battery.

It easily slow charges my deep cycle marine battery on my Jon boat then keeps a maintenance charge on it over the winter.

Works great, charged batteries to their max

If a gel battery is charged at 14.4, it will quickly become damaged, as per the East Penn Technical Manual, which is available through this review page on deep cycle battery chargers:[

Its fast charging and easy to connect

Works great, fast charge for all 3 batteries

Long story short, due to my past job experience, I am very familiar with the latest correct method of charging lead acid batteries

works as it should, seems well built and heavy.

Works as it should and customer service is among the best I have every talked to.

It works as it should as of this time and is simple to install..
