It looks like Optima does a better job with chargers than with batteries.

It's been doing a great job

It did a nice job on identifying a weak battery and slowly desulfating but would not push the battery over the top to full charge.

I have a couple of CTEK chargers that seem to do a great job not only with keeping batteries maintained, but also bringing them back

but it does a great job.

Any other cheaper battery tender will do the same job

It does a great job and worth every penny.

This revived my battery and does a great job keeping it charged during winter storage.

Optima has done a great job to make charging your battery easy and simple.

Charger does a great job and is nice and compact

Does a good job of charging up a battery

I have had a lot of other chargers and some have given me untold grief, these on the other hand to a great job

The display does a great job showing the status and current voltage of the battery.

This thing has been doing an excellent job keeping the battery up in my race car during extended down time for repairs or upgrades which is like pretty much like always because racecar

As strictly a charger, it works great and does a good job topping off and maintaining batteries

Purchased this over a year and a half ago and it is still doing a great job for my optima yellow top

This thing does a great job at charging and maintaining AGM batteries.

Great job Optima!

The Optima charger does a great job to recharge the battery without hassle.

I am back in business and it does a great job maintaining and charging the optima battery on my old boat
