Best charger out there, its that simple.
I did a lot of research and I have used many different brands of chargers. The OptiMate series of chargers can't be beat. They are the most sophisticated and problem free chargers out there. I have a number of them and they always do the job. I have even been able to bring a couple of batteries back to life. Highly recommend this product in its many superior forms.

Very easy to use
The manual has many modes of operation but it also functions perfect for a plug and play. I have a lithium ion battery on my motorcycle and it has kept the battery healthy in periods of no use.

Kind of complicated but works
Complicated instructions when it comes to all the features but works to keep my Shorai Lithium Battery LFX36L3-BS12, properly charged.

Lithium charger worked great
Lithium charger brought back my dead Lithium battery. I had to jump it with another lithium battery to get my dead lithium battery over 12 volts but after that my dead battery took a charge and completely recharged.

Built like a tank
It did NOT save 2 dead Lithium batteries, but that's not the chargers fault, I guess they were just to far gone. The thing has some weight to it. It doesn't feel like a cheap piece of plastic junk. I am using it to maintain a lithium battery, and for that it is overpriced imo.
