Noco Genius 3 1/2-amp Smart Charger is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Had wanted to get a smart charger for awhile. The manufacturer's warranty on this is impressive. Registering my 5 year warranty at their site, I was surprised to see all of the optional connector accessories and their range of other models. Looks like a real quality product! I'd say the Guide carried just the right model for my needs. Have only used it once, but it seems to work great. This was an unbeatable deal!

Rated 5 out of 5 by from Bought this to revive my small 12v lawn tractor battery, did a very good job, holds a charge now. Will use it on the car batteries to keep them in good condition. Tried using it on old car battery, it said it was beyond help, kept clicking on and off per instructions.

Rated 5 out of 5 by from Purchased primarily for RV battery. RV shops recommend a maintainer-type charger, rather than the in-unit trickle charger for maximum battery life. Most are very pricey, but this one was reasonable enough to try. It seems to work just dandy. I tried it on my old boat battery, and it seems to have restored it substantially.

Rated 5 out of 5 by from The G3500 Noco charger performed as advertised. I was unaware that the spiral wound batteries like Optima require a different conditioning cycle. This unit handled the charge perfectly and then entered the maintenance monitoring mode to trickle charge only when needed. Great product.
