OptiMATE 1 Global, TM-401, 4-step 12V 0.6A Battery charger-maintainer

Good product, the battery pigtail could be longer with a hold down on the plug end All in all satisfied

Just good to have around. Works well for the batteries I've used it on. Had it about 4 years now and it works.

Arrived earlier than expected. Literally a simple plug and play into my motorcycle that the dealer installed an accessory plug in wire adapter that had a Optimate1.com sticker on it. Looked it up, read the great reviews about extending battery life for motorcycles and plugged it in and it simply did tge rest on it’s own. There are colored LED light indicators that tell you if battery is low, charging or full. When all lights are green you know it’s full and Optimate 1 will maintain the full charge. Wish everything I order for my bike was this simple. Great value for price too.

It works on my Yamaha generator EF 6300 isde battery , my other charger just stayed charging and hot . This one charged overnight then went on maintenance. So now I can maintain my emergency generator battery so with a little luck I might actually have it when I need it ? Lol

Good for maintaining batteries that are or aren't used often, the automatic mode is great as it takes the guesswork out of it all. I keep this on my ATV and it keeps the battery in float mode which is 13.5V. I believe this puts out 0.6 amps which is plenty for a trickle charge.
