TecMATE Optimate 1 VoltMATIC, TM-401a, Bronze Series: 4-Step 6V / 12V (0.6A), Battery Charger & maintainer,Blue

This product was recommended to me by our ATV dealer after I had had problems with cheaper versions not lasting we live in MN on a farm our ATVs run everyday no matter the weather and we need them to start we have now gone to just having them on wheelers to putting one on our back up skid loader and I charge my riding lawn mower throughout the winter. The current one I use on my 4 wheeler is over a year old-will not consider any other trickle chargers

Easy to use as you only have to plug it without any adjustments. I purchased it to replace Moco Genius 1 that failed within the first year of use. I use it on my motorcycle. Optimate seems very reliable. The plug is very stiff, my only complaint.

I purchased this for my girlfriend after she let her BMW die over the winter. The battery was so dead that it literally would not charge at all and faulted out my standard battery charger. This ran a deep repair cycle and her battery actually came back and is as strong as ever. Optimate quality at its best!

Can't go wrong with OptiMate 1 Previous one saved my battery for 10 years! Now I sold the bike and give it to the new owner. This one I bought for my brand new bike and already installed it - working as expected!

Great for use on my ATV and deep cycle batteries. Seems to give a better charge
