Review: GREAT charger - 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
Review: Great for a single motorcycle - 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!
