I bought 2 batteries from this company, one was the wrong size and they wanted to charge ME for their mistake. I returned that battery on their dime and they sent me another that fit but was about $30.00 higher in price. I used the battery in the latter part of last summer (bought in July of 2018) and it worked ok but never started the bike in a strong way, I then removed the battery from my motorcycle and put it on a brand new trickle charger for the winter. I put it back in the bike in spring and it would start it in a VERY weak way. If I didn't ride it in a day or so it would be dead. I tried everything but it just wouldn't hold a charge? I took my 6 year old battery (last battery I had) out of storage and put it on the trickle charger and the bike starts STRONG and holds a charge for a long time, I contacted the company and told them everything I just mentioned and they sent me a labor intensive list of things to do and test (and you need special equipment) It was ridiculous. They'll NEVER get a dime from me ever again but now i'm out the $ I spent on this piece of junk. Don't buy from this company. Very inferior batteries..
