    Not sure if I received a bad battery. I made sure I charged it twice in the offseason of not riding and went to hop on my bike the other day it was stone cold dead. I tried to charge it and it won't even take a charge. Only had one season.

    Most expensive battery I've ever bought and on a 74 yr old Vietnam Vet budget it turned out to be junk. First couple times the Sporty started up first time. Has been kept on lithium charger Went to ride and the battery just won't turn it fast enough to start Will not buy again. Purchased August 2022 Could have bought 2 good batteries for the price i paid for this. read more.

    • Thank you for your comment. My original battery on my 2022 Fat Bob did not last the first season! The dealer at Cool Springs, Moonshine Harley-Davidson refuse to replace it within the 6 months of the purchase of the new bike. I've only put 750 mi on it.

    Costs twice as much and doesn’t hold a charge. The whole purpose of a battery is to hold a charge, so save your time, money,
