    Just after I bought this I had a hiccup one day starting it but then it started up. Brushed it off as an anomaly. Less than 2 years after purchase it is now dead as a door nail. Nothing comes on. I got bamboozled into buying this lithium battery because the guy said if it ever goes dead harley will give me a brand new one. So I said for that price it's worth it then. Now the dealer claims only a 1 year warranty and in the book that came with the HARLEY battery it is a 5 year limited warranty. Only real limit is you personally had to purchase it. Miss. my AGM battery and will never buy another overpriced harley battery when you can get more AH's and way more CCA's than a harley battery for $200. Even another harley dealer said the lithium batteries are crap and they would never sell them at their dealership. Wish I went there originally. Harley you need to be better than this! read more.

    Easy to install, amazingly light. I just put it in, and the bike started right up. It's late Feb here and to cold to ride. I hope it stands up well.

    I bought one for the weight reduction. Three months went by no problems, then went start bike and battery die . Put my old acid battery In bike started fine . Week later tryed lithium and it lasted three start ups went dead . I mean there’s no power to bike at all . Took Harley shop had tested they say it good . Even though I’m not only one had this problem. Took tried it again bout 3 start ups went dead . Tested it with test meter it will show 12.9 volts but will not power bike on . When they test it at Harley shop as long as it shows voltage rite they say it’s good and want exchange it . Twice I’ve been stuck and had have my old acid battery brought to me . I can trust it get me home Guess I’m stuck with 350 dollar mistake. read more.

    • Did the Harley shop check your stator? Sound to me like your bikes charging system is not putting out enough charge.

    The original battery in my 2020 CVO Street Glide was getting tired. So upgraded to this Lithium battery. WOW! The weight reduction too! I've installed Lithium batteries in my other bikes also. Great cranking power. Long lasting too! Thanks to the crew at Chunky River Harley-Davidson for their excellent service! The BEST1 read more.

    What is the warranty on this battery. I purchased on about 3 to 4 years ago. Now the bike is indicating “low battery”. Could that be due to the temps?
