  • DEAD AFTER A MONTH!!!
Size: 5L-BS-CCA 120
DO NOT BUY THIS BATTERY!!! I should've listened to the other reviews. The battery was great at first, lightweight, started the bike strong, but then just over a month later it's totally dead. Won't hold a charge, won't charge back up. Absolute $80 paperweight. And of course I was outside of the return window so I'm out that money. SAVE YOUR MONEY AND TIME AND LOOK ELSEWHERE!!! ... show more

  • Always Works
Size: 5L-BS-CCA 120
I've had this battery nearly 5 years. It works today like the day I installed. I run my Grom very little and when I do, it just for a few minutes so I suppose the battery easily charges very fast. It has never failed me.

  • Very impressive little battery
Size: 5L-BS-CCA 120
I'm extremely impressed. I got this for my son's little pit bike but it seized up so it sat in my garage for a few weeks. Yesterday I t h e battery in my bike died and I was in a jam so I put the battery it and it performed flawlessly. What is impressive is my bike is a 1999 Buell S3 thunderbolt. 3 stars for longevity cause I have no clue how long it will last. ... show more
