Great replacement!
Bought for my Honda Grom and fit perfectly. Same design and functions just as well as the previous battery. Great value for the money and I would choose this again or recommend to others for as a new battery replacement for others needing the same style battery.

Absolutely Perfect
Great price and exactly what the said it was. Also arrived when it was expected. I intend to use it for something it isn't meant for so I won't say exactly but I will say that it calls for a much larger battery but I am going to try it anyway!
