### ⭐⭐⭐⭐⭐ Great battery

### ⭐ Doesn't last!
*by S***N on September 6, 2025*

Bought for size and cca. I was excited when I got it installed and it started my bike. It started a total of 3 times. The third time I rode it for about 10 minutes. Pulled back in the garage and waited until the next day. Went out to go for a ride and nothing. The headlight was very dim. Wouldn't even try to turn over. Pulled the battery out, put on lifepo trickle charger for the day. That evening I tried again with no luck. Checked with battery tester. It had 13.2 volts, but no amps. The tester went all the way to "0".
