    • Reliable replacement battery – works great!
This battery was a perfect replacement for my YTX9-BS. It came fully charged and ready to install. The build quality feels solid, and so far, it's holding a charge very well. My motorcycle started up instantly, and I’ve had no issues since installation. Great value for the price—definitely recommend it if you're looking for a dependable lead-acid battery. ... show more

    • Started right up!
I needed a replacement battery for my Champion gas generator and this battery works perfectly. I had gotten used to having to hit the start button on the generator multiple times to get it to run but as soon as I hooked up this battery it started immediately. Thank you very much!

    • starts up every time
I loved how cheap and good quality this battery is. I needed a atv battery everywhere else was 50-100 dollars for this small battery. This battery works great and starts up my quad with no issues every time good product

    • $30, no core charge. I was worried opening the box BUT It's dry!.Didn't receive a box of acid!
Saw a ton of reviews showing bulging...soaking wet busted open acid bombs..either I just got lucky or they've upped their quality control. Tested out @ 12.94 out of the box on my volt meter. Threw it on the trickle 1.75a charger/maintainer I also bought on here for $12(Nexpow) look em up..bada$$. Saved 3 batteries so far with repair function, anyhow I digress... 30 seconds on there and it said full. So no lies, no frills, no mess. Will update when I know how long it lasts and if it'll even crank the old vtwin honda shadow I'm picking up for $500 tomorrow. ... show more

    • Battery is defective
When I first got the battery, it worked fine and now it will not hold the charge, there is nothing drawing from it because it’s hooked up to a battery switched that disconnects the battery from everything. I tried charging it a couple of times it holds a charge for a couple of days and goes dead. I believe the battery is defective. I want to send it back. ... show more

    • good product. reasonably priced !
got the battery little box in a big box with a small piece of paper stuffed in the big box that failed miserably from keeping the small box from rattling around...Typical Amazon packaging ! but it arrived unharmed i put the battery on a 2Amp charger for 24hrs and put it in the bike...and it started the reluctant machine just fine. good product. reasonably priced ! ... show more
