  • Affordable Battery
Style: 1 Pack
This battery fit perfectly in our used Flybar and Kidzone bumper cars that I recently bought on Facebook Marketplace. I was pleasantly surprised by how affordable it was, I expected a replacement battery to cost much more. Installation was quick, and the bumper cars are working great again. I’ll definitely be purchasing another one soon for the second set of bumper cars we have. Highly recommend! ... show more

  • Great Battery performance and fit
Style: 1 Pack
this battery was a perfect fit for my grandson's electric quad. The voltage when I opened the box was 6.19 vdc. installation was easy and the quad ran perfectly with this new battery. Amazon delivered the battery 2.5 hours after I ordered it.

  • Works fine for me.
Style: 1 Pack
Fit our older emergency light just fine. Fast delivery. Good price. As long as they are pretty cheap, I'll keep buying them every 3 or 4 years. But at some point it will make more sense to buy a modern exit light with NiCad batteries and LED bulbs instead of incandescent bulbs. The NiCad batteries last longer and aren't nearly as heavy this lead-acid type of battery. But I'm lazy and don't want to change the entire fixture. What do you do with an old emergency light? Throw it in the landfill I guess. That's wasteful. At least my local auto store will recycle this lead-acid battery. ... show more

My kids are in there middle and late teens now so the electric four-wheeler was given to my nephews little one and he rides it all the time.
