Works with the flybar bumper car
I love this battery as a replacement for the flybar bumper car. It was so easy to install, and it made our bumper car run like new again. If you have littles with a 6v ride on, this is a great battery replacement.

Very pleased with product and Customer service department
Ordered a 2-pack on 12/10/25 received on 12/12/25... The first battery I tried was not working and would not hold a charge. The second battery I tried was installed (Moultrie Deer Feeder) fit and works perfectly!!! I notified customer service by email and they responded on Monday morning. Resolved the issue immediately !!! I have the feeder set up to run twice a day and after a week the battery is still going strong..

Polaris Battery
I have this battery in my Polaris, which sits for long periods of time without being started. It usually starts even after having sat for, sometimes, a couple of months.

Genial, sirvió bastante bien, la ocupe para un montable y de inmediato se notó la respuesta, vamos a ver la durabilidad pero como veo si va bien

The packaging is very well made, and the two battery showed a 6,3 volts charge at the box opening. Very good product to use with my trail cameras.
