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..

Good product
Item shipped fast. This is my second purchase of batteries they lasted 3 years and probably would have lasted longer. But I did not check charge on them as they were aging, so that is my fault, and when I did check them the voltage was below the rechargeable voltage rating stated on battery. I am happy with their life span and will continue to use this product. I use the at my shop for the emergency exit sign that also has flood lights

Not comparable with mojo decoys (without modification)
Good battery. Had great performance. Holds charge and works great. However*. If you are using this on a mojo decoy, you will either need to use the Mojo proprietary battery. The mojo batteries have a notch cut in them and the decoys have a corresponding landing that you will need to file off/ hack at with a chisel/drill to make the battery fit (likely voiding any warranty it has available). I won’t take it out on the battery (this battery works great) but buyer beware (see photos right above the negative terminal)
