  • TOBBI 6-Volt Car Back Running.
This got our son’s TOBBI 6-Volt Kids Ride On Car Electric VW Beetle back up and running. We needed a charger specifically designed for this battery type, and once we had the right setup, everything worked as expected. The battery lasts longer than the old lead-acid one and supports more charging cycles with the newer technology. It’s been running the car well with no issues so far, and I will update this review if anything changes! ... show more

  • Works on Kidzone bumper car
My son's bumper car stopped working. The original battery would not charge. Even if I used different chargers. I decided to try this battery, and good thing that it works. Right size, fits perfectly. All I had to do was use a hot glue gun to keep the wires from moving. That's how the original cable was from factory, glued on the negative post. Would recommend for any parents experiencing their kids bumper car that won't charge. ... show more

  • Not happy
No good. Lasted one charge

  • Does not hold a charge very long.
I bought this for my deer feeder to replace one of the old style heavy 6-volt batteries that had died after years of use. This battery while inexpensive, does not hold a charge very long compared to the old battery. The old one would last a couple of months or more before needing charge, this one is about a month. I am not too happy about it, but for the price, I chalked it up to you get what you pay for. I will be more selective next time. Overall, for the price it is not a bad battery, and it weighs just a few ounces. ... show more

  • Lighter replacement for camping lantern battery
Battery in camping lantern wasn't charging anymore. Concerned primarily with getting a replacement battery with dimensions same as the old battery as the placement of battery in the lantern is a tight fit; a few extra millimiters will not allow the battery to sit properly or allow the cover to be screwed back on. Overall, this battery is a good value product. It charged quickly and retained the charge. It is also so much lighter than the old battery! ... show more

  • Lithium Is Better
Why did you pick this product vs others?: I have bought this battery before my meat scale and this thing stays charged longer. This Lithium battery is so much lighter too. I'm ordering this one for a deer feeder.
