Review: 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!
Review: 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!

### ⭐⭐⭐⭐⭐ REPLACEMENT BATTERIES
*by J***T on November 4, 2024*

I bought a farm that had a TSC DEER FEEDER, However the battery was dead. I looked on the TSC website for a replacement. They wanted $40 for a replacement battery. I ended up with 2 batteries here on Amazon for half the price and they charged quickly and are doing a great job I highly recommend these batteries. Great purchase and great quality!!
