Works great
Works great, longer power, and much lighter.

Used in a Flybar 6v bumper car
After replacing the battery once with the same lead acid battery that came with the bumper car the battery would run down very quickly. The bumper car has a spot for a second battery, purchased 2 of these and fashioned a battery hold down for the second battery. I hooked them up in parallel (very important). It takes longer to recharge the new set up but, the car runs for many hours before needing recharged. Do not attempt this without a good knowledge of battery's and wiring. Use 1 of these with the original configuration and the results will be better than any lead acid battery.

bad battery right out of the box!
Bought this a year ago. Spotlight battery finally gave out. Neither of these would take a charge. Total junk!! Too bad you can't give them 0 rating.

Batteries do still work. But bad quality.
I bought these for my deer feeders to power my spinners. They do work well and have been working for about 6 months or so now. But now the top of the batteries have started to come off exposing the wires and insides. They do work but the quality is not there. Will no be purchasing again. Not a good buy at all for me. Update. 6-3-2024 I am changing my review from 1 star to 4 star. Been 6 months or kinglet since purchase and they still gave me a refund. Didn’t even make me go through the hassle of returning the old ones. That’s good customer service.
