    • Fit like the origanl
Style: 6Ah
Battery did not come charged. I had to charge overnight before it could be used. Other than that the battery performed well.

    • It’s exactly what we expected.

We needed it for an electric fence to keep small animals from burrowing under our garden shed. It works great.

    • Stated Battery Specs A TOTAL LIE
Style: 6Ah-2 PACK
What a complete disappointment! There is NOT 6Ah of power reserve in these so-called lithium-ion batteries. I bought 6 of them to replace my several-year-old lead-acid 6V batteries for my deer feeders just outside Langtry, Texas. I’m mentioning the location because of the sheer frustration I’ve had, driving 120 miles round-trip to Del Rio just to replace these brand-new, straight-out-of-the-box pieces of garbage. Out of the 6 batteries I purchased, NOT ONE functioned. They all arrived dead. I wasn’t immediately alarmed, thinking, “No big deal, I’ll charge them overnight.” After all, true lithium batteries are known for their excellent shelf life. The fact that they were all completely dead upon arrival should have been my first red flag. How much power did these so-called lithium batteries have? Just enough to spin a 6V deer feeder motor for 2 test spins. After that? Dead. Completely dead. Not even enough power to run the digital clock. I can't express how angry and ripped off I feel, especially after wasting over two hours of my day driving 120 miles in rural Texas to replace what should have been functioning products. If one battery was defective, I could chalk it up to bad luck. But six defective batteries? That’s not bad luck—that’s a serious problem with quality control. To make matters worse, I’m questioning whether these are even real lithium-ion batteries at all. To say I’m frustrated is an understatement. What a complete waste of time, money, and trust. ... show more

    • Batteries do still work. But bad quality.
Style: 6Ah-2 PACK
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. ... show more

    • Used in a Flybar 6v bumper car
Style: 6Ah-2 PACK
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. ... show more
