Used to replace back up battery for Chamberlain garage door opener in Chicago. Bought and installed late April 2023. Still working strong (now Jan 2025). Will update when needs be replaced. Reluctant at first since different technology and material. Easy to install.

I use this for extra LED lights in an enclosed trailer. It’s working great so far.

Super light batteries, less than half the weight of the originals! I guess you get what you pay for. Bought these in July 2023 - dead (not taking charge by mid-Oct 2023. Of course too late to return.. I hope the seller would reach out.

Replaced the lead acid battery in my 15kw portable generator. Man, that is so yesterday and the sucker leaked acid all over the metal battery box. This works like a charm, supposed to last 10 years, and weighs less than half as much. If you buy a lipo battery be sure to get the right charger to keep it topped up!

Exactly what I was looking for

I forgot to test this one before I started using it. It has worked well on my test bench and also charges fine. I have cycled it a few times now and it appears to charge and discharge fine. Nothing stands out about it and I have had no issues with it.RATING SYSTEM:• 1 – bad, do not recommend, and very below average in quality or function.

perfect to replace the lead acid battery in 30yr old security lighting in our youth center gym. normally they last 4-5yrs so I am hoping this one doubles that, but I've only had them for a few months so far. They last longer than the old style batteries.

The media could not be loaded. deeeeeeefinitely thought this was a regular sized battery, and that's one hundred percent my bad! not sure what i was thinking, especially at this price point. still, this is a lithium ion 12vbattery that is good for *something* even if not the application i had in mind. my solar setup is still coming along, but once it settles, this will be an added component. it's more for portable panels and small charges, like lights and phones, but i fully plan to keep this as a backup battery for the camper. the video clip shows the terminals, they look like tiny seat belts, going to need to find proper adapters before being able to connect this battery to any charging source. it's important not to overcharge or overheat, so i will need to possibly connect this to its own charge controller once the more portable set up is detailed. all i know is, living full time on the road, this little sucker is gonna come in handy one way or another!
