12V 6Ah Mini Lithium LiFePO4 Deep Cycle Battery, 4000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Lighting, UPS, Power Wheels, Fish Finder, RV, Ride-on Toy, Camping, Built-in BMS

Love this battery. Lightweight and powerful.

Fixed a Cyberpower 750VA UPS. Working as it should. Recommend.

This is a great replacement for my Craftsman garage door opener that had an old lead acid battery that was 14 years old. I had to modify one of the terminals to make it fit the connector I had, but no big deal. It charged right up and has worked perfectly ever since. It weighs a fraction of the lead acid battery and has about double the energy density.

I used two of these to replace the lead-acid batteries in a ceiling track hoist for a disabled person. The old batteries were about four years old, and the typical "alarm system" lead-acid type. These LiFePO4 batteries have the built in charge controller, so I knew it would just be a straight across swap. My hope was to have more battery capacity than the old ones so we could go longer between charges. The experience of changing battery tech was more than expected. These things have about four times the life of the old style battery. They hold voltage high during the discharge cycle, so the power level of the motor remains consistent throughout the use cycle. That means the motor is performing near peak power until right before a charge is needed. Since these batteries weigh less than the old ones, the lift is easier to pull along the track when unloaded. All good stuff. The only concern that I've got is that the charge percentage displayed by the lift's electronics is calibrated for the lead-acid discharge curve. These will read at a high level (80%-100% charge) until they're ready to die. Once you see a 70% on the screen, you've only got a few more seconds of power before it absolutely needs to charge. That's not going to cost this a star, as it's a function of the changing the battery tech that the electronics weren't built to understand.

This is a perfect size battery for my project. It's compact, light and powerful.

Worked great. Used to repower a 12v dirt bike for a 5 year old. Holds a charge long enough to ride for 45 minutes or so. Recharges well.

It seems like these batteries are a crap shoot if you get ones that work. Bought 2 last year and they are great. Bought two this year and not so good. Came fully charged, used once, and now they will not take a charge.

Purchased this to replace a a lead seal alarm battery… It’s supposed to last twice as long so we will see because just installed it . The only problem was terminal connection which showed on site to be F1 connection was actually F2 … Not a deal breaker because had F2 to F1 adapter … if it lasts even one year longer for the price would be worth it because hail amps are higher which is a good thing.. lighter than old battery same size … Will buy again if needed .

They fit perfectly in my Emerson UPS, and have been functioning great so far. My UPS requires 4 in series (48V), which has always made replacement expensive. These didn't cost too much more than lead acid, and they're so much lighter. Hopefully they last a long time!

I bought this to replace the 4 Ah battery I lost. So far it's great for running my Ham Radio stuff, and I can charge it with an AC trickle charger or solar panel.

too early to rate performance. it's a summer item for me with a solar grid

I used this to run a bathroom light and fan at a cottage while being charged by a solar, all summer. It worked well until the end of the summer and then the system stopped working. I thought it was the battery but testing it proved it still worked and delivered a full 6 ah. It was my charging system that had failed, not the battery.

Fits perfectly in Cyberpower 650va ups. plugged in and worked instantly. Dimensions given were accurate.
