12V 7Ah LiFePO4 Battery

Works well in replacing batteries in UPS.

I just replaced the battery in my APC Uninterruptible Power Supply (constant tone noise every so often). After a little research, I bought this one because of the specs and tolerances. The BMS in this battery has a 15.0A recommended continuous discharge compared to other batteries with only 10.0A. This will prevent shutdowns from PCs that need the extra umph during gaming. The size is exactly the same as the battery I removed, and a lot lighter. This was an easy swap and I'm thrilled with my purchase because of the LiFePO4 technology. Great upgrade instead of buying a new UPS.

replaced my kids toy ride with this. worked well for the first 5 chargers then 0v. life too short UPDATE: I was reached out by the customer service and they have resolved my issue with a new battery. so far its been on week 3 and still going strong after charge. great customer service.

Excelent products fixed the apc ups perfect

The reviews were great and I was excited to receive these batteries. I was convinced these were exactly what I needed for my deer feeders. I have always used lead acid batteries in my feeders and just pull them to recharge every few months when they drop in voltage too much. I don't have them hooked up to a recharging system of any kind. These worked great for about 2.5 months for one and 3 months for the other. In both cases, they had enough voltage to operate the timer and feeder normally and then died quickly to literally ZERO volts. The second one I ran a test throw on the timer, the feeder threw at full power, then the screen went blank. I pulled the battery and confirmed voltage was ZERO just like the first one. I spent about 2 weeks to try and get to take a charge and they will not. I then called Amazon and was told there was a 1 year warranty but I have passed the 30 day return deadline. No problem, they actually gave me contact emails to reach out to HWE. Their website contact info is 100% Chinese contacts and my attempts to contact them didn't work. So, I assumed that Amazon's contact emails would work but they just went into a black hole. No response at all after multiple attempts. My assumption is that if these batteries are recharged full time like in a UPS or something that maybe they are fine, but even UPS can fully drain a battery when power goes out. Be aware that these batteries have internal circuitry that literally kill it to ZERO volts if it gets drained too much and there is no bringing it back. Please note that there is no functional warranty either. I wouldn't purchase these again for any reason.

This IS a replacement for DJW12-4.5 but only when you use the F2 to F1 adapter. The User Manual is not good, so I missed that step. When it didn’t work in my garage door opener, I started repacking it to return and that’s when I discovered the adapters. 30 seconds later it was successfully installed.

Great battery, a charge last for a very long time. I use it on my HF radio.

Put this into a UPS where the old lead acid battery failed. Good fit/size, plugged right in with almost 3x the wattHours. It was only a few bucks more than lead acid with 2-3x the run time.

Actually has the claimed capacity and being used to replace lead acid SLAs that were only lasting about 18 months on bilge pump duty. Only issue is the BMS which protects the batteries but once when I allowed it to run flat shut off and my smart charger wouldn't recharge it. I connnected it briefly to a 12V car battery then tried charging again and it worked and still had original capacity. About twice price of SLAs but hoping for much longer life.

El artículo solo me funcionó en una ocasión y después solo fallo y nunca funcionó como debería, lo usé como 15 minutos. Quiero saber si me pueden hacer devolución

Compre una a principios de Marzo 2025, la conecte a mi no break donde solo my stick PC, modem y 39 inc TV estan conectadas y me duro solo 1 dia y una noche. La desconecte de la fuente electrica y sorprendentemente duro mas de una hora esta pequeña bateria dandole energia a estas tres cosas y la reconecte antes de que se acabara pero al otro dia ya se murio completamente ahora no acepta carga ni nada esta completamente muerta no se que hacer por que no la puedo devolver y que me envien otra. En realidad muy buena bateria pero la mia creo benia dañada.
