Review: So much lighter and so far so good - 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.

### ⭐⭐⭐⭐⭐ So much lighter and so far so good

### ⭐⭐⭐⭐⭐ Replaced the 12V 9.0AH battery in my APC 900 BVN900M1
*by H***R on 10 December 2024*

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.
