Service life
FWIW I got a full five year service life out of this battery. I can say that I got my money's worth.

Great product works as described a little instructions would’ve been great
The product fits my power supply just right and I was able to figure out how to install it is not really that hard. I just think providing guidance at the very least provides reassurance that you are installing it correctly and not breaking the product or where you are installing it. I provided some guidance in my video hope it helps someone else.

Pretty much DOA
My previous UPS battery was 6 years old and the UPS started chirping it needed a replacement. Ordered this as a replacement since my 6 year old battery was also an ExpertPower and lasted. I noticed the battery looked more scuffed and scraped than my 6 year old one it was replacing. Replaced the battery and powered up the UPS and it started a continuous tone - bad battery. Took the UPS apart again and measured the voltage of the battery and it was 9.9Volts! I let the battery charge overnight (measured 13.5V going in). Measured the voltage after 10 hours of charging and it was still 9.9Volts. Packed it up to be returned.

Perfect fit.
Battery was exactly the same as the original. Installed in 10 seconds. Delivered less than 48 hours after ordering. Doesn't get any better.

This is an outstanding replacement for original APC UPS battery.
I purchased this battery SIX YEARS AGO for use in my APC 350 UPS backup supply. It still holds a charge but the APC unit is displaying a red flashing "replace battery". This unit powers my internet/wifi router and cameras. I am quite happy with the performance and the time it lasted. I'm ordering another one today. Highly recommended!
