Reviewer: Ehowland Location: Boston Age: 45-54 Experience Level: IT Professional Owned Product: over 6 months Rating: 3/5 Not thrilled but nice options. January 15, 2017 I PHYSICALLY have 3 of this very model. I bought 2 on sale in September 2013.
I used one right away 9-28-13 (and never opened the second, for a while). It started 'beeping' and finally in February of 2015 (while still under warranty) APC sent an entire replacement unit. I put that in service 2-26-15 (I wrote dates on each battery and device). Last week the 'replacement unit' APC sent started beeping and saying the less than 2 year old battery was NG. So I got all three units (heavy!) and swapped them around (one at a time).
The 2015 (warranty unit) complained the battery was NG, the original 9-28-13 complained the battery was no good. Android browser app chrome. I plugged in the second I bought that has been sitting for years (let it charge all night) and ran the test (after swapping all over). Oye, 3.2 year old battery works, but 1.9 and 3.3 year old battery is NG? I have ordered a new battery from Amazon (about $40 APC OEM cartridge). I don't know how long this will last but the batteries are not good. NOW on the unit itself. Nice features, good software / USB integration and the ability to add the extra runtime HUGE battery pack, is a BIG feature.
