Genuine SP12-3.5 (T1) SLA AGM 12V 3.5Ah F1 Battery

Received a sealed battery that mas made over 13 months ago. I charged it , and it's holding close to 12.4V after a few hours after charging. This one will probably be OK for my small home office UPS backup, but would have preferred one that was fresher. Instead of lasting 3-5 years, now expecting 2-4 years.

The battery arrived on time and met the description noted on Amazon. So far the battery works just fine in a CyberPower CP425SLG UPS, it was not the exact OEM dimensions and the CyperPower case had to be modified to accept the larger battery. Could not find the OEM sized battery on Amazon, but it could be found on other suppliers Websites, but it had to be purchased in large quantities.

I liked it because it did what it was supposed to do. It charged up and held a charge.

it's a battery

Battery was as described and fit perfectly. Fast shipping.

Battery works great. Thanks for the quick delivery.

as advertised, charged up quickly and went straight to work in my PC backup.. good price, too
