Power-Sonic Rechargeable Sealed Lead Acid Battery PS-1270 12V 7.0 AH @ 20-hr. 12V 6.5 AH @ 10-hr

I use PowerSonic for aver 20 years! Worry free batteries! I highly recommend using them!

I was a little skeptical after reading some reviews on some of this seller's (eComElectronics) products. Several folks have complained of receiving a replacement battery that was not the item described (or they didn't read the description carefully).I carefully reviewed replacement batteries for my APC Backups ES 500VA (BE500U) unit and found out that many folks have ordered batteries from many different sellers (including eComElectronics) and then found out that the terminal size was incorrect. I have used Power Sonic batteries in the past, and have found them to be top notch in quality and longevity, and was specifically looking for this battery. eComElectronics had the very best price on this battery, and it is the exact replacement for any APC unit that uses the RBC2 (APC Replacement Battery Cartridge #2) in specs and dimensions. The terminal size (F2 - also called T2) is 1/4" wide and is the issue when many buy batteries for replacing the APC RBC2. The most popular battery sold on Amazon for replacement of the RBC2 is the UB1270 battery, and it does NOT have F2 terminals (it has F1 terminals that are smaller). Many complaints are because of loose fitting connections between the battery terminals and the battery cables. The difference in the size of the terminals is the reason (F1 vs. F2) for this. If you want a top quality battery that replaces the APC RBC2 battery, you can feel confident that eComElectronics will ship this exact battery, and it will fit and work perfect in any APC device that uses the RBC2.The price can't be beat and shipping was lightning fast.I will definitely be using eComElectronics for future purchases of my UPS battery needs.Be sure to read the descriptions of their batteries very carefully, and make sure you know what you need before ordering. Some of the batteries they sell are, in fact, replacement batteries for the items pictured (as noted in the written descriptions), not the battery pictured. This is NOT the case with this item.

Fit perfectly, came fully charged, arrived early, and better than OEM!

Battery failed after 7 weeks of use but customers service sent out a new one quickly. Have had good service life with Powersonic batteries in the past.

I have purchased several of these batteries for use in desktop UPS units. They have been as long-lasting as the original batteries and quite a lot cheaper. Just be sure you get the correct terminal size.

OEM battery to expensive. We'll see how long this one lasts. So far so good

Exact replacement of the one in my system. Easy to do job. No puzzles to solve.

Exactly what I needed for my battery UPS. Seems to be holding up pretty well.
