APC Replacement BK500M UPS battery [Electronics]

I ordered this battery when my FiOS battery started beeping. I first checked the Verizon web site, but recoiled at the replacement price. This battery from Amazon matched the specs perfectly at a fraction of the Verizon price, so I ordered it. It connected easily and the beeping (and red light) stopped. However, I began seeing messages on my TV screen about my battery needing replacing. It must have been a time-related message, as there were no indications of problems with the battery. After a few weeks, the messages stopped. The battery is still working just fine. I have no reason to doubt that it will last as long as the original. Maybe longer. I'm pleased. When the battery DOES need replacing again, I'll be right back on Amazon shopping for another.

Arrived quickly, works perfectly with my UPS and circle correct voltage and amperage.

It arrived fast, and I now have a working UPS that powers my cable modem, router, and VOIP transceiver when the power goes out! :D

Did a replacement for a current UPS I had. So far it has been working fine. Time will tell if any issues exist.

Product was as described. Brought my APC BK500M battery back-up unit back to life. Good price and fast delivery. Hope to get a few years more from my unit.

It got here really fast. It installed easily and seems to be working just fine. Will update if that changes.
