Amazon.com put many APC products including Genuine APC Replacement Batteries on sale. I discovered that I needed a replacement battery the other day when the power at the Home Office sagged for a moment. All of the computer equipment in the basement including my Linux development server, VoIP Telephone Adapters, DSL modem, firewall, network switch, wireless access point, and phone system spontaneously restarted.

When I saw this I said, "I must need a new battery, but why hasn't the UPS been beeping at me?" I ordered a replacement battery the next day. That night at 1:30am, I woke up because I heard the UPS alarm beeping in the basement.

If you run your home or work phone service using Voice over Internet Protocol, make sure you have a UPS providing power to your DSL modem and VoIP Telephone Adapters. If you already have a UPS, make sure your battery is good.

I like to buy Genuine APC Replacement Batteries for two reasons:

1. Genuine APC Replacement Batteries preserve any applicable warranty coverage.
2. APC sends a shipping label with Genuine APC Replacement Batteries so you can send the spent battery back for proper disposal.
