Belkin Universal UPS 1200 VA Emergency Battery Backup with AVR (F6C120-UNV)

 (12 customer reviews)

I just replaced the two 12V batteries on my F6C120-UNV. I had the UPS for 3 years to the day when it failed to hold a charge. The Belkin web site and some of the reviewers would lead you to believe that the batteries are not replaceable. A quick web search will show you that this 1200VA UPS uses the same batteries as the same generation 800VA and 1000VA Belkin products. It also uses the APC Replacement Battery Cartridge #17 (RBC17) that you can find on Amazon or elsewhere for between $40 and $60 for both bateries delivered. The original Belkin batteries are two 12V 7.2AH sealed lead batteries manufactured by BB. The RPC17 is two 12V 9AH sealed lead batteries made by American Battery Company. They are acutally an upgrade and will make your 1200VA UPS perform like a 1500VA UPS.

The replacement took me about 15 minutes and was about as complicated as adding a new hard drive to your PC. Remove the case -- 5 screws. Remove the circuit card -- 4 screws and 2 modular connectors...Read more

I received the Belkin F6C120-UNV as a gift in December, 2002. It worked like a charm for 1-1/2 years. I occasionally put it through a deep-cycle test just to make sure things were in good shape and my system and monitor and peripherals would run for about 20 minutes before running out of juice.. ..plenty of time to clean up, save, print a few things, and shut down the system.

I even had my wireless access point and cable modem connected, so I would stay online for a while without power in the house (through my desktop or wireless notebook).

The only annoying behavior was that the unit will beep when you are running on battery power and there's no way to configure it not to beep. That means if you lose power during the middle of the night for a more than a couple seconds, it will beep until you tell it to stop beeping. Very annoying. Luckily we only lose power about 3-4 times a year.

The bad news; we lost power last week and the unit shut off in...Read more

I bought two of these Belkins 2 and 4 years ago and both died in the last 6 months with no warning. Poof. One day they just wouldn't power on and were completely unresponsive. After reading the reviews here I bought a pair of APC batteries to try and both UPS were brought back to life. If it costs less to ship than to buy another pair of batteries I'll get the newer one fixed under warranty.

It's simply stupid that Belkin doesn't sell the replacement battery packs. Replacement is straightforward...You need a long, skinny philips-head driver to get the battery bracket out (in addition to a 5/16 driver with a long extension).

0) Unplug it!

1) Remove the 5 screws holding the cover, pull it back enough to disconnect one of the battery terminals, then remove it completely.

2) Disconnect the large 5-pin connector from the circuit board on the opposite side from the battery connectors (you have to squeeze both sides and pull on it) I used a...Read more
