Battery Mart 12 Volt, 7 Ah Sealed Lead Acid Battery with F2 Terminals

• Model: sla7-12/T25
• Sealed Lead Acid Sealed Lead Acid Battery For 12 Volts / 7 Ah

Update 1 year later: My FIOS BBU is beeping again, indicating that the backup battery is not holding a charge. This battery lasted less than a year but only has a 90-day warranty, so I'll be looking elsewhere for a replacement.

(original 5-star review below:)

This is an exact replacement for the original FIOS BBU battery, but at about 2/3 the price of others I've seen. Switching the batteries takes 5 minutes or less and can be done without turning off the power or the FIOS router. If your FIOS BBU is beeping, this is the cure!

Like many people in our neighborhood, our Verizon Fios back-up power unit battery went dead after about 3 years. This battery works as a replacement, and we've had solid results so far after about 3 months of continuous use.

This battery was dead on arrival. Seriously. Dead as a doornail. Would not buy this again and would not order from the merchant again. I should have spent the time to get a return, but I just never got around to it. You can get *charged* units like this from your local Radio Shack, I've discovered... AND, if you are using this to replace your Verizon FIOS unit, try calling Verizon first. They came out and replaced mine for FREE.
