12V 5.5Ah BB CPS5.5-12 Compatible Replacement Battery for UPS Devices - by UPSBatteryCenter

I use this with a Yaesu FT-818 and it seems to be about the right size (5 Ah) for QRP work. It does comewith a charger.

BB CPS5.5-12 Replacement BatteryI ordered this replacement battery for my CyberPower SX625G UPS. This IS the correct physical size for this UPS. The original battery specs is 5.5A@12V. This replacement is actually a little better because it will supply 6.5A@12V, whih means it will stay on a little longer when there is a power outage.However the photo shown is incorrect for what was received. I received a TLV1265F2F1 battery. The downside is that the ad showed the same F2 battery terminals which my original battery has. The positive terminal is okay (F2) but the negative terminal is smaller (F1). The P/N TLV1265F2F1 shows F2F1 as a suffix indicating different sized terminals. Amazon has two different web pages for this battery, both from UPS Battery Center. The one that I ordered from did not show TLV1265F2F1 in the spec. It only showed 1 review where as the other Amazon web page showed the P/N and 30 reviews. UPS Battery Center must have created a new web page but did not delete the old one.I tried squeezing the Negative F2 wire lug so it would stay snug on the F1 battery terminal but after sliding the connected battery into the case it became loose. I did not want to have a loose connection because that can create heat and possible arcing.(not good) I managed to find a F1 To F2 adapter and used it. The vendor should have supplied this with the battery beacause they know that its NOT a direct replacement for a BB CPS5.5-12 UPS battery.Other than that it appears to be a good replacement battery so I will still give it 5 Stars.See TLV1265F2F1 Photo.

I've purchased these replacement batteries before without issue. But, the last one I got does not work, period. I need to call the company to see if they can send a replacement. It's still within the use time, but it has never powered up. These are very heavy. Tight fit, tricky to get into the case and get wires attached.

Same model as my UPS needs it fit perfectly.

Easy to install. Good price.

Worked well

This battery was a perfect replacement for the one that failed in my office computer back-up battery system. When my back-up started beeping frequently, I swapped this battery out for the old one and haven't had a problem since.

Do not by this battery. After four months of operation, the battery died and could not get recharged. This is a bad reflection on the manufacturer (B.B. Battery) and Amazon for carrying it.
