Power-Sonic PS-1250F2-12 Volt/5 Amp Hour Sealed Lead Acid Battery with 0.250 Fast-on Connector, one Color

My APC BE425M UPS battery died and although it says specifically on the UPS page that it is "Battery not user replaceable" It sure as heck is replaceable. And this battery fit inside perfectly, with the right sized battery terminals and dimensions. If someone with the same UPS somehow stumbles onto this, just know you need a Philips screwdriver with a REALLY long shaft. I found some youtube video guide on swapping it as well. Overall much cheaper than buying a whole replacement UPS. And I get to avoid pointless extra E-waste.

Fast shipping, as new as you can get!I've bought Power Sonic cells before and had a manufacturer date of the year prior.Order this battery from this store from a recommendation and I am beyond pleased with how well they shipped and with the current year (2025) manufacturing date.10/10 would recommend.Test the cell with a ideal (perfect) score!

Got my battery 2 days earlier then expected, it was exactly what I needed as well.

This is an exact replacement for the Lift Master series. 12v/4.5-5.0A. I did have to change the connectors to work with the batt but no biggie for a tech guy.

Have used PowerSonic batteries in the past. Always reliable and have good life span. Connection lugs were to wide for tails on alarm panel. First time I've run into that problem. Not a big deal, just did a little trimming with a pair of side cutters.

Works great

The Power-Sonic PS-1250F2-12 Volt/5 Amp Hour battery is exactly as described. I. bought one, then a second after receiving the first one and being happy.

Terminals where a little wider than previous one, had to clip lug a little works
