This was a battery replacement for an older UPS. Battery came fully charged and fit perfectly in the unit. The battery was half the price of replacing with a new comparable UPS. Everything working fine now.

I have several CyberPower 1500AVR uninterruptible power supplies. I was confused initially what SLA battery was needed as CyberPower1500 use two batteries in series. In three UPS, they had three different battery configurations, two of which made it look like they had a special 24V battery, but, it turned out that is was two batteries joined together by a plastic insert that hid how the terminal of the two batteries were joined together. Fortunately, one of the three UPS showed the basic batteries, then I tore apart the other two and Voila! they all used the same battery.

Bought two of these to replace my UPS batteries which had died. They fit perfectly and UPS has been back up and running normally ever since with no issues.

I bought a branded APCRBC124 battery for my UPS in November 2018. It finally died. Of course the battery that I paid $48 for 5 years ago is now double that. I checked out the specifications for this battery and they seem like they are superior to the other name brand. I think that the "High Rate" battery will last longer...I hope. It takes 2 of these to replace an APCRBC124 battery. It's still cheaper than the APC brand. First, mark the red and green label sides on the center piece between the 2 batteries. Use a hairdryer to remove the labels. Once the labels are off, remove the connectors from the F2 terminals. Reassemble the new batteries to the center piece. Now comes the fun part; trying to keep everything straight and aligned to put the old labels back on which is what holds the battery together. I layed each battery on a separate piece of scrap plywood. This allows the center notch to extend below and makes it flat. I then used a 12" bar clamp on the side of the battery to hold the battery together while I reapplied the labels. I've laid out the process for you so that you won't have to try to figure out the best way to replace these batteries. Good luck.

Installed a new Interstate Battery 12V 9Ah to my APC UPS. It kept beeping which indicated a fault, overload, or a failed/dead battery. Switched back to the 5 year old battery and no more beep. Charged the Interstate battery to 12.9V using a 1 A charger. Reinstalled again and my APC UPS beeped continuously. Uninstalled and Switched back to the old battery. Update 2/16/2026 Installed a new Mighty Max Battery ML9-12 - 12 Volt 9 AH. No beep. My UPS was happy.
