• Replacing 8x RBC43 Batteries in a APC SUA3000RM2U UPS

    So it finally happened. The Batteries in my APC SUA3000RM2U finally went bad. I’ve had them for over 5 years so I am happy with there life. I’ve had to replace UPS Battery Cartridges and Packs before when working as a Data Center consultant. It is usually a simple and straight forward task. I would RMA the Battery Cartridge or Pack, if it’s under warranty, and then the¬†manufacturer would send me back a new Battery Cartridge or Pack already filled with new batteries. Hot swap it with the old one and you are done.

    However, this time it was my home unit and I don’t have warranty coverage or the extended one(usually purchased by an enterprise). So I went online looking for a Battery Cartridge replacement, $300-400!!!, o my! So I decided to try and replace the batteries themselves rather than the entire Battery Cartridge. I was able to find a pack of 8 batteries for around $83 with free expedite shipping. The following steps were what I did to replace each APC RBC43 battery inside the battery cartridge.
