Repeat steps 2 through 4 until you have replaced all of the batteries in the RBC43 cartridge

I recommend removing and replacing one battery at a time for anyone new to the APC RBC43 Cartridge. Removing and replacing one at a time will ensure that your wiring will be correct avoiding any potential confusion that could arise.

Step 3 is important! Always re-use the plastic terminal protectors, if the adhesive is no longer usable then apply a small piece of double sided tape.
