How to Assemble an APC RBC7 Smart UPS Battery(4)

Tips
1.Make sure you set the batteries on a level surface when you join the two together and line up the sides at the same time. You have about four minutes to adjust the alignment. If Plastic Weld® sets misaligned, you will not be able to correct it.

2.Removal of fuse and cable from dead pack: Remove fuse first, cable second.

3.Installation of fuse and cable to newly assembled pack: Cable first, fuse second.

4.For testing and calibration, throw your circuit breaker, or plug the UPS into a power strip that does not disconnect ground and turn the power strip switch off. Doing this ensures the UPS maintains ground, which is important for calibration.

5.For really long run times, use car/marine batteries from your local auto parts place (deep cycle are the best). You are looking for max RA (Reserve minutes).I have an APC 700 that has been running for several years from two $48 car batteries. I made special cables to go from the car batteries to the spade terminals, and put each connector in vinyl tubing to prevent welding.
