2-3.5 Installing Backup Batteries
Perform the following steps to install the backup batteries
1. Using Appendix A, Battery Capacity Calculations, calculate the size of the battery required
for the application.
2. Ensure that the batteries are being placed into service within three (3) months of the ship
date if stored at about 75°F (24°C) or within one (1) month if stored at 100°F (38°C). For
longer storage time, they require charging per manufacturer’s specification to prevent
permanent loss of capacity.
3. Observing polarity, connect the two (2) or four (4) 12-volt series-wired batteries of the
required ampere hour (AH) capacity to TB12 (Batt Out) using battery cable
(P/N 06-129925-002). Refer to Figure 2-11.
