The following checks are to be completed with the battery on open circuit and prior to application of a charging voltage or load. Any required corrective action is usually obvious or detailed in the previously mention publications.

BATTERY OPEN CIRCUIT CHECKS

| COMMENTS/STATUS
---|---
1. Individual batteries are installed with a minimum of 0.5” spacing to allow free air circulation.|
2. Visual appearance of batteries is OK and there is no evidence of container or terminal damage.|
3. Individual batteries are clean and clear of debris.|
4. Open circuit voltage of the individual battery strings and individual batteries within the strings is measured and recorded.|
5. The individual string and unit voltages are a minimum of 2.03 V/C x number of cells connected in series (eg. 6 cells = 12.18 VDC minimum and 180 cells = 365.4 VDC).|
6. Polarity of all the individual batteries in the system is visually verified as correct.|
7. Each individual string of batteries within a system of parallel strings is individually cabled to the load or a common tie point.|
8. Each individual string of batteries within a system of parallel strings has a separate disconnect, circuit breaker or fuse in its output.|
