APPENDIX A ESTIMATING BATTERY CHARGE TIME - VENT CAP BATTERIES
For batteries with removable vent caps fill the top of each battery cell with distilled water to the level recom-
mended by the battery manufacturer, but do not overfill. To calculate the approximate charging time required to
fully charge a battery, it is necessary to determine the specific gravity (or percent of battery charge) using a
hydrometer. Use this technique if battery vent caps can be removed. Check each cell. If there is one cell with a
very low specific gravity compared to the other cells, there is probably a shorted cell in the battery. Replace the
battery.
The following chart converts hydrometer readings into percent of charge values.
