Battery Charging
Battery chargingWARNING Gases given off during charging are explosive. Do not smoke or allow sparks or flame near a charging battery.
Battery charger must be turned off when connecting or disconnecting cables on battery
CAUTION: Do not allow battery voltage to exceed 17 volts. If battery begins gassing (boiling) violently when charging, reduce charging rate. Do not disconnect battery while engine is running
Note: Follow battery charger manufacturer's instructions. Before testing a battery that has been charged, load battery with 15 amps for 1 minute to remove surface charge
Battery with removable caps
If battery level is low and water is added, fast charge battery for a few minutes after battery begins gassing (boiling). Slow charging current should be approximately 10% of battery capacity. Fast charging should be approximately 80-90% of battery capacity. Remove cell caps while charging
- charge battery according to table:
Sealed batteries
Only slow charge sealed batteries. Sealed batteries, sometimes called "maintenance free," will not accept high rate of charge, making it necessary to charge it for up to twice as long as battery with removable caps. Also, voltmeter reading will not increase as rapidly as when charging battery with removable caps
WARNING: Battery acid can cause severe burns. When working with electrolyte always wear goggles, rubber gloves, and apron. If electrolyte is spilled on skin or clothing, flush at once with large quantities of water. If it gets into eyes, immediately flush with large quantities of water for several minutes and call a doctor.
Batteries produce explosive gases. Keep flames and sparks away from batteries. Do not smoke near batteries
CAUTION: Before working on any part of electrical system disconnect battery ground strap.
Never run alternator with battery disconnected
