PROPER BATTERY MAINTENANCE
- Check the condition of the battery. Make sure that the solution is at an ample level.
- Check for contact. Make sure that the terminals are always clean. A corroded clamp will
have little contact on the post thus stopping current flow. Apply mineral grease or
petroleum jelly on the terminals to prevent corrosion. - Check for loose clamps, terminals, and body ground.
- Before starting the vehicle, check for unwanted load. Make sure that all accessories are
switched “OFF”. - For diesel engine vehicle, maintain a good set heater plugs. A quick heating engine will be
quick to start. - In the condition that the battery discharged, it must to prevent sulfating.
- Check the charging system. The ideal volt reading is 13.4 volts to 14.4 volts for 12 volts
system and 26.8 volts to 29.2 volts for 24 volts systems. - Spouting of the electrolyte solution indicates overcharging. Check the voltage regulator.
- Boiling when the RPM increases indicates overcharging. Check the voltage regulator.
- Frequent addition of the distilled water indicates leak or overcharging.
- Broken and exploding cases were caused by overcharging or plugged vents.
- Intermitting presence of power indicates loose contacts. Check terminal and body ground.
- Sparking during installation indicates shorts or reverses polarity. Stop installation and
check connections. - Presence of smoke inside the cell indicates shorted cell.
- High specific gravity reading indicates high sulfur content in solution. Reduce the level of
solution and add distilled water according to concentration of solution.
