Battery: Service and Repair
Methods of Preventing Over-Discharge
CAUTION:
-
If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt booster battery.
-
After connecting battery cables, ensure that they are tightly clamped to battery terminals for good contact.
-
Never add distilled water through the hole used to check specific gravity.
The following precautions must be taken to prevent over-discharging a battery.
-
The battery surface (particularly its top) should always be kept clean and dry.
-
The terminal connections should be clean and tight.
-
At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as "low maintenance" and "maintenance-free".
-
When the vehicle is not going to be used over a long period of time, disconnect the negative battery terminal.
-
Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a close check on charge condition to prevent over-discharge.
