Battery Inspection

Common Causes of Failure
The following are most common causes of battery failures.
- Accessories are left on overnight or for an extended period without the generator operating.
- Driving at slow speed for short periods.
- Electrical load exceeding generator output particularly due to addition of aftermarket equipment.
- Defects in charging system.
- Battery abuse, including failure to keep battery cable terminals clean and too tight or too loose battery hold down clamp.
- Mechanical problems in electrical system such as shorted or pinched wires.
- Deterioration of battery due to long-term use.

Visual Inspection
Check for visible damage, such as cracked or broken case or cover, which may lead to loss of electrolyte. If visible damage is noted, replace battery. Determine cause of damage and make corrections as needed.
