Place battery under heavy load (as during engine cranking or with a variable resistor tester)
and test cell voltage while under load.
Certain conditions must be met before testing.
• Battery must be 60 to 100°F (16 to 38°C).
• Electrolyte level must be correct in all cells.
• Battery must be at least half charged.
• No obvious defects.
1. Check voltage per manufacturer’s specifications.
2. If readings are low, recharge and retest.
3. If readings remain low, battery should be replaced.
