Removal of Surface Charge

If the battery has just been recharged, or the car has been driven, eliminate any surface charge by one of the following methods:

• Allow the battery to sit for 2-3 hours.
• Turn the headlights on high beam for 5 minutes and wait 5 minutes after turning off.
• With battery load tester, apply a load of 1/2 the battery's CCA for 15 seconds, then wait 5 minutes.
