IV. Battery Diagnosis - Driver Related Condition
In no cause is found for a discharged battery and the battery tests good, a light may have been left on, or the driving habits of the owner may be such that, especially with many short trips and repeated starts, the generator does not get a chance to recharge the battery between starts. If this situation is suspected, the driver should be instructed in ways to reduce battery drain. Limiting the use of the rear window defogger, using the low blower setting whenever possible, are helpful in this regard.
