Question 3

How would you save a sulfated battery?

Accepted Answer

A sulfated battery can sometimes be saved. Connect a headlight bulb between the positive and negative posts and allow the bulb to totally drain the battery. Then recharge it slowly. Repeating the cycle of charging and discharging the battery will sometimes knock enough of the sulfation off the plates so that the battery can charge. If after two cycles the battery still will not accept a charge, replace it.

When a battery will not accept a charge, it is MOST-Likely:

Accepted Answer

A)  dry 
B)  fully charged 
C)  sulfated 
D)  corroded 
A)  dry 
B)  fully charged 
C)  sulfated 
D)  corroded
