Maintenance free batteries with charge indicator (magic eye) without cell caps, checking
Identification
-
Battery equipped with permanent cell cover -2-.
-
Charge indicator -1- displays electrolyte level and charge condition.
CAUTION!
Under no circumstances should cover -2- be removed. Battery will be damaged and become unusable.
NOTE:
-
As the charge indicator is located in a single cell, the indication is only valid for that cell. An exact assessment of battery condition should always
be confirmed by performing a load test. See:
-
If the charge indicator on batteries in excess of 5 years old are colorless, DO NOT attempt to top and/or recharge battery. Battery must be
replaced.
-
Air bubbles that occur normally during battery charging (even during vehicle operation) may adversely affect charge indicator reading. To obtain
an accurate reading, gently tap the charge indicator with a screwdriver handle or rock the vehicle in order to displace any possible air bubbles that
have formed.
