• Battery cell caps -2- covered with plastic foil.
• Charge indicator -1- displays electrolyte level and charge condition.

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 battery test. Refer to Battery, testing  .
• 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.
