Battery with Visual Indicator, Enhanced

This is a maintenance-free battery with liquid electrolyte (wet battery).


Do not remove any of the labels on the battery and do not add distilled water. Only perform a visual inspection.


Do not check or charge batteries that have a visual indicator that is bright yellow. Jump starting must not be used!

There is a risk of explosion during testing, charging or jump starting.

These batteries must be replaced.

The battery is installed in certain Stop/Start vehicles due to special requirements. "EFB" is written on the battery cover to identify this battery. "EFB" stands for enhanced flooded battery ( enhanced wet battery).

An "EFB" battery may only be replaced with another "EFB" battery.

An "EFB" battery has a visual indicator for checking the battery electrolyte level.
