~1min read

Maintenance-Free Battery with Specific Electrolyte without a Visual Indicator

Lead-acid battery, where the electrolyte is fixed in an absorbent glass mat (AGM). The battery is closed and equipped with breather valves.

AGM is the English abbreviation for Absorbent Glass Mat.

These batteries do not have a visual indicator because the electrolyte level is predetermined. AGM is on the battery to identify it. Note

Always replace an AGM battery with another AGM battery.
