The Construction of the ETX30L Battery From the Inside Out.

Absorbed Glass Mat Technology (AGM)

The key to the high performance capabilities of the ETX30L stem from the AGM battery technology utilized in its production. Extremely high porous microfiber separators are placed between the lead plates concealed within the batty that completely absorb and trap the electrolyte. This enables for maximum surface coverage of the lead plates within the battery which ensures that maximum power output is achieved 24/7. Another benefit to the AGM manufacturing process is the ability to seal the battery enabling for a completely spill-proof and maintenance free design.
