AGM batteries offer the following advantages over conventional batteries:

Sealed maintenance free design means you don’t have to worry about checking water levels.

AGM technology will not leak or corrode on paint and chrome.

They have less internal resistance which offers more CCA amperage than wet batteries.

By nature AGM batteries are more heat and vibration resistant than conventional batteries, both which contribute to the large majority of failures in motorcycle applications.

Slower self discharge rate (longer shelf life) means battery can sit for extended periods of time without constant monitoring.

The sealed AGM battery requires very little maintenance during storage. The advanced technology eliminates the need to monitor and maintain water levels. The sealed design means much longer periods between charges when the battery is inactive.
