What are Instant Amps?
Instant amps are a measure of the power discharged from a battery in .2 seconds, to your RV. This measurement allows you to truly see the power these batteries deliver to your starter motor, and why the RV starts up so well with a Lifeline AGM Battery. There is true power inside a Lifeline® Starting Battery or a Lifeline® Deep Cycle Battery.
