Do batteries come with a warranty?
Yes! All batteries include manufacturer warranties. Warranty length varies by battery type - standard batteries typically 1-3 years, premium AGM batteries 3-5 years.

Heat is the #1 enemy of battery life. Hawaii's warm climate accelerates chemical reactions inside batteries, reducing lifespan by 1-2 years compared to cooler climates. Premium AGM batteries handle heat better.
