What Are Battery Tenders?

Investing in a battery tender will help keep your battery charged and is especially necessary for anyone who leaves their vehicle inactive for two weeks (e.g. vacation) or longer (e.g. snowbirds). A tender will ensure the battery maintains its charge at proper storage voltage when not in use.

The two types explained below can be purchased at any of our centres, or from your CAA Mobile Battery Service professional.
