Making your vehicle’s battery last as long as possible doesn’t usually take too much effort along the way. The most important bit, however, is keeping your vehicle’s charging and electrical system in proper operating condition. Keeping the battery charged up, and not deeply discharging it too frequently often helps it last longer. Aside from the major parts, inspect it semi-regularly and clean off any corrosion you find on the terminals, and coat them to prevent it from happening again. The corrosion inhibits charging, and discharging, of the battery and can put a strain on your whole charging system.
