Battery Care

Caring for Your Battery

Regardless of the season, your car battery may require attention.

While Interstate’s automotive, commercial, and marine/RV batteries are considered maintenance-free products under normal operating conditions, extreme changes in temperature may require your battery be checked more frequently to make sure you're not left stranded.

Use our Dealer Locator to find one of 250+ Interstate Dealer locations throughout the tri-state area where you can have your battery tested.
Maintaining Batteries
How do I maintain my battery?
Follow these guidelines every three to six months to extend the life of your low-maintenance Interstate battery:
Maintain Water Level. If your battery has removable vent caps, you should regularly check the water level and add water when it is low.
Keep Terminals Clean. Visually inspect the terminals and cables at least once a year, especially in hot temperatures, for signs of corrosion. If dirty or corroded, clean the connections with a scraper and wire brush. This will ensure a good connection and proper starting.
Keep Case Clean. Keep the top of the battery clean of heavy dirt and oil with a cloth dampened by ammonia or a 50/50 solution of baking soda and water. Then rinse with clear water and allow to thoroughly dry.
Keep Battery Charged. If your vehicle is not driven weekly, it may be necessary to charge your battery before use. Lack of use is hard on a battery, especially an automotive battery which is designed to be charged regularly by an alternator. Any unused battery, regardless of its chemistry, will self-discharge over time and, if allowed to remain discharged, will undergo severe positive grid corrosion and battery failure. The rate of discharge depends on the type of battery and the storage temperature. So, it's important to keep your battery charged.
If you prefer that your mechanic take care of your battery, be sure to ask him (1) to maintain the water level and (2) to keep the connections and case clean of corrosion and dirt.

As batteries age, do their maintenance requirements change? Yes. Typically the specific gravity gets higher and gassing increases due to some battery deterioration and/or loss of reserve capacity. An older battery normally requires more charging.
