BATTERY: GENERAL MAINTENANCE
Always keep the battery cables and terminals free of corrosion. Check and clean these components about once a year.
Keep the top of the battery clean, as a film of dirt can help discharge a battery that is not used for long periods. A solution of baking soda and water may be used for cleaning, but be careful to flush this off with clean water.
DO NOT let any of the solution into the filler holes. Baking soda neutralizes battery acid and will de-activate a battery cell.
Batteries in vehicles which are not operated on a regular basis can fall victim to parasitic loads (small current drains which are constantly drawing current from the battery).
Normal parasitic loads may drain a battery on a vehicle that is in storage and not used for 6-8 weeks. Vehicles that have additional accessories such as a phone or an alarm system may discharge a battery sooner.
If the vehicle is to be stored for longer periods in a secure area and the alarm system is not necessary, the negative battery cable should be disconnected to protect the battery.
Remember that constantly deep cycling a battery (completely discharging and recharging it) will shorten battery life.
