A: First of all, begin by unclipping the battery cover to remove the vehicle's battery, afterwards disconnect the battery cables beginning with the negative cable, take out the hold-down strap or clamp, and lift out the battery. Check for corrosion on the battery tray and clean it. To reinstall follow the reverse procedure. After that, it is necessary to drive about 5 miles for the engine management system to relearn optimal settings. If you are testing a battery, perform specific gravity checks every three months for standard and low-maintenance batteries using a hydrometer or use a battery condition indicator or voltmeter for maintenance-free batteries. If your battery is completely discharged it is better to have it charged by a dealer or automotive electrician because of the higher charge rate and need for constant supervision.
