For reliable starts, follow a routine preventive maintenance program for your vehicle's battery. When servicing the battery, use appropriate safety equipment and precautions. There is the possibility of the production of flammable hydrogen gas around the battery, avoid sparks, smoking or matches near there. Ensure that charging of the battery takes place in a well-ventilated area. Inspect if there is any damage in connection with corrosion, loose connections and insulating materials on batteries. It is always advisable to clean up your car's battery with a solution of warm water mixed with baking soda. They should be coated using a zinc-based primer before painting.

To disconnect the battery, loosen the cable end bolt and disconnect the cable from the negative battery terminal. It is important to isolate the cable end to prevent accidental contact with the battery terminal.

To reinstall the battery, follow the reverse procedure.

Clean cable clamps and terminals with a solution of warm water and baking soda while wearing safety gear.

Before servicing the battery, always ensure the engine and accessories are turned off and disconnect the negative battery cable.

The battery load test evaluates the ability of the battery to operate the starter and other accessories during periods of heavy amperage draw.

Avoid creating sparks, smoking, or lighting matches near the battery since it produces hydrogen gas, which is flammable and explosive.

Use a battery lifting strap that attaches to the battery posts to lift the battery safely and easily.

Remove the battery hold down clamp and carefully lift out the heavy battery.

Use a slow-rate charging method with a one or two-amp charger to minimize strain on the battery, especially if the vehicle is driven infrequently. For a faster charge, use a charger with a higher amperage but no more than 1/10th the amp/hour rating of the battery. Rapid boost charges should be reserved for emergencies as they can damage the battery. A trickle charger typically charges a battery in 12 to 16 hours.

Ensure all accessories are turned off, then connect one lead of a digital ammeter to the disconnected negative battery cable clamp and the other lead to the negative battery post. A drain of approximately 100 milliamps or less is considered normal.
