Helpful Information Before attempting to replace an automotive battery, make sure the area around the battery is safe to work. Batteries are filled with acid and they can emit both powdered and liquid acid on and around the battery. By sprinkling baking soda over the battery and then rinsing with water will reduce the chance of getting chemical burns. Gloves are highly recommended along with protective eyewear and clothing. Knowing the workings of a battery or battery cables can be helpful. Best Practices
- When testing an automotive battery, make sure area is neutralized of all battery acid.
- Never touch a conductive object between the terminals of any battery.
- Match or exceed cold cranking amps when replacing a battery.
- Recycle old battery at any an approved recycling center.
