- Disconnect the +positive terminal second but use caution to prevent metal tools from contacting any metal component of the vehicle,
- DO NOT place metal tools on or near the battery,
- Use a battery lifting strap to prevent injuries when removing the battery,
- If the battery appears cracked or swollen remove and replace with a new battery,
- If cables are corroded beyond the connectors it is advised to replace with new cables,
- Clean the corroded battery and cable ends with an old toothbrush or a brass brush using a slurry comprised of a tablespoon of household baking soda mixed with a small glass of water,
