All batteries require some amount of maintenance, but if yours has vent caps, it requires a little bit more. Here’s what you need to know about both general battery maintenance and how to maintain a battery with caps.

General Maintenance:

  1. Make sure that the battery is dry and free of corrosion.

  2. Clean the terminals and posts to prevent corrosion.

  3. Have the battery tested regularly.

  4. Disconnect the battery cables if the car will be in storage for 30 days or more.

Vents:

  1. Using a flathead screwdriver, pry off the vent caps.

  2. Inspect each cell for the right amount of water.

  3. Top off each cell if low.

  4. Replace the vent caps.

Tip

Vented batteries are rare, but you may have one. Check to be sure. Consider replacing it with a maintenance-free battery if you don’t want to have to periodically check the battery cells.
