Battery Protection During Vehicle Storage

Certain devices on the vehicle maintain a small continuous current drain (parasitic load) on the battery. A battery that is not used for an extended period of time will discharge. Eventually permanent damage will result. Discharged batteries will also freeze in cold weather. Refer to Battery Inspection/Test. Battery Inspection/Test

In order to maintain a battery state of charge while storing the vehicle for more than 30 days, complete the following actions:

IMPORTANT: If a green dot is not visible in the hydrometer, test the battery. Refer to Battery Inspection/Test. Battery Inspection/Test

1. Ensure the that the green dot is visible in the built-in hydrometer.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

2. Disconnect the battery (negative) ground to protect the battery from discharge by parasitic current drains.

When the battery cannot be disconnected, complete the following actions:
1. Maintain a high state of charge.
2. Establish a regular schedule for recharging the battery every 20-45 days.

A battery that has remained in a discharged state for a long period of time is difficult to recharge and may be permanently damaged.
