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/TestIn order to maintain the battery state of charge while storing the vehicle for more than 30 days:
1. Make sure that the green dot is visible in the built-in hydrometer.
CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
2. Disconnect the battery ground cable to protect the battery from discharge by parasitic current drains.
When the battery cannot be disconnected:
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 or may be permanently damaged.
