Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 .
In order to maintain the battery state of charge while storing the vehicle for more than 30 days:
- Make sure that the green dot is visible in the built-in hydrometer.
- Disconnect the battery ground cable to protect the battery from discharge by parasitic current drains.
When the battery cannot be disconnected:
- Maintain a high state of charge.
- 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.
