TSB: While a vehicle is in inventory, the battery is subject to conditions that can reduce its performance and life. Batteries can become discharged due to an extended storage period, temperature, parasitic drain, or while demonstrating vehicle features and benefits in the sales process. Battery inspection and maintenance are required in order to ensure proper operation and optimal battery life. As described in this bulletin, operating the engine for 30 minutes after 60 days in storage and every 30 days thereafter will help to maintain battery State of Charge (SOC). This process supplements other movements of the vehicle as it is staged, and has specific restrictions on how maintenance is to be done. Also described in this bulletin are 2 other approved methods for maintaining battery State of Charge.
