Quick Answer
STORAGE IN ATTACHED GARAGE: Generally, it's acceptable to store batteries in an attached garage as long as the space is well-ventilated, protected from extreme temperatures, and away from potential sources of ignition.
Battery Storage Requirements
When storing batteries in an attached garage, ensure the space is well-ventilated with a minimum of 3 square feet of free space per battery. This allows for air circulation and helps to dissipate heat generated by the batteries. For example, if you have 4 deep cycle batteries, provide at least 12 square feet of free space.
Ventilation and Safety Considerations
Batteries emit hydrogen gas, which is highly flammable, during charging and discharging. Adequate ventilation is crucial to prevent the accumulation of this gas. Consider installing a ventilation system with a minimum of 10 CFM (cubic feet per minute) airflow to remove gas and moisture. This may involve installing a dedicated ventilation fan, such as a solar-powered or battery-powered unit.
Best Practices for Garage Battery Storage
To ensure safe and efficient battery storage in an attached garage, follow these guidelines: Store batteries away from fuel sources, such as gasoline or propane, and ensure they are at least 3 feet away from any open flames or sparks. Maintain a clean and dry environment, and avoid storing batteries near electrical panels or other potential ignition sources. Regularly inspect battery terminals and connections to prevent corrosion and ensure optimal performance.
