How to Store a Car Battery

If your automobile battery will be sitting unused for more than a month, you should consider removing it and storing it. This will help your battery last longer by reducing wear and allowing it to keep a charge better.

There’s a lot more to keeping your batteries now than just putting it on a garage shelf. For battery storage, follow these procedures.

1. Double-check That the Battery Is Completely Charged

Keep your battery fully charged at all times. This will assist to avoid the majority of damage and degradation that might occur during storage.

2. Look for Any Potential Harm

With age, batteries can fracture or corrode, so examine your battery for any signs of damage. If the damage is severe, it may need to be replaced.

2. Look for Any Potential Harm

Before the battery is put away, it should be cleansed of corrosion and electrolyte buildups. This type of grime can clog the terminals, causing the battery to drain more quickly.

Cleaning a battery at home is as simple as washing it with a wire brush and a combination of baking soda and water. Wipe off the battery’s housing according to the manufacturer’s recommendations once the deposits have been removed.

4. Locate a Suitable Storage Facility

While you may expect your battery to discharge in some capacity while it’s in storage, you can take steps to restrict how much power is lost. Temperature is the most important element that affects the discharge rate of your battery, aside from the amount of time it has been kept.

A battery should be kept in a dry, well-ventilated location with a temperature between 40 and 60 degrees Fahrenheit. Avoid areas that may get excessively hot or cold, since this may cause the battery to deplete more quickly. Also, stay away from regions where the humidity is high, since this might cause the battery to deteriorate.

5. Charge the Battery on a Regular Basis

It’s critical to keep an eye on your battery when it’s in storage if you want to get the most out of it. Make it a habit to inspect your batteries at least once every 12 weeks (though the more frequent, the better). If feasible, use a voltmeter to check the voltage to see how much power your battery still has. Recharge it when it’s just 70% charged or less.

Final Words

You now know how long a car battery lasts without being used and how to maintain it safe using the information above. You will not be driving your car at times throughout the winter season. In that scenario, make sure the car battery is properly kept and ready to use once the winter season is through. Ascertain that it is kept in a warm and pleasant setting.

The longer your battery is left uncharged, the worse the issue becomes. Run the car on a regular basis if possible. The battery’s durability will be improved as a result of this. Always remember to clean the automobile batteries before storing them. Check the date your battery was made, don’t short the connections, and never keep it near open flames or heaters for safety reasons.
