How do you keep a car battery charged when not in use? Leaving it on will only drain the battery faster. To avoid the battery from draining faster, you need to park outside with the alarm turned on, and drive the vehicle for at least 30 minutes a week to keep the battery charged.

Preparing to Charge the Battery

Put on safety gear. Safety is necessary any time you are working on your vehicle. Begin by putting on protective eyeglasses to protect you from any falling material under the hood of the car, sparks or battery fluid in the event the battery becomes compromised.

For you to charge your car properly, you must first identify the type of battery you have. You can check it on the battery, or you may need to check the manufacturer’s website if the label is too worn to read or missing.

Wet cell batteries may be serviceable. With this battery, there are things you can do to help improve the charge and the life of your battery.

VRLA Batteries (Valve Regulated Lead-Acid Battery) are completely sealed and need no maintenance. These batteries come as Gel Cell or Absorbed Glass Mat batteries. And they’re less common in cars unless purchased as an after-market modification.

Get a Car Battery Charger

Get a charger that is appropriate for your battery and purposes. Though, some chargers work for all types of batteries except Gel Cell batteries. Also, there are fast chargers that can charge your battery faster, as well as “trickle” chargers that offer a slow but longer-lasting charge.

However, lots of newer chargers come with a microprocessor to monitor how much the battery has charged. These digital chargers will then stop the process automatically when the battery is charged completely.

Further, older, simpler chargers must be stopped manually to stop dangerous overcharging and should not be left alone for extended periods of time while connected.

Go through the charger’s manual to make sure you are using your particular unit correctly.

Disconnect And Remove The Battery From your Vehicle If Necessary

Clean the Battery Terminals

Any dirt or grime on the battery terminals can stop the charging cables from establishing a strong connection to the battery, so it’s necessary to clean the terminals thoroughly. Use baking soda and a wet cloth or a sandpaper pad to wipe out any grime or rust. Also, ensure the terminals are bare metal before proceeding to the next step in order to ensure a strong charge.

However, sometimes you may find the battery has a solid charge, but dirty terminals were preventing the electricity from flowing.

Note; Do not touch the terminals with your bare hands or skin, especially if there is any white powder on them. This powder is mostly dried sulfuric acid, and it can burn your skin if you come in contact with
