Car batteries have been used in cars since the dawn of the industry. Since then not much has changed in how they are made or how they are used.

  At the beginning of the Nineteen Twenties, car manufactures began to introduce electric starters, which made car batteries more common.

Owners of classic car  need to pay extra attention to the car battery to  ensure it has enough power to start the engine and will last a long time.  A good battery should last between three and four years, but only about one in three will last that long.

The majority of restored classic cars are kept in storage more than they are driven, so the batteries tend to wear out faster, In fact, one of the most common problems with old cars is problems with the battery or the electrics.

With the right care, it is possible to get more use out of a battery.  It just takes a bit of common sense and some information.

Maintaining a classic car battery will help prolong its life and ensure that it performs well when you need it to. Here are a few tips that will help to make sure thos will  not happen.

Corrosion can build up on the terminals of a battery, which can interfere with its ability to charge and discharge properly. Clean the terminals and cable connections with a wire brush and baking soda solution to remove any build-up.

To neutralise the corrosion and get a head start on removing it, either use a battery cleaning spray or use a paste made of baking soda and water. It is possible that a wire brush will need to be used to remove the corrosion from the terminals if there is a significant amount of it.

After scrubbing, residue left behind should be removed by rinsing with water. The battery should then be dried.

Most classic car batteries are of the flooded lead-acid type, which means that they have removable caps that allow the owner to check and maintain the level of the electrolyte. The electrolyte should be kept at the proper level, which is usually about 1/4 inch above the top of the lead plates.

A classic car battery will last longer if it's kept in a fully charged state. It is best to charge the battery before it gets too low to avoid overcharging, which can shorten the battery's life.

Avoid discharging the battery all the way down. Most lead-acid batteries have a limited number of deep discharge cycles and will have a shorter life if frequently deeply discharged.

High temperatures can reduce the life of a classic car battery. Keep the battery in a cool, dry place when the car is not in use, and avoid storing the car in direct sunlight or in a hot garage.

Like all batteries, classic car batteries have a limited lifespan and will need to be replaced eventually.

To check for battery age the first thing you need to do is check for a sticker that has the date printed on it in a format that is easily recognisable. For instance, "3/3015" would indicate nothing more than the fact that the battery was produced in March of 2020.

If the battery does not have a date sticker, it should an alphabetic and numeric code typically located on the lid of the battery, but it can also be found directly on the battery itself. It can be up to multiple characters long, and the first two characters in the sequence provide information about the date.

The age of the battery should also be considered and if it exceeds the manufacturer recommendation, it's time to consider replacement.

: If the classic car is to be kept in storage for an extended period, it's a good idea to remove the battery and store it in a cool, dry place.

Doing so will  help to prevent the battery from being entirely drained by the various electrical devices.  If  the battery in the car unattended for an extended period of time, it may cause the battery to become damaged, and you may even need to replace it.

Disconnection will help prolong its life and keep it in good condition for when it is ready to use the car again.

This helps to prevent the battery from being entirely drained by the various electrical devices, such as the clock and the on-board computer system.

Therefore, if you leave the battery in the car unattended for an extended period it may cause the battery to become damaged, and you may even need to replace it.
