The car battery is an essential part of the vehicle. In this article, we will tell you how to keep it perfect condition.

A car battery undergoes severe temperature fluctuations during its lifespan. The enormous heat produced by the engine rapidly deteriorates the battery capacity. In cold weather conditions, a battery can last up to five to six years whereas during hot weather conditions the lifespan of the battery gets reduced to almost three years.

Your car’s battery gets continuously charged by the alternator when the car is on and running. When the car is parked idle for several days, it rapidly loses the charge of the battery and sometimes goes beyond the minimum level of charge required to start the vehicle. When this scenario persists for occasional times, the lifespan of the battery deteriorates leaving your car vulnerable to sudden breakdown.

7 Tips to Keep Car Battery Life Healthy

You can follow the below-mentioned tips to keep your car's battery healthy and working for many years:

1. Switch On The Car Battery At Regular Periodic Intervals

The battery under the hood loses its charge when it is not used for an extended period of time. The power of the battery drains rapidly. To avoid this, it is recommended to start your car and taking it for a ride once a week. When a car battery loses its charge completely, it will then require a jumpstart to start the car.

2. Minimise Battery Usage When The Engine Is Turned Off

Car batteries tend to discharge more quickly when the engine is not running. The interior lights and music systems drain significant battery power which hampers the total lifespan of the battery. Whenever exiting the car, make sure the interior lights and accessories are switched off.

3. Keeping The Battery Clean

Do not let dirt assemble on the battery, which can result in draining of the battery charge through the dust of the battery casing. This can also result in a short circuit that could make the battery dead. The terminals of the battery also corrode over time, so it is required to clean the terminals with the help of a brush to reduce dirt related corrosion.

4. Minimise Heat Exposure

When exposed to extreme heat, the battery life drastically lowers down and makes the fluids in the battery evaporate. This happens even with new sealed batteries. During winters the battery does not need much charge to start the car, but batteries can sometimes fail even during winters because of the damage already done during the summer season. To protect your car from excess heat during the summer season always park it in a shady place or a garage whenever possible. Always look for a tree under which you can park your car during the daytime.

5. Check The Battery Voltage Every Month

A lead-acid’s battery life will reduce considerably when it is left uncharged or is left at half charge. Keep an eye on your battery life by checking its voltage once every month with a voltmeter. A healthy car battery should have a minimum charge of 12.7 volts or above. Whenever the voltage lowers down to 12.5 volts, it is recommended to recharge the battery. A car battery with 12 volts or less is considered completely dead.

6. Add Distilled Water Whenever Necessary

Maintain a healthy equilibrium by mixing distilled water to the battery and extend the battery life. During summer, hot weather conditions can result in evaporation of the battery fluid. Adding distilled water will help in reducing the damage of cells caused due to overheating.

7. Keep the battery insulated

Protect your car battery with insulated covers. As newer variants of cars are being manufactured for better fuel efficiency and aerodynamics, it has resulted in the shrinkage of hood space. This affects the airflow in the engine, making the battery more susceptible to heat and resulting in a shorter life span. Protect your car battery from both extreme heat and cold with an insulation wrap.

Protect your car from breakdowns by simply maintaining your car battery with the above points. Not only you can save money from frequently buying a new car battery, but you can also make a difference in the preservation of the environment.


In a nutshell, the above-mentioned steps are sure to help you keep up the battery health of your car. However, it is in the nature of cars to be affected by wear and tear or meet with mishaps of other kinds. These types of events are unforeseen and there is very little we can do to prevent it.
