There could be a lot of reasons for a battery to get hotter than usual. A car battery can usually endure all kinds of weather if it is used regularly and is taken care of. Little heat does not harm anyone but if you’re uncomfortable touching the battery of your car even for a few seconds. You should be worried.
Here are a few reasons why our battery might be overheating
Overexertion of battery
The primary reason for your battery going lava is that you have been driving for a long period without giving your car a well-needed rest. Prolonged use creates a lot of heat, and this heat fails to dissipate or radiate properly. This can have negative effects on your car battery as it can shorten its lifespan.
You have a weak battery
In case you have a weak battery your car’s alternator have to work hard. The alternator converts the battery direct current (DC) into alternating current (AC), hence the name. Converting to AC from DC is necessary for the electrical components (e.g., interior and exterior lights and instrument panel) of your car work. On a weak battery, the alternator has to do more work than normal to keep the battery charged. This continuous charging will heat up the battery.
Your car’s alternator is faulty
A faulty alternator may also be to blame. A defective alternator causes the battery to heat up. The fault may lie with the voltage regulator of the alternator. If the voltage regulator of an alternator is faulty, it might lead to overcharging of the battery and hence the generation of more heat which can damage both the alternator and the battery.
You are overcharging your battery
Overcharging of your car’s battery may also be to blame for its overheating.
When the battery is charged more than its capacity, the ionic repulsion intensifies and hence generates more heat than usual. Avoid overcharging to ensure a longer life for your battery.
You have a faulty charger
Sometimes the charger may cause overheating of your car’s battery. You may not be using the original charger provided to you by the company, or your charger may have been subjected to some wear and tear, or it may have failed to withstand the test of time. It is also possible that there is some malfunction in your charger circuit that is causing the heating.
Some other reason
Even after making sure that all the things mentioned above are in order and finding that there is nothing wrong with them. There might be some other stuff that is wrong with your car battery. Batteries are a complex bunch, you know! So keep your car in good condition and get timely maintenance. Have a professional mechanic check your car out and find out what may be causing overheating of your car’s battery.
