A car's battery is the most crucial piece of equipment to starting and driving your vehicle. It sends power from the starter motor to the sparks plugs, igniting your car's fuel, while also giving other systems power. This includes lights, radio, air conditioning, and more. You may be able to tell when your car battery starts to die if you find it difficult to start, have flickering lights, or a weakening alarm system

Parasitic Drain:

Parasitic drain is experienced when various components of your car keep drawing power from a 12V system even after completely removing the key. Well, given that your battery delivers enough energy to keep things like the power locks, radio presets, security alarm, and clock operational all the time, some parasitic drain is therefore normal. Nevertheless, in case of a faulty electrical system like poor installation, faulty wiring and defective fuses, larger systems could be running even after turning your car off, and this may drain your car battery.

Extreme temperature:

If you leave your car in extremely hot temperatures of over 100 degrees Fahrenheit or too cold under 10 degrees Fahrenheit, it may cause the build-up of lead sulfate crystals which can affect the lifespan of your battery. Also, if you use your car on short distances under these conditions, the battery may take a longer time to charge.

Corroded or loose battery cables:

If the connections on your battery have corroded, the charging system is affected and can't top off the battery when driving. Again, if the battery cables are loose, they ability to transfer electrical current is affected too and this makes it difficult to start the engine. Battery cables should, therefore, be checked regularly; clean them using a cloth in case they are dirty or fix them if loose.

Old battery:

Car batteries are not manufactured to stay forever. As a matter of fact, most of them have a lifespan of five years. Old car batteries cannot deliver the power the engine needs to start. After using your car battery regularly for a long time, it encounters buckling of lead-acid plates, loss of water, and plate corrosion, all of which affect its ability to hold the charge. If you want to be on the safe side, replace your car battery after 3-4 years.

Human Error:

You've most likely done this in any event once in your life you return home from work, tired and not by any means considering, and left the headlights on, didn't totally close the storage compartment, or even overlooked some inner lights. Medium-term the battery channels, and in the first part of the day your vehicle won't begin. Numerous new vehicles alert you in the event that you've left your lights on, however might not have alarms for different segments.
