Reason #: You Take An Excessive Amount Of Short Drives
The most significant use of car battery energy is when you start up the car, essentially giving the engine a jolt to set it into motion. It’s when you start to drive that the alternator begins to provide recharge. However, if you regularly take short drives that don’t have enough time to replace the energy used to start the vehicle, then you’ll likely begin to see issues with battery drainage.
This potential reason for battery drain is one of the harder ones to identify solidly, but if nothing else on this list seems to stick, this may be the issue. While you don’t have to go overboard with changing up your driving habits, it will help your battery more if you aren’t always taking very short drives.
Youre Taking Too Many Short Drives
Cranking the engine takes a tremendous amount of power from your battery, but as mentioned previously, the alternator recharges your battery while the engine runs. If youre frequently going on short drives, though, the alternator might not have enough time to properly recharge your battery between pit stops especially if you have an older battery. In the long run, frequent short trips can shorten your car batterys lifespan.
