Weaker Starts on Cold Mornings Could Indicate a Weaker Battery

When Your BMW Won’t Hold a Charge, it Could be Something other than the BatteryAt first, you might not think anything of it. Cars don’t exactly start as readily or easily on colder mornings, as compared to nice, warm summer mornings. However, if you notice that your car is having more trouble turning over in the morning, especially when it’s colder outside, it could be something more than just the cold air affecting the engine, creating more resistance for the flywheel to be turned and the pistons to be lifted up and down inside the chamber of the cylinders.

It could be the battery.

As a battery gets older, it begins losing its ability to provide the power the engine needs. The battery is responsible for providing power to the starter motor. That starter motor is responsible for getting that flywheel moving and all of the other components start to follow in place. When the flywheel starts moving, it’s drawing fuel into the chambers and the pistons are compressing the fuel and the spark plugs ignite it. Once it catches, the battery is no longer necessary.

It will sit idle, being charged by the alternator, and every other electrical component, including the headlights, interior lights, radio, GPS, and everything else you have plugged into it will be powered by the alternator.

If the battery gets worn out as it gets older, it will lose amperage necessary to turn your engine over. It’s a lot of technical stuff, but ultimately what you want is the moment you begin noticing or suspecting your battery may be growing weaker is to bring it to an authorized BMW service center for a test.

An experienced technician can plug into your car’s battery and test it. It could be the alternator is no longer charging the battery properly or your battery is no longer holding the charge or creating ample amperage your engine needs to get started. The colder it is outside, the greater the impact it will have on your battery, especially if it’s a weaker battery.
