Obtaining your own voltage readings with a cheap digital multi-meter is an easy DIY test. After the automobile has been idle for a while, check the battery voltage. Make sure that every light—interior and exterior—is off. While the car is operating, you should also check the voltage at the battery.
You can look up appropriate voltages on Google, but a fully charged battery should be represented by 12.6–12.7 volts DC. With the car running, you should see roughly 14.0 +/- volts. A significant drop below that can be a sign of an alternator problem.

Pay attention to These Signs
It’s crucial to keep an eye out for these warning indications that your BMW’s battery is starting to fail because it’s so simple to unintentionally drain your car’s battery.
- Slow engine cranking is one of the first indications that a battery is starting to fail in a BMW, even if the engine starts. Don’t wait until the car’s engine entirely shuts off before stopping. Bring your car into your go-to repair shop right away to get the battery checked to prevent further damage and possible accidents.
- An examination of the battery is required if an engine won’t start. It’s likely that you need a new battery if your car won’t start at all and you have to ask your neighbor to jump start it.
- Even though it would seem normal for cars to have trouble starting in the cold, this is actually a sign of a weak battery. Don’t ignore this one. The last thing you want is to be trying to start your car while trying to get home from work in the parking lot!
- The lights won’t turn on: If the headlights on your BMW aren’t turning on, you most likely don’t have a lightbulb problem. Most likely, the battery is failing. Take your BMW to the local technician to have the battery checked out.
- requiring a boost: Even if you unintentionally left your lights on and require a jump start this morning, doing so could harm the battery in your car. This can imply that the battery in your BMW lives less than it was intended to. Keep a close eye on your BMW’s battery to make sure it’s in excellent shape and still receiving power from your alternator if you’ve ever had to jump start it.
How can I tell if my BMW needs a new battery?
- lowering the headlights.
- a greater demand for jump starts or engine revving.
- When you turn the key or press the button, the engine starts more slowly.
- abnormal power variations

The battery used by the BMW is lead-acid. You can pick between two types: gel or absorbent glass mats (AGM). The OEM AGM battery is what the maker advises you to use in place of the stock battery.
The majority of BMW vehicles employ either performance or advanced batteries. Advanced batteries are used in cars with lots of electronics, whilst performance batteries are used in aftermarket modified cars.
How can I assess the health of my automobile battery?
Verify the battery’s voltage. The positive battery terminal, denoted by a red cover or a + symbol, should receive the red lead. The black lead should be connected to the negative terminal. Examine the measurement. You might need to charge your battery if the reading is less than 12.4 volts.
What occurs when the battery in a BMW is low?
Being able to recognize the warning signs or symptoms of impending failure in a vehicle might allow you to properly prepare or seek repairs before the problem can catch you off guard. The warning indicators you should watch out for in the event of a dead battery include:

Additionally, the car contains a mechanism for recharging itself, however this function is dependent upon the engine being operating. When the car is parked, just a battery with a finite capacity is being used as an energy source.
