Intelligent battery sensors are something that most new BMWs have. These keep an eye on the amperage and voltage of your BMW’s battery. After changing the batteries, you have to set up the IBS system. If not, your BMW will charge them too much.
BMW batteries should be programmed for models made after 1990 because they have an intelligent battery sensor (IBS). During programming, the sensor is reset so that the car can check the health and state of the battery and charge it accordingly.

What Happens if You Don’t Reprogram BMW Battery?
If you forget to programme the battery in your BMW, it could cause problems. Most of the time, though, you can still drive it. When you programme the battery, the smart battery sensors are reset. These find out how much electricity is moving through your car.
