Where is the BMW Series 1 battery?
The electrical system of a car is fundamentally connected via the car battery. In essence, it functions as a battery, storing electricity that powers the car’s electric systems. Consequently, it is crucial to keep the battery in top functioning order. Unbelievably, a battery has a shelf life and will eventually lose its effectiveness. In other words, the battery’s internal chemical reactions will stop producing electricity. A battery can hold an usable charge for around 3 to 5 years until it loses its ability to do so. This is the justification for thinking about installing fresh batteries. There is a chance that the dirt on the connection points will cause the battery to lose electricity. Corrosion, which can eventually accumulate between battery terminals and cable connections and result in poor connection contacts, is a problem. This suggests that the battery will no longer benefit from an alternator recharge. It will eventually exhaust its energy and be unable to continue producing electricity. Cleaning the cable and battery connections may enable you to use the battery once more by bringing it back to full efficiency. If the car was abandoned for a while, the battery can also run out of power. Recharging the battery could be able to fix it in this situation. You’ll need a battery charger before you can start the recharge.
Important! It’s possible that some BMW 1 Series (E87, E81, E82, and E88) automobiles have an IBS (Intelligent Battery Sensor) technology. That indicates that your Service center has to register the newly replacement battery. Avoiding battery registration could result in a failure of the power management system and inaccurate readings on the on-board computer’s display.

1. Remove the positive terminal cover:
Positive connection disconnected:
Disconnect the battery’s venting pipe if it’s there (1). Some vehicles use battery ventilation systems to exhaust hydrogen-containing generated gases outside.
Remove the old battery from the battery compartment (notice that the battery is heavy and improper lifting could cause back injuries):
Before installing the new battery in the car’s battery compartment, do not remove the plastic terminal caps.
To guarantee optimal contact, if necessary, clean battery wires of any corrosion or debris before joining.
Instead of unplugging the battery, connect the cables, beginning with the positive terminal.
How can I tell if the battery in my key fob needs to be changed?

This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.

How long does it take to charge a BMW key battery?
The EWS ring antenna from KL R charges the battery inside the key head inductively using a coil antenna included into the key. Integrated electronic circuitry in the key regulates the charging process.
- The lifespan of a vehicle is the same as the service life of a radio-control key when operated normally.
- The battery will eventually run out if the FZV keys are not utilized (i.e., kept in a drawer) after about 1.5 years.
- Approximately 30 hours are needed to fully charge a drained battery.
- After a 30-minute charging period, the remote control can be used roughly 15 times (driving time).
A transponder chip houses the important information. The transponder chip is a wireless EEPROM that may be read and written. It is powered by the steering lock’s ring coil. When the key is in the ignition switch, power is delivered electromagnetically from KL R.
Data is transferred and the battery is charged using the power supply. The transponder chip has undergone new development, enabling this.
Every time a FZV key is pressed, as in prior systems, the battery charge level is also displayed. Three consecutive low power condition messages are received by the FZV electronics before the GM sets a fault signaling a low battery in a particular key. The bus system also notifies the LCM, and an instrument cluster matrix message is sent to the driver to warn him or her.
When five consecutive messages showing a charged battery status are received, the fault will be immediately removed if the battery is recharged (used to drive the automobile).
