Direct Replacement Siren Alarm Battery

This 300mAh 6.0V 1.80Wh battery replaces the original siren alarm power source in compatible BMW models including F44, G30, G32 and G29 series vehicles. It matches part numbers 2 447 710-01 and 84 10 2 447 710 with a fully decoded chip that works like the factory unit.

Sustained Alarm Reliability

The 300mAh capacity delivers consistent voltage for alarm signalling over extended periods rather than only brief bursts. A new cell reaches its best performance after two or three complete charge and discharge cycles, supporting dependable operation when the siren is triggered.

Upgrade From Depleted Original Cell

This unit replaces an exhausted or failing factory siren battery that no longer holds sufficient charge for reliable alarm activation. The jump is worth it when the original cell shows reduced runtime or fails self-test, restoring full security system function without vehicle-specific programming.

Questions about this item

Does the 6.0 V 300 mAh siren alarm battery generate noticeable heat or noise during continuous operation?

The battery is a sealed 6.0 V 300 mAh unit with no moving parts, so it runs silently and produces no measurable heat under normal alarm-system loads.

What existing connector or wiring must the vehicle already have for this 55.00 x 37.10 x 14.70 mm battery to plug in directly?

It replaces the original siren alarm battery using the factory connector for part numbers 2 447 710-01 and 84 10 2 447 710, so the vehicle must retain that OEM plug.

Will this 6.0 V 300 mAh replacement work alongside the original electronics in a G30 540i xDrive without firmware updates?

Yes, the fully decoded chip is designed to match the original battery’s communication protocol, so it functions with the existing alarm module in listed models such as the G30 540i xDrive without any software changes.
