VRLA / AGM technology in BMW batteries

The battery utilizes AGM (Absorbent Glass Mat) technology, in which the electrolyte is absorbed into glass fiber separators. This construction improves shock resistance, reduces the risk of leaks, and allows for more stable operation across a wide temperature range. The VRLA (Valve Regulated Lead Acid) solution refers to a valve-regulated design, which promotes a controlled gassing process and reduces the need for maintenance.

The 12V voltage and 90Ah capacity parameters, combined with a high starting current, make this battery suitable for vehicles equipped with numerous energy consumers, comfort systems, and advanced control modules.

Purpose and compatibility with BMW vehicles

The offered battery belongs to the Batteries category and is an original BMW part, which facilitates matching with factory electrical installations. The design is intended for cooperation with energy management systems used in modern BMW models, including systems that monitor charge status and onboard network load.

Thanks to the presence of the OEM part number and interchangeable numbers, the battery can be precisely matched to a specific vehicle configuration, minimizing the risk of electrical parameter or mounting mismatches. This is particularly important in cars with extensive electronics, where the correct choice of battery affects the proper operation of controllers, safety systems, and comfort features.

Performance characteristics and operational parameters

AGM technology provides good resistance to deeper discharges and frequent charging cycles, which is important in vehicles operated in urban traffic with frequent engine starts and the operation of numerous consumers at low speeds. Stable output voltage promotes the proper operation of sensitive electronic systems, and the appropriately selected capacity supports trouble-free starting even under higher installation loads.

The product has a specific weight, which results from the use of a classic lead-acid construction in the AGM version. The mass of the battery translates into appropriate plate density and parameter stability over a long period of use, while maintaining proper mechanical rigidity of the casing.

Product condition and service application

The battery is offered in a used condition, making it a cost-effective solution compared to new OEM components. It can be used as a service element when replacing a worn-out power source in a BMW vehicle, when the priority is to maintain compliance with factory specifications and reduce repair costs.

Before installation, it is recommended to perform a standard verification of charging parameters in the vehicle and, if necessary, adapt the battery in the diagnostic system if the specific BMW model requires it. This allows for proper monitoring of the battery status by the vehicle's electronics and extends its effective service life.
