The Genuine BMW Advanced Charging Battery Tender is a BMW-engineered battery maintenance charger designed to keep your BMW's battery in optimal condition during storage, extended periods of inactivity, or simply during the night between daily drives. Modern BMW vehicles, particularly those with sophisticated iDrive systems, multiple ECUs, keyless entry, and active chassis electronics, have significant parasitic loads that slowly drain the battery during periods of inactivity. This battery tender is specifically calibrated for BMW battery types and management systems to maintain state of charge without overcharging, unlike generic automotive chargers that may not be compatible with BMW's battery health monitoring and registration systems.
This charger connects to the OEM service plug under the hood (on most BMW models) or directly to the battery terminals, and automatically cycles between charging and maintenance modes to keep the battery at the correct state of charge indefinitely. The charger's output is calibrated for BMW's AGM and lithium batteries, avoiding the overcharging that damages sensitive battery chemistries. For BMW owners who store their car seasonally, use a track car occasionally, or simply want to maintain battery health between drives, this Genuine BMW charger is the correct tool for the job.
