The Anton Bauer 8475-0139 26V LPD Quad is a specialized, high-voltage battery maintenance station designed for the professional conditioning, discharging, and testing of four Anton Bauer 26V Gold Mount batteries simultaneously. Unlike a standard charger, this unit functions primarily as a discharger and conditioner, playing a critical role in battery fleet management for broadcast and film production facilities. Its core purpose is to maintain the health and maximize the lifespan of expensive 26V battery packs by performing controlled discharge cycles, which helps prevent "memory effect" in older NiMH chemistries and calibrates the battery's internal fuel gauge in modern lithium-ion packs for accurate runtime reporting. The "Gold Mount Plus" designation indicates compatibility with Anton Bauer's intelligent battery communication system, allowing for precise monitoring and control during the conditioning process.

The unit is engineered for reliability in 24/7 operation within professional environments. It features four independent bays, each capable of performing a controlled discharge of a battery to a specific voltage threshold at a safe, preset rate. This process is often followed by a full recharge cycle, effectively "reconditioning" the battery. By systematically cycling batteries that have been in storage or showing inconsistent performance, the LPD Quad helps ensure that all batteries in a fleet deliver their rated capacity and provide reliable runtime on set—a non-negotiable requirement for mission-critical productions. This type of equipment is essential for rental houses, large production studios, and broadcast facilities that maintain a large inventory of high-voltage batteries and need to guarantee their performance and longevity.
