Service & Install — Early in the Model S program we identified durability and fitment gaps in the OEM 12 VDC battery (C&D 33 Ah AGM). Our engineering team designed a direct-fit replacement that delivers longer service life and stronger performance while matching Tesla’s 180° reversed post orientation—which eliminates generic local auto-parts store options.
We sell and ship this battery nationwide, maintaining a large inventory in a climate-controlled warehouse, and offer local installation that preserves vehicle settings. Each replacement includes a memory-safe swap, BMS wake/sleep validation, and a final 12 V health report. Core return and certified recycling supported.
Designed specifically for the Tesla Model S, this 12-volt battery is engineered for the unique duty cycle of an EV which include frequent micro-cycles, constant float/charge maintenance, and 24×7 vehicle systems support. Our design team analyzed Tesla charge behavior and accessory loads to build a pack optimized for long life under continuous standby service.
