Tesla Pre-Refresh Model S 12V AGM OEM Battery

12V Battery Service light appearing on your Tesla's HUD? High-Tech Battery Solutions is an official authorized distributor for the OEM C&D Technologies DCS-33HIT Tesla Model S battery. The standard 12V AGM Tesla battery replacements simply do not compare the OEM C&D Tesla battery. The DCS-33HIT Series boasts an extended lifespan capable of providing true deep cycle power. Built with a computer-generated grid design optimized for high power density and long life. The C&D DCS-33HIT Deep Cycle batteries were created to help ensure long term performance to reliably deliver standby power when average conventional units fail!

This battery is designed specifically for the Pre-Refesh Tesla Model S! By carefully analyzing the Tesla batteries usage and charge characteristics, we’ve optimized the DCS-33HIT battery to perfectly suit for the rigorous demands placed the unit by the constant charge and 24x7 service of an Electric Vehicle.

Note: This battery is specifically for the Pre-Refresh Model S, check your polarity! The Refreshed Model S's will take this same style battery but in a reverse polarity.

Unlike standard ICE (internal combustion engine) vehicles, the 12V AGM battery located in the Tesla is always on, constantly working. The unit runs the auxiliary functions of your Tesla, this battery would power everything except propelling the vehicle. Tesla separates the batteries in their vehicles to power critical systems in the event the high-voltage battery is disconnected in a a crash or accident, battery cell failure or any faults in the high-voltage system. The secondary battery will maintain and power ALL of your critical systems.

The critical systems powered by this battery include: airbags, the main car computer (MCU), windows, valves and coolant pumps, seatbelt pre-tensioners, horn and various latches (doors, trunk, frunk, glovebox) all those functions powered by a single 12V secondary battery. Which is precisely why guaranteeing the best possible battery for your Model S is one of the most important steps in maximizing the power from your Tesla Model S!
