TESTED Tesla Model S 85 Battery Module 24V 250Ah 5.2 kWh Lithium 1009312-00-D

### **TESTED Tesla Model S 85 kWh Battery Module 1009312-00-D (Gen 1) - Great for Off-Grid or hobby applications** ### **Description:** #### **✅ Key Details** - **Part Number:** Tesla **1009312-00-D** (Interchangeable with -00-E) - **Voltage:** ~24 V Nominal - **Capacity:** ~ 5.2 kWh – 5.3 kWh (New Rated) - **Application:** Ideal for **Off-Grid Solar Storage or DIY EV Projects** #### **🚗 Vehicle History & Condition** This module was professionally pulled from a **2012 Tesla Model S 85 kWh** High Voltage (HV) battery pack. - **Vehicle Mileage at Removal:** **155,000 miles** - **Reason for Removal:** The entire pack was retired due to cell **imbalance issues** (known as high cell variance) and reduced range. - **NO Accident Damage:** The module casing and internal structure are intact and free of crash damage. No moisture issues.   Capacitors appear to be fine on BMB board including C26 and C27. - **Condition:** **USED.** The module will show normal wear and tear from its time in the vehicle. - **TESTED:** **Guaranteed to power on and have voltage.** Final capacity is reduced due to mileage and balancing issues, which is common for used modules. **We strongly recommend rebalancing the cells before installation in an EV or off-grid system.** #### **⚠️ Important Note for Buyers** - This is a used module with **high mileage (155k)** and **known imbalance issues** from its EV service life. It is _not_ a plug-and-play solution for every EV without diagnostic work and rebalancing. - **Voltage and capacity testing is required** by the buyer for their specific application. - Due to the nature of used lithium-ion batteries and high-voltage parts, this item is being sold **AS IS** with no guarantees or warranty beyond being a genuine Tesla part and powering on at the time of shipment. Includes the 2 power bolts and 2 orange bolt covers. See attached photos for proof that the BMS board is functional and that all cell voltage sense wires are operational. You can see each of the 6 brick voltages on the photo along with the 2 temperature sensor readings. There is a 77mV difference between highest and lowest brick in this module. Module TSN# T12KD036137 Tests were performed with a Tesla Battery Module Monitor (TBMM) is a diagnostic tool that connects to individual Tesla battery modules to quickly assess their health by checking voltage, temperature, and communication status. It is powered via USB-C and connects to the battery module's BMS port, providing instant feedback with a green "good" or red "bad" indicator and a web interface to view detailed information. This tool is useful for diagnosing issues without fully disassembling the battery pack, identifying imbalances between cell groups, and assessing used modules before purchase. Module will be shipped in a custom plywood crate.
