18650 Cylindrical NCA Ternary Lithium Battery for Tesla Model X (2015-2019)OE#1088790-00-B

1. Product Overview

This 18650 cylindrical NCA ternary lithium-ion battery cell is a direct OEM replacement, specifically engineered for Tesla Model X (2015-2019) with exclusive OE part number 1088790-00-B. Adopting premium nickel-cobalt-aluminum (NCA) cathode material consistent with Tesla’s original 18650 battery specifications—used in Model X 90kWh packs with dual-motor all-wheel-drive systems—it delivers stable energy density (262Wh/kg), reliable electrical performance and superior single-cell consistency. It perfectly matches the original battery module structure, vehicle BMS (Battery Management System), and Tesla’s proprietary liquid cooling thermal management system, widely applied for Tesla Model X battery pack repair, module refurbishment, capacity recovery and aftermarket replacement, complying with strict automotive-grade reliability standards and meeting B2B OEM/aftermarket demands. 

2. Key Features

- Exact OE replacement with part number 1088790-00-B, fully compatible with Tesla Model X (2015-2019) original battery packs that use 18650 cylindrical cells, the tried-and-tested cell format for Tesla’s flagship Model X.

- Standard 18650 cylindrical form factor (18mm diameter × 65mm height), equipped with premium NCA ternary lithium cathode material as original OEM specification—NCA chemistry is Tesla’s premium choice for high energy output and performance, ideal for Model X’s luxury positioning.

- Stable high energy density (262Wh/kg), supporting stable high-current discharge to meet the power demands of Tesla Model X’s dual-motor all-wheel-drive system and 90kWh battery pack configuration, ensuring excellent range and acceleration performance.

- Low internal resistance (≤33mΩ), ultra-low self-discharge rate and long cycle life (≥1100 cycles), ensuring long-term performance stability and reducing replacement frequency for B2B clients, aligning with Tesla’s battery durability standards.

- Seamless adaptation to Tesla’s exclusive liquid cooling system and original BMS, guaranteeing safe operation under various harsh automotive working conditions—critical for managing the large number of 18650 cells in Model X’s battery pack architecture.

- Excellent single-cell consistency, ideal for series-parallel combination in large-scale EV battery pack assembly, matching Tesla Model X’s modular battery architecture with hundreds of 18650 cells per module.

- No memory effect, supporting random shallow charging and discharging, effectively extending the overall service life of the battery pack and enhancing cost-effectiveness for aftermarket users, consistent with Tesla’s battery maintenance recommendations.

- Strict automotive-grade quality control throughout the production process, meeting the high standards of Tesla’s original battery components and B2B OEM/aftermarket demands.
