🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the full productivity of your BlackBerry Key2 with this TLP035B1 3500mAh replacement battery. Released in June 2018, the BlackBerry Key2 features a 4.5-inch IPS LCD display, Snapdragon 660 processor, and its iconic physical QWERTY keyboard — designed for business professionals and frequent typists who demand reliable performance. This Li-Polymer battery delivers the factory-rated 3500mAh capacity, keeping you powered through email management, secure communication, and all-day tasks.
Built with high-quality Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, FCC, and RoHS certified for safe transport and use — complies with all requirements for safety applicable within the territory of the EU member states. For reference, third-party retailers sell this battery for approximately $23 to $30.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches TLP035B1. This battery is compatible with BlackBerry Key2 models BBF100-1, BBF100-2, BBF100-4, BBF100-6, BBF100-8, BBF100-9, and BlackBerry KEY2 LE. Professional installation is recommended as the phone has a sealed back cover with strong adhesive. The phone is not water resistant, so water seal maintenance is not a concern after replacement.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best performance, use the original 18W Qualcomm Quick Charge 3.0 charger that came with your phone. If you don’t use the battery for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.
