✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

The built‑in PCM protection board prevents overcharge, over‑discharge, short circuit, and overcurrent — ensuring safe and reliable operation for your devices.
The 105050 battery dimensions (10mm thickness × 50mm width × 50mm length) make it compatible with many standard battery compartments, offering a versatile replacement for the common 105048 model. Each battery delivers a stable 3.7V output with 3000mAh high capacity, extending the runtime of your devices significantly. The operating temperature range spans -20°C to 60°C for discharge and 0°C to 45°C for charging, making it suitable for indoor and outdoor applications.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3‑5 full charge cycles to reach optimal capacity. Store in a cool, dry place when not in use. Always verify polarity before soldering — red wire positive (+), black wire negative (‑).
