Power up your portable devices with this 2‑pack 105048 / 105050 3000mAh rechargeable Li‑Polymer battery set. Perfect for lights (LED lamps, desk lamps), gradienters (digital level tools, angle measuring instruments), humidifiers (portable mini humidifiers), power banks, Bluetooth speakers, and various DIY 3.7V projects. These batteries are manufactured with genuine Grade A Li‑Polymer cells and feature a built‑in PCM protection board that prevents overcharge, over‑discharge, short circuit, and overcurrent — ensuring safe and reliable operation.
The 105048 and 105050 models are fully interchangeable — both have the same 10mm thickness, 50mm length, and similar 48-50mm width, making them a drop‑in replacement for each other in most applications. Each battery delivers a stable 3.7V output with 3000mAh high capacity, providing extended runtime for your devices. With a cycle life of 500 cycles retaining 80% of original capacity and a service life of over 1000 cycles, these batteries offer exceptional long‑term durability. Operating temperature range: charge 0‑45°C, discharge ‑20 to 60°C — suitable for indoor and outdoor use.
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 (‑).

🔋 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.
