Power up your portable electronics with this 104058 3000mAh rechargeable Li‑Polymer battery. Perfect for wireless speakers, GPS navigators, dash cams, LED lights, and various DIY 3.7V electronic projects. Each battery delivers factory-rated 3000mAh capacity with built‑in protection against overcharge, over‑discharge, short circuit, and overcurrent — ensuring safe and reliable operation for your devices.
Manufactured with high‑quality Grade A Li-Polymer cells and equipped with integrated PCM protection board. The protection features include overcharge protection (detection 4.26±0.05V), over‑discharge protection (detection 2.75±0.1V), overcurrent protection, and short circuit protection. With a cycle life of 500+ cycles retaining 80% of original capacity, these batteries offer reliable long‑term performance. CE, RoHS, and UN38.3 certified for safe transport and use. Operating temperature range: charge 0-45°C, discharge -20 to 60°C — suitable for devices used in various environments.
Compatibility Note: Fits devices that use 104058 battery model with 2‑wire connection. No connector included — red and black wires only, ready for direct soldering. Please verify your device’s original battery dimensions (approx. 10×40×58mm), voltage (3.7V), and connection polarity before ordering (red wire = positive “+”, black wire = negative “-“). Suitable for DIY electronic products with power consumption less than 11.1Wh. Not suitable for high‑power power tools or drones.
Installation Tip: If your original battery has a connector (JST or similar), carefully cut and solder the plug from your old battery to these wires using heat shrink insulating sleeves to connect same color wires together (red to red, black to black). Always verify polarity before soldering and do not reverse the connection.
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. Always use a compatible 4.2V Li-Po charger (≤1500mA). Store in a cool, dry place when not in use.
