Product Description

Introducing the DC 3.7V Model Square Table of Rechargeable Polymer Lithium Batteries suitable for usage with 3.7V-5V electronic products. When using these batteries, please ensure careful attention to the polarity of the connector. Note that the red wire signifies the positive "+" and the black wire the negative "−". Additionally, it is advised not to reverse-charge or reverse-connect the battery.

The convenience of 3-wire batteries lies in the inclusion of red and black wires, making for a simple replacement to 2-wire batteries. In some cases, primary batteries may lack a plug or feature mismatched plugs or polarities. However, this is not an issue, as you can either directly cut and solder the plug or use our heat-shrinkable insulating sleeve to connect wires of the same color.

Choose from a variety of battery capacities, ranging from 220mAh to a high-powered 10500mAh battery, suitable for a wide range of electronic products such as mobile energy storage, power supplies, LED lights, wireless Bluetooth game headsets, outdoor video and audio equipment, electronic scales, GPS watches, cameras, e-books, and more.

Please note, however, that these batteries are not suitable for power tools or model aircraft. We also provide a 1-year warranty – if there are any quality issues within this timeframe, we will replace your battery free of charge.
