Li-Pol battery 300mAh 3.7V Excellent quality

Li-Pol battery 300mAh 3.7V Excellent quality
Cables are connected to the battery and a heat shrink protective sleeve is installed.
The cables are terminated with a pin connector from the integrated circuit base – see photo.
The offered battery is a production remnant.
Each battery has been tested, is functional, and the parameters given are as described.
Battery life is closely dependent on the charge and discharge voltages and currents.
To maintain long service life, do not exceed the currents and voltages given in the specifications.
Two batteries connected in series work perfectly in place of a 9V battery 6F22.

Attention!
The battery is not flat, it has a cylindrical structure, a roller type.
The sale is for the battery only, without the additional pins visible in the photo.
The battery does not have any electronic protection!
Be especially careful, a short circuit or reverse connection may cause a fire!
The battery is shipped partially charged to a storage voltage of 3.7V
The price offered is for one piece plus shipping costs.
