GMCELL 1.5V Recahrgeable Lithium USB AA Battery                                      

The GMCEE 1.5V USB rechargeable lithium  ion battery advantages:

Stable constant - voltage output:It is equipped with a 1.5V voltage - stabilizing circuit, which can maintain a constant voltage output of 1.5V throughout the discharge process. Compared with nickel - metal hydride batteries with a standard voltage of 1.2V and a gradually decreasing voltage during discharge, this battery can provide more stable power for devices with strict voltage requirements, ensuring the stable performance of devices. For example, devices such as thermometers, blood pressure monitors, and Oculus Quest controllers can avoid measurement inaccuracies or abnormal device operation caused by voltage insufficiency or fluctuations when using this battery.

High energy density: As a lithium - ion battery, it has a high energy density and can store more electrical energy than nickel - metal hydride batteries and alkaline batteries of the same volume and weight. For example, some high - capacity 1.5V USB rechargeable lithium - ion batteries can have a capacity of over 2500mWh. The high energy density reduces the frequency of battery replacement during device use, meeting the long - term use requirements of various devices.

Convenient charging: It adopts a USB interface for charging and can be conveniently charged through various USB devices such as computers, power banks, and USB chargers. There is no need to use a special charger, and it can be charged anytime and anywhere when going out, which greatly improves the convenience of charging.

Long cycle life: It can be repeatedly charged and used for more than 2000 times. Compared with nickel - cadmium batteries and nickel - metal hydride batteries, which can only be charged and discharged about 100 times, it can save users a lot of costs and time for purchasing batteries during the entire use cycle, with high economic efficiency.

High safety: The battery is equipped with a protection board inside, which has multiple protection functions such as over - charging protection, over - discharging protection, short - circuit protection, and over - current protection. It can effectively prevent safety accidents caused by various abnormal situations of the battery, making it safer and more reliable to use.
