3.8v Rechargeable Mini Button LiPo Battery

Lowest Price and Available Samples

Lipol Battery has been producing lipo battery for more than 8 years, The diameter 3.8V mini button lipo battery range from 4 mm to 6 mm. The 3.8V mini button lipo battery should be used for AirPods, smart cards, smart labels, micro-speakers.

Higher Energy Density 3.8V liPo battery

The high power consumption of mobile devices means that high energy density is more important than any other feature. This means that shortening the service life is an acceptable compromise; since the average consumer changes their smartphone every two years, service life is not a significant requirement.

In essence, higher voltages are just another way to increase overall energy density.

why pursue higher voltages 3.8V lipo battery rather than just higher capacities?

Therefore, we have conducted some research and found that there are new developments in 3.8V lipo battery technology that can be used at higher voltages for 3.8V lipo batteries for mobile devices and hobbyist / RC applications. Correctly, silicon graphene additives are used in the anode to prevent corrosion at higher voltages, so that they can be charged to 4.35V or even 4.4V. This results in a slightly higher energy density, but charging the lipo battery to a higher voltage shortens its life.

3.8V lipo battery for smartphones and tablets

Compared to 3.6V or 3.7V per lipo battery typical of most lipo batteries in other types of consumer devices. A 3.8V lipo battery is used. The charging voltage of this 3.8V lipo battery is 4.35V, and the power-off energy is 3.00V.

Safety 3.8V Micro LiPo Battery (Button Cells)

For ordinary lipo battery, it is not safe to periodically charge to 4.35V, which is basically a safety margin. For a new 3.8V lipo battery, 4.35V is a safe voltage, even if charging to this voltage will accelerate lipo battery degradation.

3.8V liPo battery with long working time

We have tested and know that 1500mAh 3.8V lipo battery will work longer than 3.7V 1500mAh lipo battery. The more stable the discharge voltage, the better the capacity of the 3.8V micro lipo battery.

More important than anything else is the risk of battery ventilation/fire. Improved chemical properties mitigate this risk and allow higher voltages.
