Lithium-polymer battery
3.7 V, 1.3 - 3.28 Ah | UPF series
SANYO Energy
It's a high energy density, 3.7/3.6V battery that is not compatible with ordinary batteries, but is widely used in the portable equipment market. It uses lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode), and the lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge.
Features
High voltage of 3.7/3.6V lets you cut down on the number of batteries you use.
High energy density minimizes battery size and weight, making it perfect for use in small portable equipment.
No metallic lithium is used so charging and discharging are very safe.
No memory accumulation so it provides a full charge every time.
The outer casing in square type batteries is an aluminum alloy, so overall battery weight is lower.
