Ultra-thin and compact rechargeable battery EnerCera battery Products
Lineup
「EnerCera Pouch」「EnerCera Coin」
EnerCera batteries are available in two types, EnerCera Pouch and EnerCera Coin. EnerCera Pouch is an ultra-thin product with thickness of 0.45 mm and good bending resistance, and EnerCera Coin is a coin-shaped product with thickness of 1.3 to 2 mm suitable for mounting on circuit boards.
EnerCera Pouch products are available in three types—a high power type, a high heat resistance type, and a fast-charging type—to accommodate a wide range of device designs. ET Series products (part of EnerCera Pouch, EnerCera Coin) have exhibited high environmental resistance. Some models allow use even at temperatures as low as −40°C, while other models offer excellent float charging resistance, making them ideal for use in backup power supply systems. These products are ideal for applications involving cold chain temperature monitoring and as power sources for IoT devices installed outdoors.
