If you are looking for a battery solution for your electronic devices such as bluetooth speaker, smart watch, GPS tracker, e-book reader, bluetooth headsets etc., then let Cowon provides you some li-ion polymer batteries to choose will be the best way for the developing of your products.

Li-polymer battery is one of the most preferable battery which customer will choose in many equipment, as it is with small size, light weight and without size limitation. It also has high energy density, long cycle life and no memory effect characteristics.

Thousands of models and various shapes are freely for your option. Using the most minimal self-discharging cells and with the best PCB solution to make the battery more efficient.

Lithium-ion batteries are very popular these years. Machines like scanners, mobile phones, POS machines and laptops etc. all can be found with these batteries. They become the most common rechargeable batteries in our life because of the best energy densities, no memory effect and low self-discharge characteristics.

The lithium-ion battery that provided by Cowon can be cylindrical or prismatic with aluminum case or li-ion button cell batteries.

Li-ion cylindrical batteries like 3.7V ICR series, especially the most ICR18650 battery that you may know, it’s the most widespread models. We are not only provide you with the grade A of cells made in China, but also the imported brands made in Japan and Korea.

Lithium thionyl chloride batteries are high-performance energy-based batteries with a variety of notable features and applications. Its 3.6V voltage rating and highest specific capacity make it suitable for a variety of uses, including real-time clocks, device and instrument power supplies, and CMOS memory backup. With a nominal operating temperature range of -40°C to +75°C, the battery’s excellent low and high temperature characteristics, low self-discharge rate and 10-year shelf life make it a reliable and long-lasting power source.

However, it should be noted that there are some specific precautions when using this battery. It is prohibited to cause short circuit, charge, over-discharge, burn, squeeze, use beyond the specified temperature range, assemble or disassemble the battery.

Its 3V nominal voltage is twice that of traditional dry batteries, making it suitable for applications requiring higher voltage levels. Stable and reliable discharge voltage, excellent storage characteristics, low self-discharge rate of less than 2% and long shelf life make it a reliable power source for various devices.

In addition, the cell’s excellent fast pulse discharge characteristics and wide operating temperature range of -20°C to +60°C further enhance its versatility and suitability for a variety of applications. These properties make the battery ideal for use in devices that require stable and reliable power, even in challenging environmental conditions.

The 3V lithium cylindrical batteries are commonly used in water, gas, and electricity meters, as well as in portable electronic devices such as walkmans, CD players, cameras, camcorders, and LED flashlights. The CR lithium button cell batteries are widely used in various everyday devices including calculators, remote controllers, clocks, electronic watches, electronic dictionaries, laptop BIOS, and payment terminal backups.

Cowon can process the battery pack in series or in parallel based on customers’ requests, with the matched cables, connectors or solder tabs.

Cowon has years of experience in designing various kinds of rechargeable Ni-MH battery packs. The battery packs can be customized according to the design of customers’ final products.

The Ni-MH cells that we use for battery assembling are carefully selected. All the cells are grade A made in China or Japan, with low self-discharging rate and high efficiency rate.

The available cell shapes including Ni-MH button cell (20H, 60H, 80H etc.), Ni-MH cylindrical battery (AA, AAA, 2/3A, 4/5A, SC, 1/2D etc.), Ni-MH prismatic battery (F6, 4/5F6, 7/5F6 etc.). The energy type and power type (high drain) cells are also available.

Specified parts like cable, thermistor and connector can be processed based on requests. Customized label service can be provided as well.
