History of 10440 Batteries #

The 10440 lithium-ion battery is a relatively new type of battery, having only been available since the early 2000s. It is a smaller version of the popular 18650 lithium-ion battery, which has been used in many electronic devices for decades. The 10440 is a 3.7V, 3.2Ah battery that is about the size of a AA battery.

Typical Chemistry #

The 10440 battery is a lithium-ion battery, meaning it is composed of a positive electrode made of lithium cobalt oxide, a negative electrode made of graphite, and an electrolyte made of a lithium salt dissolved in an organic solvent. The battery is also known as an ICR battery, which stands for “ion-coupled reaction”, referring to the chemical reaction that takes place between the electrodes and the electrolyte.

Typical Use #

The 10440 battery is a popular choice for many small electronics, such as flashlights, laser pointers, and digital cameras. It is also used in some hearing aids and medical devices. Due to its small size, it is also a popular choice for DIY projects and prototyping.

Design #

The design of the 10440 battery is similar to that of the 18650 battery, but with a smaller form factor. It is cylindrical in shape, with a diameter of 10.4 mm and a length of 44.0 mm. It has a nominal voltage of 3.7V and a capacity of 3.2Ah. It has a maximum continuous discharge current of 2.5A, and a maximum peak discharge current of 6A. The battery also has an internal protection circuit to prevent overcharging and overdischarging.

The 10440 battery is also known for its low self-discharge rate, meaning it can hold its charge for a long period of time. This makes it an ideal choice for applications that require long-term storage.
