Accutronics has launched two new lithium-ion batteries in its Intellion series of credit card sized batteries. Designed to provide a high level of functionality and safety the CC2300 and CC3800 batteries allow integration of smart lithium ion battery into handheld portable products with minimal effort and cost.
The batteries feature an active electronic protection system that prevents them from being overcharged, over discharged or short circuited and to ensure that the battery will remain safe if externally abused. In addition, they have an impedance tracking fuel gauge that constantly tracks battery status, providing information such as remaining battery capacity, state of charge, run time to empty, battery voltage and temperature.
