The best quality cells were used to produce Newell batteries. The capacity given in milliamps is real and ensures long working time. A built-in intelligent safety system based on the IC electronics regulates the charging process. This guarantees safety and protection for the device and the user. The Newell replacement was built in lithium-ion technology. It allows for multiple charging and discharging as well as recharging at any time without the risk of the so-called “memory effect”.
