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". Specification: - model: EN-EL18 - technology: Li-ion - capacity: 2600 mAh - current: 10,8 V Compatibility - Nikon D4, D4s,D5
