70–90% [1] Self-discharge rate. 10%/month. Cycle durability. 2,000 cycles. Nominal cell voltage. 1.2 V. The nickel–cadmium battery ( Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation Ni–Cd is derived from the chemical symbols of nickel (Ni ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A Nio battery swap station at a carpark in Beijing. Battery swapping or battery switching is an electric vehicle technology that allows battery electric vehicles to quickly exchange a discharged battery pack for a fully charged new one, as an alternative to recharging the vehicle via a charging station.

Pre-charge. Peak inrush current into a high voltage capacitor upon power up can stress the component, reducing its reliability. Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be ...
