A nickel–zinc battery (Ni–Zn battery or NiZn battery) is a type of rechargeable battery similar to nickel–cadmium batteries, but with a higher voltage of 1.6 V.

Larger nickel–zinc battery systems have been known for over 100 years. Since 2000, development of a stabilized zinc electrode system has made this technology viable and competitive with other commercially available rechargeable battery systems. Unlike some other technologies, trickle charging is not recommended.
