No, nickel-cadmium (Ni-Cd) batteries are not completely maintenance-free. They require periodic upkeep, including checking electrolyte levels, performing equalizing charges, and managing the memory effect to maintain consistent performance. Regular maintenance helps extend battery life, improve charging efficiency, and ensure reliable operation in emergency lighting and backup power systems.
