How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2] Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells.
Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.

The maximum continuous current drain of Ni–Cd battery is commonly around 15C. Compared to NiMH battery where usable maximum continuous current drain is not more than 5C. Nickel–metal hydride batteries are the newest, and most similar, competitor to Ni–Cd batteries. Compared to Ni–Cd batteries, NiMH batteries have a higher capacity and ...
The fine-grain structure also provided better anti-corrosion properties and enhanced battery performance in a 4 mol/L NaOH solution. At a current density of 10 mA/cm², the fine-grain anode showed a 41.5% increase in capacity density and a 55.5% increase in energy density compared to the coarse-grain anode.
