Primary Cell Batteries

Primary batteries, or primary cells, generate power when they are connected immediately. Primary cells are mostly or commonly used in movable devices that have low current drain, are used only periodically, or are used well away from an different power source, such as in alarm and communication circuits where other electricity is periodically obtainable. Disposable primary cells cannot be constantly recharged, since the chemical reactions are not easily reversible and the materials which are active cannot return to their original forms. The manufactures of Battery mention against trying to recharge primary cells. In general, these have higher energy densities than rechargeable batteries, but disposable batteries doesn’t perform well under high-drain applications with loads under 75 ohms (75 Ω). Common types of disposable batteries include zinc–carbon batteries and alkaline batteries.
