Alkaline cell

The common 1.5 V single-use cell, with a zinc negative electrode and manganese dioxide positive in potassium hydroxide electrolyte. It is the reference point for most people’s idea of a battery, and is not rechargeable.

Medical device batteries

Batteries for devices from infusion pumps and portable monitors to pacemakers. External equipment uses rechargeable packs tested to IEC 62133 and approved as part of the device under IEC 60601-1, built under ISO 13485 with full traceability; implants use hermetic primary cells such as lithium–iodine and lithium–silver vanadium oxide, chosen for years of predictable life.

Primary cell

A cell designed to be discharged once and not recharged, such as an alkaline or lithium–manganese dioxide cell. Its reaction is not reversible in practice, unlike the secondary cells this glossary is mostly about.

Silver oxide cell

A primary button cell with a silver oxide positive and zinc negative in alkaline electrolyte, giving 1.55 V on an exceptionally flat curve until nearly empty. That stability suits quartz watches and precision instruments; the cells carry SR codes such as SR626SW.

Zinc–air cell

A cell whose positive electrode uses oxygen from the air, so almost all its volume is zinc and its energy density is very high. It powers hearing aids as a primary cell; rechargeable versions are being developed for grid storage.
