dry cell
B2Technical/Everyday
Definition
Meaning
A type of electrical battery that uses a paste electrolyte, making it non-spillable and portable.
A primary electrochemical cell with a low-moisture paste electrolyte, commonly used in household devices like torches, remote controls, and portable electronics. It contrasts with 'wet cell' batteries which use liquid electrolyte.
Linguistics
Semantic Notes
The term is a compound noun. It specifically refers to the cell's construction (dry electrolyte) rather than its chemical type (e.g., alkaline, zinc-carbon). Often used interchangeably with 'battery' in casual speech, though technically a battery contains multiple cells.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling remains the same.
Connotations
Identical technical meaning. In both regions, it's associated with common, disposable power sources.
Frequency
Equally common in technical contexts. In everyday UK English, 'battery' is more frequent; in US English, 'AA battery' or specific type names are more common than the generic 'dry cell'.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'сухая камера' (dry chamber) or 'сухая ячейка' (dry cell in a biological sense). The correct equivalent is 'сухой элемент' or 'батарейка'.
Common Mistakes
- Using 'dry cell' to refer to rechargeable batteries (like NiMH). Confusing it with 'dry battery', which is a broader term. Misspelling as 'drycel'.

FAQ
Frequently Asked Questions
No, a typical car battery is a lead-acid wet cell (or sealed AGM battery), as it contains a liquid or moistened electrolyte, not a paste.
Generally, no. Most dry cells are 'primary' cells, meaning they are disposable and not designed to be recharged. Attempting to recharge a standard dry cell can be dangerous.
An alkaline battery is a specific, improved type of dry cell. 'Dry cell' is the general category based on electrolyte form; 'alkaline' specifies the chemistry (zinc and manganese dioxide with an alkaline electrolyte).
It is called 'dry' relative to earlier 'wet' cells which used free-flowing liquid acid. The electrolyte in a dry cell is immobilised in a paste or gel, so it does not spill.
