akkuilla

Akkuilla is the adessive plural form of the Finnish noun akku, meaning a battery or batteries, and is used to indicate location or presence of multiple batteries. The base word akku refers to a rechargeable energy storage cell. In Finnish, the adessive case signals “on” or “at” a surface or location, so akkuilla translates roughly to “on the batteries” or “at the batteries” when used in a sentence. As a plural form, it appears in contexts such as inventories, equipment listings, or signage where multiple batteries are involved.

In everyday Finnish, akkuilla is not typically used to describe that a device runs on batteries. To express power from a battery, speakers commonly use phrases like toimii akulla (works on a battery) or operations described with akkukäyttöisesti (battery-powered) rather than the bare adessive plural form akkuilla. Therefore, akkuilla is best understood as a grammatical inflection rather than a standalone concept with a broad semantic scope.

Etymology and related terms: Akku is a loanword from the English accumulator, often via Swedish or German. Related Finnish terms include paristo (battery, especially disposable) and akut (the plural nominative form). The distinction between akku (rechargeable) and paristo (non-rechargeable) is common in technical and consumer contexts.
