akumulatorowy

Akumulatorowy is a Polish adjective that denotes something powered by an accumulator, i.e., a rechargeable battery, or relating to such a device. The term is used to describe equipment and systems that depend on an energy storage unit rather than a direct power connection. In everyday language, akumulatorowy is often found in technical, consumer electronics, and automotive contexts. It can be translated as "battery-powered" or "rechargeable-energy storage-based."

The word derives from akumulator (accumulator, battery), itself borrowed from German Akkumulator and introduced into Polish through technical language. The adjective is formed with the suffix -owy, producing gendered forms such as akumulatorowy (masculine), akumulatorowa (feminine), and akumulatorowe (neuter).

Usage and nuance: Compared with bateryjny, which also refers to devices that use batteries, akumulatorowy emphasizes the use of rechargeable energy storage. In many cases the terms are interchangeable, but akumulatorowy tends to appear in contexts explicitly involving a rechargeable battery rather than disposable ones.

Examples: wiertarka akumulatorowa (cordless drill) and kosiarka akumulatorowa (cordless lawn mower) are common phrases. In industry, one may speak of a system akumulatorowy describing a power storage subsystem, or of a pojazd akumulatorowy to denote a battery-powered vehicle, often phrased as pojazd z napędem akumulatorowym.
