återladdningsbar

Återladdningsbar is a Swedish adjective that translates to "rechargeable" in English. It describes devices or batteries that can be replenished with electrical energy, typically from a power source, allowing for repeated use without being discarded. This contrasts with disposable or single-use items.

The concept of rechargeability is central to many modern technologies. Batteries in portable electronics such as smartphones, laptops, and electric vehicles are designed to be rechargeable. This feature significantly reduces waste and environmental impact compared to non-rechargeable alternatives. Rechargeable batteries are commonly based on various chemical compositions, including lithium-ion, nickel-metal hydride, and nickel-cadmium, each offering different characteristics regarding energy density, lifespan, and charging speed.

The term "återladdningsbar" implies a cycle of discharge and recharge. When a device is used, its stored energy is consumed, causing the battery to discharge. When connected to a charger, electrical current flows into the battery, reversing the chemical reactions and restoring its energy capacity. The lifespan of a rechargeable battery is often measured in charge cycles, indicating how many times it can be fully discharged and recharged before its performance significantly degrades. Products explicitly labeled as "återladdningsbar" are designed for this recurring functionality.
