FAQs about the Varta V250H NiMH Battery

Is this battery a direct replacement for a cell?

No, the V250H is a rechargeable battery with a 1.2 V nominal voltage. It should only be used in devices that are explicitly designed for the use of NiMH batteries and feature an appropriate charging circuit. Usage in devices for 1.5 V or 3.0 V primary cells is not possible.

How often can the V250H battery be recharged?

The cycle stability of an NiMH battery strongly depends on the usage conditions such as charge current, depth of discharge, and temperature. Under optimum conditions, however, the Varta V250H can achieve several hundred charge and discharge cycles.

What does memory backup application mean?

Memory backup means memory retention. The battery supplies a memory chip (e.g. RAM) or a real-time clock (RTC) with power when the main device is switched off. This ensures that important data, configurations or the time are retained.

How should this battery be disposed of?

As a rechargeable battery, the V250H must not be disposed of in household waste. Please return it to special collection points for batteries and accumulators in retail stores or at local recycling centres to ensure proper recycling.
