Ladattava nappiparisto Varta V2/250H-SLF++/- 250 mAh 2,4 V

Rechargeable button cell Varta V2/250H-SLF++/- delivers a nominal voltage of 2.4 V and a usable capacity of 250 mAh in a compact, low-profile metal housing. The cell is intended for devices that require a small rechargeable power source with stable voltage output over multiple charge cycles. Its design emphasizes compact dimensions and compatibility with applications where space is limited and repeated charging is required.

Advantages

The Varta button cell provides consistent voltage under light to moderate loads and supports many charging cycles compared with single-use cells. Its compact diameter and low height allow installation in slim housings and precision instruments. The rechargeable chemistry reduces waste and operational cost for devices with regular maintenance schedules, while the metal case offers mechanical robustness for handling and device integration.

Suitable for

• Precision instruments and measurement sensors
• Medical monitoring devices and handheld diagnostics
• Small portable electronics with low current draw
• Backup power for memory and real-time clocks in compact devices

Key specifications

• Nominal voltage: 2.4 V
• Typical capacity: 250 mAh
• Button cell format with low profile metal housing
• Rechargeable cell chemistry suitable for multiple charge/discharge cycles
• Intended for low to moderate continuous or intermittent current draws

How to use

Install the cell according to the device manufacturer’s polarity markings and contact layout. Use a charger compatible with the specific rechargeable chemistry and nominal voltage of the cell; follow the charger manufacturer’s instructions for charge current and termination behavior. Avoid charging at excessively high currents or temperatures. Inspect contacts for corrosion or dirt before installation and ensure a secure mechanical fit to prevent intermittent contact.

Recommendations

Store and charge the battery within the temperature range recommended by the device or charger manufacturer. For reliable long-term operation, cycle the battery periodically and avoid deep discharges below the device’s recommended cutoff. Replace the cell if capacity drops significantly or if the cell shows physical damage or leakage.
