Rechargeable NiMH battery Varta V2/80H-SLF++ 80 mAh 2.4 V

Varta V2/80H-SLF++ is a rechargeable NiMH battery with a nominal capacity of 80 mAh and a nominal voltage of 2.4 V, designed for small, low-power electronics and backup functions. The cell follows a compact standardized format suitable for devices that require a stable low-voltage source and the ability to recharge rather than replace disposable cells. Its chemistry and capacity make it appropriate where intermittent current draw and periodic charging are expected.

Advantages

The NiMH chemistry delivers consistent voltage during discharge and allows many recharge cycles, reducing waste compared with single-use batteries. With an 80 mAh capacity and 2.4 V nominal voltage, this battery is compact and suited to tight spaces while providing predictable performance in low-power applications. Rechargeable capability supports cost-efficient replacement and maintenance cycles in equipment designed for periodic battery service.

Suitable for

• Small electronic devices with low current draw
• Memory backup modules and RTC (real-time clock) systems
• Portable sensors and measurement instruments
• Remote controls and small wireless peripherals
• Devices intended for repeated charging and long-term use

Key specifications

• Chemistry: Nickel–metal hydride (NiMH)
• Nominal capacity: 80 mAh
• Nominal voltage: 2.4 V
• Cell format: compact standardized rechargeable cell
• Intended use: low-power and backup applications

How to use

Install the battery according to the device manufacturer’s polarity markings and contact requirements. Charge the cell with a charger compatible with NiMH chemistry and with appropriate charge current for small-capacity cells; follow the charger and device instructions to avoid overcharging. For backup applications, ensure the battery is charged before installation and periodically check charge level to confirm reliable operation. Replace the cell when capacity noticeably decreases or if it no longer holds charge.

Usage recommendations

Store the battery in a cool, dry place and avoid prolonged exposure to high temperatures. Use a charger that supports NiMH cells and select a charge current suitable for small 80 mAh capacities—slow or smart chargers are preferable. Observe device-specific guidance for installation and replacement intervals to maintain reliable low-voltage supply and preserve battery life.
