Pila de botón recargable Varta V500HRT NiMH 1,2 V 510 mAh

The Varta V500HRT rechargeable button cell battery is a NiMH cell that provides 1.2 V nominal voltage and 510 mAh capacity in a compact button format. It is designed for small electronic devices that require a stable low-voltage source and multiple recharge cycles. The chemistry and capacity support applications where frequent replacement of disposable cells would be impractical, offering consistent output for timekeeping, memory retention and low-drain sensors.

Advantages

This rechargeable NiMH button cell delivers a stable 1.2 V output and a 510 mAh capacity in a small form factor, allowing for long service life across many charge/discharge cycles. Its rechargeable design reduces the need for single‑use batteries and lowers operating cost and environmental waste over time. The cell maintains voltage under light to moderate loads typical for watches, medical devices, and backup memory, and is compatible with equipment that accepts standardized rechargeable button cells.

Suitable for

• Wristwatches and timekeeping devices that accept rechargeable button cells
• Medical instruments requiring a compact rechargeable power source (e.g., hearing aids, small monitors) when compatible
• Backup memory and real-time clock retention in electronic equipment
• Low-drain sensors, wireless transmitters, and small IoT devices

Key specifications

• Chemistry: Nickel‑Metal Hydride (NiMH)
• Nominal voltage: 1.2 V
• Rated capacity: 510 mAh
• Form factor: button cell (compact, low-profile)
• Rechargeable: yes — intended for multiple charge/discharge cycles
• Typical use: low- to moderate-drain applications requiring stable low voltage

How to use

Install the battery into the device according to the device manufacturer’s instructions, observing correct polarity. Use a compatible charger designed for NiMH button cells or follow the device’s built-in charging method if provided. Charge at the recommended current and monitor charging time to avoid overcharging. Before first use, ensure the battery is charged; periodic full charge/discharge cycles may help maintain capacity. Replace the cell if it shows signs of swelling, leakage, significant capacity loss, or if the device indicates battery failure.

Recommendations

Store the battery in a cool, dry place and avoid prolonged exposure to high temperature. For best longevity, avoid deep discharges and use a charger with proper NiMH charging profiles. Dispose of or recycle the battery according to local regulations for rechargeable batteries.
