Green Cell GR18 9V Rechargeable Battery, Nickel-Metal Hydride (NiMH), 2-Pack

The Green Cell GR18 9V rechargeable battery set provides a reliable and sustainable power solution for a wide range of household and professional electronic devices. Utilizing advanced Nickel-Metal Hydride (NiMH) technology, these batteries offer a high capacity of 250mAh, ensuring consistent energy output and extended runtimes compared to standard disposable alternatives. This 2-pack is designed for users seeking to reduce long-term costs and environmental impact by opting for a reusable power source that maintains performance over hundreds of charge cycles.

Advantages

These rechargeable batteries are engineered for high durability and operational safety, featuring modern materials that allow for up to three years of intensive use. A significant benefit is their low self-discharge rate, as they retain 85% of their stored energy even after 12 months of storage. Furthermore, they are built to function efficiently in extreme temperature conditions ranging from -20 to 60 degrees Celsius. Because they are supplied pre-charged, they are ready for immediate use right out of the packaging, preventing early capacity degradation.

Suitable for

• Wireless microphones and audio equipment
• Smoke detectors and security sensors
• Remote-controlled toys and hobby electronics
• Multimeters and professional measuring instruments
• Medical devices and household appliances requiring 9V power

When it may not be suitable

These batteries may not be suitable for devices that require a specific voltage higher than the nominal output of NiMH technology or for equipment that demands extremely high instantaneous current spikes beyond the discharge capabilities of standard 9V rechargeable cells. They are also not intended for use in chargers that are not specifically designed for Nickel-Metal Hydride chemistry.

Key specifications

• Battery type: Rechargeable Nickel-Metal Hydride (NiMH)
• Battery size: 9V (HF9)
• Capacity: 250mAh
• Quantity: 2 batteries per pack
• Operating temperature range: -20 to 60 degrees Celsius

How to use

To use the Green Cell GR18 batteries, simply insert them into your device according to the polarity markings in the battery compartment. Since the batteries arrive pre-charged, they can be used immediately. When the device indicates low power, remove the batteries and charge them using a compatible 9V NiMH battery charger. Ensure the charger is properly connected to a power source and that the batteries are seated correctly to initiate the charging process.

What to consider before purchase

• Verify that your device is compatible with 9V rechargeable NiMH batteries.
• Ensure you have access to a charger capable of handling 9V NiMH cells.
• Consider the total number of devices you need to power to determine if additional packs are required.

Usage recommendations

For optimal battery health, avoid deep discharging the batteries completely whenever possible. Store them in a cool, dry place when not in use for extended periods to maintain their capacity and longevity. Always use a high-quality charger designed for NiMH batteries to prevent overcharging.
