Rechargeable Battery Telekom AAA 1.2V 850mAh, Nickel‑Metal Hydride

Rechargeable Telekom AAA 1.2V 850mAh Nickel‑Metal Hydride battery is a single-cell power source designed for everyday portable electronics. With a nominal voltage of 1.2V and 850mAh capacity, this NiMH AAA cell provides repeatable recharging cycles and reliable power for small devices. Its compact AAA format fits standard battery compartments and serves as a reusable alternative to disposable alkaline cells, helping to lower long-term operating cost and reduce waste.

Advantages

This NiMH rechargeable cell offers stable output suitable for low- to moderate-drain devices, with capacity that balances size and runtime. The 850mAh rating delivers extended use between charges compared with lower-capacity AAA rechargeables, while the NiMH chemistry is tolerant of repeated charge/discharge cycles. The AAA size and standard polarity make the cell compatible with a wide range of consumer electronics. As a rechargeable option, it reduces the frequency of battery replacement and associated environmental impact compared to single‑use cells.

Suitable for

• Remote controls and TV peripherals
• Small toys and handheld games
• Clocks, thermometers and small household devices
• Wireless computer mice and keyboards with AAA compartments
• Portable LED lights and personal care devices

Key specifications

• Cell type: Nickel‑Metal Hydride (NiMH)
• Nominal voltage: 1.2 V
• Capacity: 850 mAh
• Size: AAA (also called R03)
• Form factor: cylindrical single cell

How to use

Insert the AAA cell into the device following the polarity markings (+ and −) in the battery compartment. Use a compatible NiMH battery charger that supports AAA cells and follow the charger's instructions for charging current and duration. Allow the battery to reach room temperature before charging if it has been stored in cold conditions. For best results, avoid mixing new and used batteries in the same device and do not mix rechargeable and disposable cells together.

Recommendations

Charge the cell with a charger designed for NiMH chemistry and select an appropriate charge current; slow or smart chargers prolong battery life. Store cells in a cool, dry place and avoid prolonged exposure to high temperatures. If a device will be unused for extended periods, remove the battery to prevent leakage and self-discharge effects.
