VOLTCRAFT Mono (D) Li-Ion akku 6000 mAh 1,5 V, 2 kpl:n pakkaus USB-C-lataustoiminnolla (VC-17275580)

Unlike standard D-cell batteries that lose voltage as they discharge, these VOLTCRAFT Mono (D) Li-Ion cells deliver a constant 1.5 V output from full charge to empty. Each battery integrates a USB-C port, so you can recharge them anywhere without a dedicated charger. The 6000 mAh capacity and up to 1200 charge cycles make them a cost-effective replacement for disposable batteries in high-drain devices like flashlights, toys, and portable radios.

Highlights

• Constant 1.5 V output ensures consistent performance until fully depleted
• Integrated USB-C charging port on each battery – no separate charger needed
• High 6000 mAh capacity for long runtime in demanding devices
• Up to 1200 charge cycles reduce waste and long-term cost
• Built-in protection against overcharge, over-discharge, and short circuit
• LED indicator shows charging status at a glance

In daily use

Pop these into any device that takes D batteries and enjoy reliable power without the voltage sag typical of NiMH or alkaline cells. When they run low, simply plug a USB-C cable into the top of each battery – the LED glows red while charging and turns green when full. A full charge takes about 6 hours with a 1 A USB power source. The stable voltage is especially beneficial for motorised toys, high-power torches, and medical devices that require consistent output.
