DUSLAN D NiMH standard battery 4000 mAh 1.2 V

D NiMH Battery 4000 mAh

This D-size nickel-metal hydride cell delivers 4000 mAh at 1.2 V for devices that require standard D batteries. It suits users who regularly power high-drain electronics such as torches, toys or portable audio equipment and want a reusable alternative to single-use alkaline cells. The chemistry avoids memory effect so partial recharges do not reduce usable capacity over time.

Recharges up to 1000 Cycles

Each cell can be recharged up to 1000 times, replacing hundreds of disposable alkaline batteries and lowering long-term cost. The lack of memory effect means the battery can be topped up at any state of charge without degrading its full capacity. This makes it practical for households or workplaces that cycle batteries frequently.

Simple drop-in replacement

The battery fits any product designed for D-size cells without adapters or modifications. Installation is as straightforward as inserting a standard alkaline cell, observing the correct polarity markings. The only common issue arises if a charger not designed for NiMH chemistry is used, which can prevent the cells from reaching full capacity or shorten their service life.
