DUSLAN Powerizer D 10000mAh NiMH 1.2V 8-pack

Eight-Cell Pack for D-Cell Devices

This eight-pack supplies 10000 mAh NiMH cells at 1.2 V for any device that takes standard D batteries. The Powerizer chemistry eliminates memory effect so partial recharges do not reduce usable capacity. Each cell arrives pre-charged and holds roughly 85 percent of its energy after a year in storage. Replacements are simple because the form factor matches every product designed for D-size primaries.

Steady Output Through Extended Use

NiMH chemistry maintains a flatter voltage curve than alkaline alternatives, so high-drain gear such as large flashlights or portable radios keeps running at consistent brightness or volume. The cells support a high discharge rate without rapid voltage sag, and they can be recharged up to 1000 cycles for repeated heavy use. Low self-discharge means a charged pack left in a kit is still ready months later. Sustained loads do not trigger the sudden capacity collapse common with disposable chemistries.

Drop-In Upgrade from Disposable D Cells

Swapping alkaline D cells for this pack removes the recurring cost and waste of single-use batteries in any D-powered device. The jump is worth it when a device sees frequent or high-current use that drains primaries in hours rather than weeks. Infrequent low-drain applications such as backup clocks or rarely used remotes will not recoup the investment as quickly. Users who need a different voltage or a smaller form factor should look elsewhere.
