When you need the longest life possible from your rechargeable D batteries, this is the right choice. These NiMH "D" cells from the world leader in battery technology provide stable output for much longer than standard rechargeable batteries. These premium batteries are intended for maximum output under constant use and multiple fast charges. They're ideal for applications with high energy requirements, such as photo flash units. Because they're capable of fast recharge up to 1000 times, you'll eliminate the need to buy replacements for months or perhaps years. When it's time to replace them, you can do so with less ecological impact, since the materials in these batteries are almost completely recyclable.
These NiMH batteries will safely replace alkaline or NiCd cells in almost any equipment that uses D batteries. Unlike some manufacturers who construct D cells by inserting a AA cell inside a larger package, Ansmann makes use of the entire volume of the case. This manufacturing process combined with German technology that allows a higher density charge results in a capacity that's double most competitors' batteries and triple the amount of some. NiMH technology also minimises the memory effect found in many NiCd batteries, which required complete discharging to retain the full capacity of the cell. Compared to similar lithium-based rechargeable batteries, these require no special charger and don't pose the risk of damage to some devices.
These batteries can save you literally hundreds of pounds per year over conventional alkaline batteries and will provide better performance much longer than their "nicad" counterparts. In fact, they're reliable enough to come with a 2-year warranty. They're better for the consumer because they don't contain dangerous elements like cadmium, and they're better for the environment in many ways. With all that considered, why would you buy anything else for your devices that require high-output D batteries?
