Today’s consumer marketplace offers a considerable number of high-demand electronic devices, such as DSLR cameras and camcorders. Until the advent of recent technological advances, rechargeable batteries were not practical for use in many of these devices, as their low capacities meant having to recharge them too often. All of this began to change with the development of NiMH (nickel/metal hydride technology) and other significant breakthroughs that allowed manufacturers to offer rechargeable batteries with very high capacities. Today’s NiMH technology offers rechargeable batteries with high capacities that exceed the performance of their disposable counterparts.
For instance, AA rechargeable cells are now available with a capacity of 2500mAh and higher. While an alkaline AA battery may be roughly rated at 3000mAh capacity, it’s important to note that the voltage of the alkaline battery will drop steadily as it discharges, rendering it unusable in many devices more quickly. The high-capacity NiMh battery will maintain a more stable output voltage until the end of its cycle, making it a better choice for high-demand use, and it is reusable up to thousands of times!

Photographers, videographers, surveyors, security personnel and other professionals or serious hobbyists may want to consider these high capacity rechargeable batteries as an alternative to single-use batteries or standard capacity rechargeable cells.
