Batteries have been around for decades, and have been essential power-providers for numerous and varied gadgets, from toys to work tools. They have also evolved over time, with alkaline and lithium being the most popular.

Of course, with the on-set of the green revolution, rechargeable batteries are now preferred for use in new gizmo releases. Rechargeable batteries are reusable so you can save on repeated purchases. One of the best batteries of this type are hybrid Nickel-Metal Hydride (Ni-MH) rechargeable batteries. I tried these out after a long run of frustrations on completely drained disposable alkaline. Ni-MH batteries are great replacements! They can be used for both battery-draining and slow-draining gadgets. These batteries can be purchased already in full charge so you can use right out of the packaging. With a capacity to sustain charges for over months, these batteries have long shelf-life and are ideal for emergency kits. They can be used with a range of gadgets and uses, from cameras to portable lights and even complex toys. They are highly commended for efficiency in power use as well as money-wise.

Top brands of Ni-MH batteries include Sanyo’s Eneloop, E8GE1000 and Uniross’ Hybrio. Personally, I use Rayovac’s I-C3 Ni-MH batteries for my photography stint. It’s perfect for on-the-go jobs because of the 15-minute recharging time. Even with cameras that drain batteries after long a few hours of use, the I-C3 is a reliable battery. Rechargeable Ni-MH batteries are definitely efficient, convenient, and excellent – great purchase for your gadget needs!
