AAA Rechargeable Batteries

Frequently Asked Questions about AAA Rechargeable Batteries

What is the difference between NiCd and NiMH Batteries?
NiCd refers to Nickel Cadmium and NiMH refers to Nickel-metal Hydride. NiMH batteries are the superior battery as they have higher capacity, no memory effects, and are environmentally friendly. Since NiMH batteries have twice the capacity of NiCd batteries, they'll have much longer run time (more hours of music or more pictures) before needing recharged.

Are NiMH rechargeable batteries better for some applications over alkaline batteries?
For high-drain electronics, like digital cameras, NiMH AAA rechargeable batteries will run much longer than alkaline batteries. You might even see a three to four times increase on a single charge. Alkaline batteries are better suited for lower drain applications like remote controls and clocks.

Why are they called "AAA" rechargeable batteries?
AAA is a common name given to batteries that's approximately 44.5 mm (1.75 in.) in length and 10.5 mm (0.4 in.) in diameter. AAA batteries can be given more specific designations. For example, the IEC name for AAA NiMH batteries is HR03.
