Nickel cadmium batteries have been around for more than fifty years and they're still one of the best rechargeable batteries around. In 1899 Waldemar Jungner invented the NiCad (NiCad is short for a nickel cadmium battery). A NiCad is complied of rolled up layers of nickel with cadmium between the layers. NiCads are used to generate many appliances such as calculators, digital cameras, cassette players, radios, portable hand tools and shavers. They come in battery sizes that vary from AAA to D.
Purchasing NiCads may be a bit pricey compared to other rechargeable batteries, but they're more reliable and efficient than others. NiCads don't damage as easily as lithium ion batteries (another type of rechargeable battery) and they have a higher number of charge and discharge cycles than other rechargeable batteries. NiCads are usually more preferable than others because of its higher energy density. A small, light weight NiCad could have the same energy capacity as a heavy lead-acid battery. The weight of a battery might be considered when used in a cellular phone or in other portable devices. Due to the technological advances in handheld and portable devices, NiCads have been used more often and have become popular amongst these devices.
Another great quality about NiCads is that its voltage is relatively stable when it discharges. The voltage of a NiCad range from 1.2 to 1.25 volts compared to alkaline non-rechargeable batteries with a 1.5 voltage. With a steady voltage, the performance of an application will not change. In alkaline batteries, as the charge drops, the voltage drops, which may change the performance of a device and led to unsatisfied consumers. NiCads have many appealing qualities and many advantages and can be reused for a long time if handled with proper care.
