Shortest charge time, even after extended storage or at low temperatures.Įasy to charge and handles overcharges and rapid charging with minimal stress. Wide selection of sizes and performance options. Most economical battery type in terms of operational cost per cycle.
High number of charge and discharge cycles with proper maintenance.

This requires a periodic full discharge cycle to offset the battery’s loss of capacity over time due to memory effect. In simple terms, memory effect is a condition in which a battery seems to remember the previous energy delivered and fails to deliver beyond it. The airline industry, for example, continues to turn to Ni-Cd.īoth Ni-Cd and the newer Ni-MH, suffer from a ‘memory effect’. Nickel cadmium batteries are not a model for environmental friendliness and are now largely designated to commercial applications. But because they are composed of cadmium and other toxic metals, they have presented disposal issues. By modern standards, they continue to be considered durable batteries that work well in rigorous applications where long life, high discharge rate, and economical pricing are the priorities. The ruggedness of the Ni-Cd made it among the more robust and forgiving battery of its time.

Ni-Cd batteries continued to be a staple battery for portable devices until the 1990s. In the late 1980s, Ni-Cd batteries made an impact with models that packed more active material in the cell which enabled capacities of up to 60 percent higher than the standard Ni-Cd however, these ultra-high-capacity Ni-Cd batteries suffered higher internal resistance and reduced cycle count compared to the standard versions.

Nickel-cadmium grew to be the preferred battery choice for biomedical and emergency medical equipment, professional video cameras, two-way radios, power tools, and a variety of other devices. By 1947, Ni-Cd was capable of absorbing the gases generated during charge, propelling the technology to the sealed Ni-Cd battery. In 1932, advancements were made to deposit the active materials inside a porous nickel-plated electrode. Despite the cost of materials and slow development, the Ni-Cd offered several advantages over lead-acid batteries. Ni-MH batteries, in fact, inherited many of the characteristics of Ni-Cd batteries that they came to replace.Īs one of the older battery technologies in use, Nickel-cadmium batteries were invented in 1899 by Waldemar Jungner during a time when the only other rechargeable power in active use was the lead-acid battery. Despite their differences, the two systems share similarities. Since the 1940s, portable devices were often powered by nickel-cadmium batteries, but this chemistry was supplanted by the rise of the nickel metal hydride battery in the nineties, coinciding with environmental concerns and the ability to better meet various applications. Nickel-cadmium (Ni-Cd) and nickel metal hydride (Ni-MH) batteries are secondary batteries, which in simple terms, means that they are rechargeable, as opposed to single-use, primary batteries (e.g., alkaline batteries, silver-oxide watch batteries, and others).
Nickel-based batteries account for a one of the larger battery categories used in both the consumer and commercial sectors.
