How Are NiCd Batteries Charged, Used And Applied?

After lead-acid battery being invented in 1859 by Gaston Plante, rechargeable batteries came into existence also called the secondary cell, storage battery or an accumulator. They are generally costlier than disposable batteries but can be termed as value for money since they have a lower environmental impact. Many of the combinations of electrodes and electrolytes that are used to make these rechargeable batteries are Nickel-Cadmium (NiCd), Nickel Metal Hydride (NiMH), Lithium-ion (Li-ion) and Lead-Acid.

History of NiCd battery

Nickel-Cadmium batteries came as a counterpart of Lead-acid batteries in 1899 when Waldemar Jungner invented this less physically and chemically vigorous combination. Instead of using acid, alkaline electrolytes were used. They also have a better energy density than lead-acid.

While Jungener’s work remained to be unknown in the United States for many years and in 1902, Thomas Edison patented it as he adapted the battery design to introduce the nickel-battery in the US.

How to charge a Nickel-Cadmium battery

  • Nickel-Cadmium batteries are charged according to their manufacturing and design.
  • They are charged with a voltage to 1.55V/cell which is then reduced 0.1C and is charged until the voltage reaches 1.55V/cell again.
  • Higher power voltage can be used while charging since the chemical reaction that occurs while charging is heat-absorbing instead of heat producing.


Features and advantages

Nickel-Cadmium batteries have many distinguished features and benefits to the user which can be explained as follows:

-NiCd batteries are well known for delivering high power output because the internal resistance is lower in comparison to the typical lead-acidic batteries.

– Lower internal resistance makes the battery capable of discharging as well as absorbing power at a faster rate.

-Since high power absorption is possible without overheating while charging of the battery, quick recharge times become possible.

– Excellent choice for all types of cordless power tools, NiCd batteries provides a high amount of power for the entire time of its usage. The counterparts of NiCd batteries do not provide such kind of constant power to the tool and declines gradually with use.

Applications of NiCd batteries

NiCd batteries come in various different sizes.
They can be used individually or can be assembled in packs using two or three sealed batteries.
They can easily be used in the place of disposable cells.
– Small battery cells are used in electronics, toys, solar lights etc.
– Miniature button cells are used in flashlights, torches, toys, computer-memory standby etc.
– These batteries are one of the best choices for cordless equipment like telephone, non-electric lamps, lights etc.
– Bigger cells are used for standby power and electric vehicles.


It could easily be said in the conclusion that NiCd batteries have some exceptional qualities and is a tried and tested choice for usage.
