What is the Difference Between NiMH and NiCd Batteries?

NiCd batteries are a common type of battery that goes back to the days of old. Their life spans are brief, typically ranging from 20 to 40 cycles depending on the quality. They store extra energy efficiently, but cannot hold their charge for long periods of time. NiMH batteries have a higher energy density than NiCd batteries, which means that they will have a longer life span and can hold their charge longer than typical NiCd batteries.

NiMH and NiCd batteries have a different charging cycle. NiMH batteries are charged at 1 amp for a short time, which causes them to reach as high as 100% capacity. NiCD batteries are charged at 0.8 amps for a long period of time which causes them to reach 80% capacity.

Nickel-metal hydride is the chemistry used in many electric power tools and batteries. Nickel-cadmium was the key element in electric powered cars from 1956-1998 but is due to toxic poisoning, isn’t safe for use. Nickel metal hydride batteries were introduced to replace cadmium with lithium, which eliminates cadmium’s toxic properties.

How Does an NiMH Battery Charge?

Nickel-Metal Hydride (NiMH) battery is preferable because it can last longer between charges than the average disposable batteries that previous models used. The conventional nickel-cadmium battery requires a more frequent charge than NiMH batteries. An NiMH battery needs to be recharged after each use, so it retains less energy than the rechargeable one from previous models.

Here are the steps to charge an NiMH battery:
1) At the beginning of your charging cycle, connect the battery charger to a power outlet and turn it on.
2) Set the battery charger to charge at a specific voltage for only one or two hours, or half that time for smaller batteries.
3) Attach the plastic clamps onto both sides of the battery and then attach one fully charged Nickel Metal Hydride (NiMH) storage battery to each red cord.
4) Connect leads A and B into an electrical device that requires the use of an batter.
5) Leave A and B connected and then let your electrical devices run throughout the night so long as you have them plugged in

NiMH batteries are designed with a high voltage that is meant to slowly charge them. They typically charge slowly but have a higher energy density per weight than batteries with less voltage. The battery can be charged in 2 ways: by leaving it in an NiMH charger or by charging (or discharging) it through an inverter

NiCd vs NiMH: Which Type of Battery is Better for Your Project?

Ni-Cad batteries, which is the acronym for Nickel Cadmium, was the original type of rechargeable battery. Comparing them with NiMH, or nickel metal hydride as it is using in current times, Ni-Cad had a much higher energy density and were lighter in weight. However, Ni-Cad batteries were susceptible to efficiency loss during capacity decay due to self-discharging. Compared with this drawback, one of the advantages that comes with NiMH batteries can be light weight – they are up to 60% lighter than their predecessors.

There is an ongoing, heated debate about which type of battery is best for your project. Some people argue that NiCd batteries are less expensive and have longer lasting power than Nickel-Mh (NiMH) batteries. However, others feel that the round peg in a square hole syndrome is applicable to this discussion, such as larger or fatter charges equaling greater annual days usage.

There are a few different types of rechargeable batteries, but three of the more commonly used today are nickel-cadmium (NiCd), nickel metal-hydride (NiMH), and lithium-ion (Li-ion). More people often confuse which battery type is better than another. For example, between the two, they have been known to perform similarly in terms of working with similar cycle life times. However, lifetime has been found to drag down the performance of NiCd batteries versus NiMH batteries.


The Ecotality LR44 battery is perfect for a Texas electricity needs. These batteries have 58 amp hours of capacity and can be charged from 4 to 5 times per day.

The electrical age has taken a new turn into the next millennium with the advent of lithium ion. But few know that is still only in its infancy and we haven’t even begun to understand how it can work. In simplest terms, battery cells are made up of three parts: an anode, cathode, and electrolytes. The manganese dioxide cathode produces oxygen during oxidation processes, which is used by the lithium ions to travel to and from the anode. The electrolyte breaks down chemicals into ions, which allows these charges to move around easily.

It is interesting to note that batteries are a basic need of pretty much every device on the market now. It’s a simple fact that an 18650 battery is usually equivalent to one unit of LR44 batteries.
