Do you who use walkie-talkies know the difference between lithium-ion and nickel-cadmium batteries?
By understanding the difference between lithium-ion and nickel-cadmium batteries, you will be able to make more informed purchasing decisions, and you can also use these batteries more effectively in existing equipment. This saves money.
In the past few years, people think that nickel-cadmium batteries (NiCad) are the best batteries available for wireless devices. However, lithium ion batteries (Li-ion) have been taken over. Compared with nickel-cadmium batteries, lithium-ion batteries are smaller, require less maintenance and are safer for the environment.
Due to the different chemical composition of the battery, the maintenance requirements, size and weight, environmental impact and cost of the battery are also different. We will test them at all these points.
Ni-Cd vs. Lithium-Ion Battery-Operation, Battery Maintenance and Service Life
Two batteries with the same voltage will provide you with the same amount of power. However, how long it will provide power is another question entirely. After a charge, the performance of lithium-ion batteries will be better than NiCad. Another major advantage of lithium-ion batteries is that they hardly self-discharge and can be stored for months without losing charge. This means that you can buy them in bulk and save money without worrying about them becoming unusable in the future.
One problem with NiCad batteries is that they have a "memory effect", which means the battery remembers where you were in the charging cycle when you started charging. This causes the voltage to drop to this point. Therefore, you should wait until the Ni-Cd battery is completely discharged before charging.
Lithium-ion batteries do not have this problem and can be used in a wider temperature range. However, they are more fragile and require circuit protection for optimal performance. NiCad batteries will last 1,000 or more before they lose capacity, while lithium-ion batteries are less.
Lithium-ion batteries and nickel-cadmium batteries-size, weight and overall performance
Generally, lithium-ion batteries are lighter and smaller than NiCad batteries, so they are particularly suitable for use in smaller portable devices with similar performance.
Nickel-cadmium batteries and lithium-ion batteries-environmental impact
Nickel-cadmium is considered a hazardous waste, so even if you use rechargeable batteries, when you need to replace these batteries, you will pay a huge environmental cost. These chemicals will eventually ooze out, so they should not be thrown away with regular waste, but should be recycled in a licensed factory. Lithium-ion batteries do not contain harmful toxins.
The cost of nickel-cadmium batteries and lithium-ion batteries
You will find that lithium-ion batteries are usually 2 to 3 times more expensive than nickel-cadmium batteries. However, their size and weight, the ability to store lithium-ion batteries for a long time, and other factors such as eco-friendly construction may exceed the increased cost.
No matter which battery you end up using, the information and useful tips in this article will help you make the most of them.
