Custom Lithium ion Battery Pack

Rebuild NiCad battery pack with lithium-reviving, charger, and replacement

APR 29, 2021   Pageview:52

NiCad batteries have been prevalent for many years. Despite this, they were recently replaced by new lithium-ion battery technology. These batteries are smaller, require less maintenance, and are more environmentally friendly than NiCad batteries. Although lithium-ion and NiCd batteries are similar in their chemical composition, applications, environmental impact, and costs. In the next paragraph, we will consider whether NiCad batteries can be revived.

Can NiCad batteries be revived?

NiCad batteries are mostly found in cordless power tool brands such as Makita, Dewalt, Bosch, Hitachi, Porter-Cable, Ryobi, and black and Decker, etc. They are also used in saws, cordless drills, flashlights, hammer drills, jigsaws, and demolition hammers. The kind of batteries used in these devices fails naturally if it is not subjected to regular maintenance. Battery manufacturers don't tell you the proper way to maintain your batteries because they prefer you buy a new one every few years. The Nicd cell is very dependable and has been confirmed to be very effective for several years.

That is one reason they are used by so many tool manufacturers. When they are properly maintained, these batteries can last for years. Another good thing about NiCad batteries is that they can be revived. Reviving the NiCad battery is a simple process and has a 98 percent success rate with thousands of units sold all over. It is a very easy process if you know what to do.

The NiCad batteries won't last forever. Depending on the maker, under flawless conditions, you can get up to a thousand charges and discharges. However we are not in a perfect world, so it is possible for things to go wrong with the batteries, the common problems you may experience with NiCad batteries are dendritic shorting and cell Reversal. Though, both of these problems can be avoided by taking good care of the batteries.

Cell Reversal is a situation where a single cell in the battery discharges before the others. This will lead to reverse charging, which can really damage the battery. The process will significantly reduce the battery life. And Dendritic Shorting takes place when the battery is not used regularly. What happens is that the Dentrites which are conductive crystals can form between the electrodes.

Rechargeable batteries don't last forever. In fact, most of them have a specific life expectancy, stated as the number of charge cycles they are expected to go through before they need to be replaced. However, you can revive the life of your rechargeable batteries with this service. Reviving NiCad batteries can save you money and also help the environment by keeping them out of the landfill for longer.

Can a NiCad charger charge lithium-ion batteries?

The direct answer to this question is no. This is because the NiCad battery voltage is 1.2V, and the lithium battery charging voltage is 3.7V. The NiCad battery charging voltage is approximately 1.45 V and the lithium battery charger is approximately 4.2V. Using a NiCad charger to charge the lithium battery will only not charges the battery, but can also cause the lithium battery to discharge and damage the battery. Both batteries are made of two different materials with unlike nominal voltage, charge-discharge characteristics, and working principle.

It can be very dangerous to charge your Lithium battery with a NiCad charger. Even non-professionals will advise against doing this as it is very risky. Charging lithium batteries with a NiCad charger can cause avoidable fireworks and you won’t want to try that at home unless your belongings are fully insured. Lithium battery also referred to as Li-ion batteries, are usually smaller in size and they require less maintenance, they are considered safer to use than NiCad batteries. The NiCad batteries are harmful to the environment, which is why lithium-ion batteries are used more often than NiCad batteries. Even though they may be similar, they both differ in cost, chemical composition, impact on the environment, and also applications.

Can you replace your NICD batteries with lithium?

It is very possible to replace NiCD batteries with lithium batteries as long as the batteries that replace them have the same voltage as NiCD batteries and can fit in the device. The important thing is that the batteries have the same technology. Therefore, the performance does not change regardless of the battery technology you use. Lithium batteries are usually smaller in size and come with a higher capacity than NiCD batteries. Mostly, you may need to replace each 3 NiCD batteries with one lithium battery to get the same power. 

When replacing your NICD batteries with lithium batteries make sure you disassemble the battery very carefully. Because most packages are sealed with glue and you may need to apply a lot of force to loosen them. Examine the voltage of the batteries you are replacing and make sure your lithium alternatives have the same voltage as well. This is because replacing the batteries with the wrong voltage will greatly affect the performance or damage the circuitry of your device. The only difference will be how long the battery will last on a single charge. The following are some of the benefits you will gain from replacing your NICD batteries with lithium batteries.

They have no memory effect. The memory effect occurs when the battery cannot clearly recall the maximum charge and discharge points. This results in improper battery percentages.

Lithium-ion batteries can withstand wide operating temperatures compared to NiCD batteries. Meaning if you plan to operate at temperatures well above room temperature, you will be much safer using devices that contain lithium-ion batteries than NiCD.

Lithium-ion batteries are lighter and smaller than NiCD batteries because of their high energy density. This will ultimately make your device lighter than when using NiCD batteries.

Lithium-ion batteries have a lower propensity for self-discharge. Meaning you can store the batteries for a very long time and not lose a large amount of charge.

And lastly, don’t forget that notwithstanding the above-mentioned benefits, you will need to pay nearly double the amount if you would like to replace your NiCD batteries with lithium-ion batteries, even though the deal can pay off in the long run.
