Instructions and FAQs on lithium ion power tool battery

What is a power tool batteries

Electric rechargeable tools became a must have for handy workers and DIY lovers. Screwing or drilling tasks are done easier and faster without the need of cables and plugs everywhere. Brands are competing to improve the specs and use of their tool where comes the need of improving the batteries as they are the main part. The goal is to have long life, fast charging and high capacity.

These tools are usually equipped with three main types of batteries: Nickle cadmium (NiCd), Nickle metal hydride (NiMH), and lithium ion (Li-Ion).
Even though all three technologies mentioned above are designed for the same reason, there are major diffrences between them. If you are interested in buying a battery and you are confused, the following part is for you.

What is a power tool battery

Nickle cadmium NiCd batteries

Among all the technologies noted above, this is the oldest one. NiCd batteries are reliable and known for their toughness. These batteries perform better than the newer type metal hydride and the lithium-ion batteries when it comes to extreme conditions:

they are more shock resistant and can operate safely at a temperature range of -40 ~60° C. These specs keep them available until today and standing against competition, but they have serious memory effects and they are harmful to the environment.

Nickle metal hydride NiMH batteries

These are a new generation of the NiCd batteries but they are more expensive. However, it’s a price to pay for the specs this technology offers: lighter weight, the energy density is about twice that of NiCd batteries, and the most important feature is their reduced impact on the environment. They should be stored in the proper conditions to maintain them. Their temperature operating range is -20-6°C -4-140°F so not so sensitive to heat.

Lithium ion batteries

The Lithium-ion Batteries are the latest technology and the most recent of all 3. Even though they’re also expensive but their high energy density, light-weight and high capacity make them the best option. Their main problem is the temperature sensitivity during use or charge.

They have long life time, about 4000 cycles, and as it is becoming the most important criteria of evaluating products lithium-ion batteries have less impact on the environment than all other types.

Lithium-ion are the most promising type, as they are the most recent a lot of researches are focusing on developing them to meet the future requirements and improve their specs. Almost all recent tools are equipped with lithium-ion batteries.

What factors should be considered while buying power tool batteries

Life cycle: usually referred as the number of charge cycles the battery can withstand. For example, the NiCd could live up to 1000 cycles.

Self-discharge: Rechargeable batteries lose their charge even when not in use but this factor varies from one type to another. Professionals don’t keep their tools stored for long, so this doesn’t make a huge difference for them but it a factor that occasional user should consider. Litium-ion batteries are known by their low self-discharge rates.

Voltage: The voltage of batteries is mainly related to the tool their mounted on, relatively high performance and heavy-duty ones will require more voltage. The range goes from 7v for light duty to 36v for heavy duty.

Capacity: The capacity or run-time, is the duration the tool can operate between charges. It’s expressed by the delivered Amperes per hour “Ah”.

Memory effect : when the battery is frequently recharged without being completely discharged it kind of creates a memory of that and when it’s reused it provides electricity adopting the same cycle of recharge making it drop performance.

Lithium-ion batteries have no memory effect, and usually discharge to only 20~30% left to charge, which is beneficial to prolong the life of lithium batteries

How to choose power tool battery chargers

We can’t speak about batteries and not mention chargers, choosing the appropriate one is absolutely important for sustainability. For lithium-ion batteries, their chargers are specially designed for lithium batteries and should be selected very carefully to protect them. In most cases fake fast chargers will only kill the lithium-ion battery so it is recommended to keep it recharge without any attempt to speed the operation to avoid them overheat.

Storing power tool batteries

All batteries should be kept away from sunlight, temperature and humidity. It is important to keep the place ventilated to preserve them. In terms of storage, Normally, ambient room temperature is enough to maintain lithium-ion batteries. To avoid overheating it’s recommended to remove the battery from the charger once it’s completely charged.

Which battery type is best for power tools

The battery is what keeps the tool operating wireless, so it could be considered as the main component that should be chosen carefully. Like mentioned above, each of the three types has its Pros and Cons but to make a good decision you should consider the price, the endurance and the capacity.

If you work for long periods lithium-ion batteries are your best choice because they are known for their long run-time and light-weight so holding the tool for long time won’t be a problem.

In case of outdoors works in which there is a huge risk of sun exposure, the tough Nickle Cadmium are the best choice as they can resist to high temperature. But the memory effect of Nickle Cadmium can give you a headache.

Lithium-ion batteries safe use

For the last decade this new technology became more popular among power tool batteries manufacturers. Thanks to their improved capacity and extremely light weight lithium-ion batteries are the best option for many users.

Their materials are less toxic compared to previous models, they may be dangerous in case of miss handling. Lithium-ion batteries are known to be extremely sensitive to heat that’s the reason they should be kept in dry cool places.

If you work for long periods lithium-ion batteries are your best choice

As a user you should always read the manufacturer’s guide carefully, different lithium batteries have their own operating temperature range. The batteries could make chemical reaction if a liquid such as water is in direct contact with the internal cells which in extreme cases could lead to explosion. So, you can’t disassemble the battery by yourself.

After charging or in case of non-uses it’s recommended to disconnect the batteries to avoid any potential overheat because in this case Lithium-ion batteries are likely to catch fire or explode. Make sure to use the original charger to maintain the lifetime of your battery.

So, for a safe use just follow instruction and don’t try any weird tricks from the internet at home.

How to dispose of old power tool batteries

The mentioned 3 battery types are designed to be recycled or treated to avoid their negative impact on the environment. Being instable elements, batteries of all kinds should never be thrown in nature or with ordinary garbage because they contain hazardous materials such as cadmium which could contaminate water or soil if thrown in nature.

Worldwide there are special containers or even centers where you can dispose of your old batteries also some stores could accept them for recycling purposes. The lithium-ion ones are the most environment-friendly batteries they could be easily recycled.

To avoid any kind of accidents don’t try to manipulate or open a dead battery on your own at home it’s a dangerous operation that should be performed only by professionals.

Also, you should never throw an old battery in fire as it may explode due to the heat. Some experts recommend covering the connectors with tips before getting rid of a battery in case not sure it’s fully discharged.

The future of power tool batteries

Power tools have no wires and could operate four hours without needing a fix source of energy. This feature, makes them the best choice for workers as they reduce their need for plugs and that give them more mobility in work.

The high demand and the developments lead to the need of more powerful batteries for the bigger tools. The lithium-ion batteries are the best option that meets all requirement of the industry with latest researches giving them the capacity to recharge in few minutes and last longer.

But in the field of high-tech there are always new invention like the carbon-ion cells. These batteries use ionic electrolytes and nano carbon to store energy. These batteries will have the capacity to store more energy operate at high voltages and the most important charge very fast.

How do you recondition a power tool batteries

When a battery life cycle seems comes to its end, it doesn’t mean you should get rid of it. There are ways and tricks to save the battery and your money. Power tool batteries are very easy to recondition without the need for a huge knowledge about chemics or mechanics.

The main thing to know about reconditioning batteries is the reasons they need to be reconditioned. Batteries die because of the memory effect or crystal formation, to deal with those problems and bring your battery back to life, you can follow some simple steps.

Memory effect
The main reason for this problem is not using the battery to its full potential, this leads to a loss of capacity. The process of fixing this problem is very easy and simple:
– Charge the power tool completely
– Unplug the charger, turn it on, and discharge all power.
– Charge it again
– Repeat this process a few times to reset the battery.

Crystal formation
This is due to the formation of small crystals on the anode and cathode inside the battery.
This phenomenon reduces to contact surface between electrodes and electrolytes, and it’s caused by overcharging.
The easiest way to deal with the problem is using a battery conditioner. If you don’t have one, deep discharge the battery. Each cell needs to discharge below 1V. Recharge it again and use it. Avoid manually discharging the battery too many times.


To sum it up, there are three types of power tool batteries, each has its own pros and cons and could be chosen to fit user’s requirements like endurance and capacity. Batteries should be maintained in the proper ways to improve their lifetime and when they’re not useful there are safe ways to get rid of them.
