what to do with old power tool batteries

Your cordless drill tin can deliver good performance for many years if you utilize it and treat information technology with care. But your drill bombardment is likely to die out much before that, making your cordless drill virtually useless. Merely if yous know the correct bombardment reconditioning methods, yous can make the battery work like new for a really long fourth dimension.

Somewhen all drill batteries lose their capacity to concur a charge and evangelize optimal power. But reconditioning tin revive and rejuvenate batteries that you thought were dead. What you have to do depends a lot on the chemical science of the battery.

Never buy another replacement battery.

Acquire how to bring back any bombardment back to life and and make it work like new again.

This is how you practice information technology.

Newer cordless drills might come with Lithium-ion batteries, but NiMh is still a pop choice because information technology keeps the over all cost of tool low. Lithium-ion (Li-ion) batteries are more expensive.

Nickel Cadmium (Ni Cad) and NiMh are two common kinds of batteries you lot will find in cordless drills.

The two master reasons for Ni based drill batteries dying out are:

1. Memory effect
2. Crystal formation

Reconditioning to Remove Retention Issue

You've probably heard term "Memory Effect". "Memory Effect is the phenomenon that makes a battery lose its capacity to deliver a full charge. It happens more than with NiCd batteries much less with NiMh and none whatsoever with Li-ion. In other words but the Nickel based batteries (Ni) suffer from retentivity effect."

When a bombardment is repeatedly partially discharged, it only remembers the last corporeality of accuse information technology held. If more ability is demanded the adjacent time, it shuts down completely as if to protest against the extra work. That in short is the memory effect.

The simplest way to remove a retentiveness effect from a cordless drill is to go far go through a reconditioning accuse cycle.

In social club to do this:

1. Charge the drill fully.
2. Discharge it completely nether zero load, i.e. permit the drill to run on its own till it stops. People usually achieve this by taping the trigger in an ON position.
3. Charge the bombardment fully again.

If this procedure improves the functioning of the bombardment then repeat it merely after at least 1 month.

Circumspection: Do non try this with a battery that'due south working properly already. You lot should charge a commonly performance battery whenever it loses substantial power to function. Practice the deep discharge described above only when you are trying to recondition a battery that doesn't work properly anymore.

Important Note: Check the user manual of the cordless drill. Your charger may exist equipped with the ability to deep charge/ recondition the battery. Follow the instructions, if whatever, earlier you try this.

If this doesn't work, it may be time to buy a new bombardment.

Reconditioning Battery To Remove Crystallisation

NiMh batteries are less prone to the memory effect. In fact many tool manufactures will tell you that their cordless drill is completely free from this consequence. This is somewhat true. Retentiveness event is more mutual in low drain devices like cordless phones. A cordless drill draws a lot of power, and in bursts.

Modern batteries endure a lot less from retentivity effect. However batteries in cordless drills notwithstanding lose their ability to power the tool. It might not be the memory consequence but due to the chemical reaction taking place inside the battery every time y'all charge and discharge it. Newer Nickel based batteries might be less prone to memory upshot but they do suffer from "crystalline germination."

Crystalline formation refers to the condition when crystals course on the anode and cathode within the battery, reducing the surface that comes in contact with the electrolyte. This can severely reduce the current flowing between the terminals of the bombardment and hence its effective power.

Crystalline germination occurs over the normal life of the battery only happens a lot faster when the bombardment is overcharged or charged repeatedly without assuasive it to belch completely.

Severe crystalline formation can result in the larger and sharper edges of the crystals causing permanent damage to the prison cell inside, facilitating rapid discharges and irreversible malfunction of the battery.

"A battery that hasn't been reconditioned in over one month may begin to show effects of crystalline formation. After five months at that place volition exist a noticeable degradation in battery performance. After 6 months in that location might be permanent and irreversible damage inside your cordless drill bombardment."

• So its good to recondition your Nickel drill battery once in 30-45 days. Reconditioning requires the battery to be completely discharged to a voltage of 1V per cell. This kind of discharge is the most easily performed past following the deep discharge method described higher up for removing memory effect.
• Battery reconditioning devices are available in the market for reasonable prices. If you can find ane, a reconditioning charger is a good investment if you use cordless drills and other bombardment powered tools.
• Cheque your user transmission. The charger that came with your drill may already have the reconditioning role in information technology. Many modern tools come with the guideline that "its okay to leave the battery in the charger when not using it." This is because the charger takes the bombardment through the proper reconditioning and maintenance cycle when required.
• If none of these methods are possible perform the "deep discharge" like nosotros mentioned under reconditioning of retentiveness outcome. Circumspection: Do not perform manual deep discharges likewise often. Information technology also causes stress to a healthy battery.

Reconditioning A Li-ion Drill Battery

New, modern and expensive cordless drills might likewise come equipped with Lithium-ion batteries. These batteries are dissimilar from the same Nickel based batteries in every possible mode. The entire chemistry is dissimilar and and then is the behaviour. Li-ion batteries have no memory issue and hate deep discharges.

The best fashion to maintain your Li-ion batteries is to:

1. Charge it oft without letting it drop beneath 20-30% charge.
2. Operate it between thirty%-90% charge without either charging or discharging it fully. This will increment the charge cycles of the battery many times.
3. Operate and store information technology in a absurd surroundings as much every bit possible. Operation and chapters decreases in loftier temperatures.
4. Shop the battery in a partially charged land of twoscore-fifty%.
5. Recondition it by using the drill unremarkably till ability drops and requite it a full charge.

Li-ion batteries are smart batteries with a smart circuit built into them. Their chargers also usually know how to charge them properly.

Its not that important to charge the bombardment till only 80-90%. You tin charge it fully before use. Information technology is more of import to not discharge it completely. At that place are many ways of reconditioning a dead Li-ion battery. Here are some helpful resources.

Never buy another replacement battery.

Learn how to bring dorsum any battery back to life and and make it work like new again.

This is how y'all exercise it.
