Battery reviving is the process of restoring a battery to its optimal condition and performance after it has become discharged or weakened over time. A dead drill battery is considered as zero voltage and capacity battery which has lost its power and voltage completely. You can identify a dead drill battery by using these signs such as zero multimeter reading, impossible to power up tools, battery is not charging, battery switch is not working, corroded terminals and battery.
A dead drill battery can revived using a fully charged drill battery and conduction cable by connecting similar terminals together. After connecting similar terminal you have to keep them about 5 -10 minutes. After that you can use a regular charger to charge the drill battery as usual.
Drill battery reviving has both pros and cons. It can save time, you can have self-satisfaction from it and it is an environmentally friendly task. As cons of drill battery reviving are it is cautious of exploding, unable to provide the exact voltage for reviving and needs better electrical knowledge for better results. You can use this method to jumpstart a car battery successfully.
What is Battery Reviving?
Battery reviving is the process of restoring a battery to its optimal condition and performance after it has become discharged or weakened over time. This can be done through various techniques such as recharging, desulfation, equalization, or replacing damaged cells or components. The goal of the battery reviving is to improve the battery’s capacity (Ah), efficiency, and lifespan so that it can function effectively and reliably.
What is a Dead Drill Battery?
A dead drill battery is a power drill battery that has completely lost its charge. Theoretically its capacity and voltage is zero (AH=0, V=0). Hence it is unable to power up the tool. This can happen when the battery is discharged over time or if it is not used for an extended period. A dead drill battery will no longer hold a charge and needs to be revived or replaced in order for the drill to function properly.
How to Identify a Dead Drill Battery?
We can identify the drill battery whether it is dead or is there any problem by following the below signs.
- Dead Drill Battery Shows Zero on Multimeter – You can see zero voltage and current if the drill battery is dead. You can check voltage by connection B+ and B- terminals in the drill battery. Multimeter should be connected parallel to the battery to measure the voltage while you need another load to check the capacity of the drill battery.
- Dead Drill Battery Does not Powerup the Tool – When you try to use a dead drill battery in the tool, you can observe it is completely not working.
- Dead Drill Battery is Not Charging – When you keep the battery on the charger, you can observe drill battery is not charging. Because dead drill batteries are not able to hold the charge.
- Dead Drill Battery Switch is Not Working – When you press the battery switch, you can see it is not on status. It is always off. So check two or three times if the battery is on/off using the switch. Regularly when you are on the battery, you can observe the battery level by indicating the lights.
- Dead Drill Battery Has a Rusting Terminals – If your battery is heavily open to the water, terminals can be rusting. These rusting layers will disconnect the charger and tool. So it can use for the tool or charger.
- Dead Drill Battery Can be Rusting – When a battery is open to air a long period, its inside can be rusting. Because of this, the battery can be dead. When there is rusting, the inside can be short, and the battery will discharge rapidly.
If these things can be seen in your battery, you should make sure it has died.
How to Revive a Dead Drill Battery?
You can revive a dead drill battery by following the below step by step guide. You will need fully charged same voltage drill battery and conduction wires to jump start the dead drill battery.
- Clean any rusting inside or terminals.
- Have the same type of fully charged drill battery
- Find the terminals (B+,B-). If there is no sign, do not try and test. Use a multimeter to find the terminals.
- Connect both (B+,B+, and B-,B-) using a conduction wire. You can use scissors, wire, pin, or any condition medium.
- Keep both for about 5-10 mins.
- Then try to charge using the recommended charger
- If this is unsuccessful, check the inside of the drill battery and clean it.
- Check the voltage of inside cells and then replace the dead cells.
What are the Pros and Cons of Drill Battery Reviving?
There are both pros and cons to any task. If we use the reviving jumpstart method, there are also pros and cons.
Pros of Drill Battery reviving
- Save time and money
- Self-satisfaction
- Reuse equipments
- Environmental friendly
Cons of Drill battery reviving
- Caution of exploding
- Lack of providing the proper voltage and current for reviving
- Better reviving needs extra electrician knowledge.
How to Avoid a Drill Battery Fully Discharging?
You can avoid a drill battery fully discharging by following the below methods.
- Do not use a drill battery in an environment that is more than 50 °C.
- Do not use with extra loaded tools or equipment
- Use proper tool mechanisms for the material every time.
- Store in a proper place
- Do not keep with a tool for more than 12 hours if you don’t use it.
- Avoid high humidity and open areas to sunlight.
- Charge 10% – 90% and avoid 0% – 100%
Can I Jumpstart Car Battery Using a Drill Battery?
Normally a dead car battery can jumpstart by using a fully charged drill battery. You will need an 18V or more voltage drill battery to jumpstart the car battery. You have to connect similar terminals using the conduction wire and keep them for about 10-15 mins and then try to switch on the car.
