It depends on the wattage of the drill battery charger. The higher the wattage, the faster the battery will charge. Generally speaking, it can take around 45 minutes to several hours to charge 18V drill battery depending on the wattage.
Most battery chargers are about 15-20 watts so it can take about 1-2 hours to fully charge a 18V drill battery.
How long does a 18V 1.5 Ah battery take to charge?
The charge time for a 18V 1.5 Ah battery can vary depending on the charger and how depleted the battery is. Generally, it will take around 3 to 4 hours to charge a fully depleted 18V 1.5 Ah battery if it is being charged with a standard 18V charger with an amplification rate of 1.5A.
If a higher rated charger is used, such as one with an amplification rate of 3A, then it can take as little as 1.5 hours to charge a fully depleted 18V 1.5 Ah battery. The charge time will also be affected by how often the battery is used, so if the battery is regularly re-charged after every use then the charge time will be much lower.
Can you overcharge a Makita battery?
No, you cannot overcharge a Makita battery. Makita batteries are equipped with an automatic cut-off system that prevents overcharging. The battery will automatically stop receiving a charge when it is full and will not accept any additional charge.
It is a built-in safety system that ensures your battery gets the needed charge without damaging the cells inside. Additionally, Makita batteries are designed to be left in the charger and not to be plugged in all the time, so you do not need to worry about overcharging the battery.
Is it OK to leave a lithium ion battery on the charger?
Yes, it is generally OK to leave a lithium ion battery on the charger for an extended period of time. Lithium ion batteries use a system called “charging cutoff” that prevents the battery from overcharging, which can cause damage.
Most chargers will automatically recognize when the battery is fully charged and cut off the current. This means that you can safely leave the battery on the charger without fear of it becoming damaged from overcharging.
It is important to note, however, that leaving batteries on the charger constantly can lead to a decrease in overall battery life. To maximize the life of your battery, it is best to remove it from the charger as soon as it is fully charged.

How do you bring a dead drill battery back to life?
Reviving a dead drill battery is possible but will require time and patience. The most important thing is to identify why the battery is dead in the first place – likely the cause is either it is not receiving enough charge, or a short in the battery itself.
If the battery is simply not getting enough charge, then you’ll need to plug it into a charger for a few hours and see if it will begin to charge up. You can use either a smart charger, which will adjust its charger rate depending on the condition of the battery, or a standard charger, which will charge in a fixed manner.
While the smart charger is recommended, the standard charger should still be able to give the battery a much-needed jolt.
If the battery is showing signs of a short, then you may need to do some more troubleshooting. Disconnect the battery from the charger and test it with a multimeter – if it is shorted out, then you’ll need to replace the battery.
But before you do that, try to figure out what caused the short in the first place by doing a physical inspection of the battery to check for signs of corrosion, loose wires, etc. If the issue persists, then you’ll need to replace it.
In either case, it’s best to practice caution – always be sure to use a charger that is compatible with your battery, and never try to charge a damaged battery. If you feel uncertain about the situation, it’s always best to consult an experienced professional to ensure that you don’t cause any further damage.
How do you jump a drill battery?
To jump a drill battery, you’ll first need to make sure you have the right tools and safety equipment. You’ll need two jumper cables long enough to reach both the dead and live batteries, a wrench, and safety goggles and gloves.
Once you have all the necessary supplies, position the vehicles close together so the jumper cables can reach both batteries. Shut off the ignition of both vehicles and pop the hoods. Connect one end of the red (positive) cable to the live battery and the other end of the red cable to the dead battery.
Connect the black (negative) cable to the live battery, then to an unpainted metal surface on the other vehicle. Start the vehicle with the live battery and let it run for a few minutes, then attempt to start the vehicle with the dead battery.
If the dead battery does not start, let it rest for at least 10 minutes before attempting to jump it again. When you are ready to disconnect the cables, do so in the reverse order. Be sure to dispose of the dead battery responsibly and replace it with a new one.
How do you charge a dead power tool battery?
Charging a dead power tool battery requires that you first determine what type of battery your power tool uses. Some of the more common batteries are: NiMH, NiCd, and Li-ion. Once you identify the type of battery, you will need to locate the appropriate charger for your battery.
Once the battery and charger have been determined, you can begin charging.
Charging NiMH or NiCd batteries is relatively simple. Start by connecting the red charger cable to the positive port of your NiMH or NiCd battery. Then connect the black charger cable to the negative port.
Plug the charger into a power source, and turn it on. Most NiMH and NiCd chargers have a built-in timer that will shut off when the battery is fully charged. Li-ion batteries require a different type of charger and must be charged with caution.
To charge a Li-ion battery, connect the red charger cable to the positive port of your Li-ion battery. Then connect the black charger cable to the negative port. Plug the charger into a power source, and then press and hold the charge button.
Continue to hold the charge button until the battery is completely charged, and then release the button.
Before you begin charging a power tool battery, it is important to read the instructions in the user manual. This will provide the safest and most efficient charging instructions to ensure that your battery is properly charged.

How can you tell a DeWalt battery fully charged?
When a DeWalt battery is fully charged, it will reach a full “state of charge”, which is indicated by both its LED lights as well as its voltage.
To tell if a DeWalt battery is charged, first look at the LED lights. The LED lights can indicate whether a battery is fully charged, charging, or in need of charging. Most DeWalt battery packs have three LED lights.
The left light indicates the charge level, with a green light indicating the battery is charged up to 75%, a yellow light indicating it is 75–100%, and a red light indicating it is time to charge the battery.
The middle light indicates if the battery is in the charging process, and the right light indicates if the battery is too hot or cold for charging.
In addition to the LED lights, you can also check the battery voltage using a voltmeter. For most DeWalt batteries, the voltage should between 40–60 volts when fully charged. If the voltage is lower than 40, the battery needs charging; higher than 60 volts and it is likely in a condition of overcharge and needs to be shut off or disconnected from the charger to be protected from damage.
