How To Charge A Drill Battery Without Charger

The cordless drill cannot be used with non-waterproof batteries. Each manufacturer provides a dedicated battery charger that comes with the drill. In the worst case, the battery charger can die for various reasons. In this blog post, we will discuss how to charge the drill battery wirelessly without a charger.You can charge it without a charger with a car battery if it is rated at 12V. Using a variable DC voltage source is also a very reliable way to charge any type of rechargeable battery. You can also use a laptop charger for 18V or 20V drill batteries, or attached AA cells, or other drill batteries, or a balanced lipo charger. You can also use the 12V solar panel to charge the battery without a charger. The science behind wireless charging is like charging a Li-ion battery with a charger. The science behind charging Li-ion batteries is the same as charging any rechargeable battery (this is important).

How to charge any battery without charger?

The answer is simple, provide the battery’s rated voltage at both terminals. As shown in the first image of topqa.info, the voltage supplied is zero, so no charging is required. When the voltage rises to 12V, it will start charging. In fact, it is not that simple. Charging starts as soon as the potential difference increases, which means if the 12V battery is discharged and drops to 6V, as soon as you connect it to a voltage source above 6 it will start charging. The charging speed is also proportional to the voltage difference. Fast charging. More than rated voltage is applied at the beginning of the charge cycle and drops to rated voltage when the battery is about to fully charge. This is another very cheap alternative product but the quality is not outstanding.Caution: Fast charging requires proper BMS (Battery Management System) to avoid any malfunction or fire. All batteries are not designed for fast charging.

Charge Li-ion battery without charger

Okay, now that we’ve discussed how to charge any type of battery, let’s move on to Li-Ion batteries. A single lithium-ion cell is rated at 3.7 V, the cut-off voltage at charge is 4.2 V and the cut-off voltage at discharge is 3.0 Volt. This means that, at the end of the charge cycle, the cell’s voltage should not be greater than 4.2 V, and at the end of the discharge cycle, the cell’s voltage should not be less than 3.0 V. As most of the cordless drills are powered by Li-ion batteries, how come they have 12-18V batteries? The answer is simple; they consist of many li-ion cells stacked in parallel and in series, as shown in the image. The parallel cells only affect the amp-hours of the battery.

Standard unbalanced charge

Many of these pins are connected to each cell’s stack to balance its charge. As shown in the image above, each cell is individually accessible for charging. Learn more about the battery inside at this link. In a standard charge, all we have to do is set the rated voltage at both ends and wait for the battery to charge. To avoid any damage to the battery, it is recommended to charge at 12V instead of 12.6V as shown in the image above.

Balance fee

Balanced charging takes more than standard unbalanced charging. You will need a special balanced charger used by RC pack enthusiasts. They are cheap but have a big overhead with a lot of parameter control.During standard charging, we only apply a nominal voltage of 12v (12.6 in case of Li-Ion) at both terminals to charge the battery. During balanced charging, a dedicated Li-Ion power bank can be used to balance the voltage of each cell at 4.2 Volt to maximize battery life and health.The charger provided by the drill manufacturer takes care of charging each cell and balances its voltage at the same 4.1-4.2V when fully charged. This won’t happen when you’re planning to charge the battery yourself, but it’s still a good idea to understand the process better. You will have to charge the battery as follows if you want balanced charging. There are many options for balance charges on Amazon, but SKYRC B6 is my favorite as it comes with lots of connectors and cables to help you charge any battery you have. I mean any rechargeable battery.

Tips: How to charge the cordless drill battery without a charger

Now, let’s move on to the most interesting part. How to charge a battery without a charger at home Usually we don’t have a variable voltage source. These voltage sources are expensive and hard to find. So we need to find a hack to charge our dead battery Assumption: I’m assuming you will probably charge an old battery that came with your outdated drill and you don’t want to start charging. Invest in a new charger or the charger is no longer available For newer batteries, we recommend purchasing an appropriate charger to extend battery life. topqa.info, let’s get to the point. As discussed earlier, all you need is the same amount of voltage as topqa. Here are a few ways you can get that desired voltage:

• Your car battery – The perfect 12V voltage source
• Laptop Charger – 12V to 18-19V . Voltage Source
• Simple AA Cell – Can produce any amount of voltage
• Cheap voltage regulator/converter
• Other drill battery
• Solar panel

Charge the cordless drill with car battery

WORK AT YOUR OWN RISK: Risks involved – Shortening the terminals of car batteries, overcharging batteries with voltage as low as 12V and exploding.Car batteries are one of the best ways to charge your 12V cordless drill. You don’t need to worry about charging your car battery as it will be automatically charged by the car alternator as you drive. In case your car battery is dying and you need to replace it, this is the option that I always choose. They come with a 36-month warranty, all you need to do is connect the drill battery terminal to the car battery terminal. As said earlier, connect positive to positive and negative to negative Read more: How long does primer take to dry If you have the same car battery that is being used for other things like UPS etc. At home, you can also use it. Make sure that the battery you are about to charge has a rated voltage of 12V and that your car battery is also rated for 12V.Charge a 12V battery with a car battery. Also known as Jump Start.

Charge the drill cord wirelessly with a laptop charger

Most laptop chargers are rated for 18-20V, which is great for charging 18V batteries. This process is very simple. Understand the type of connector your laptop charger has. Then keep a compatible female connector (Get these). Solder the female connector to the battery internal connections (Anode to anode and cathode to cathode). Make a hole to plug the female connector in and voila, you can charge the battery without an official charger. connector like this and make a connection in a positive and negative way with topqa.info Apple Macbook charger (old Megsafe) rated at 14/16/18/20V. You can easily charge an 18V battery with an 18-20 volt charger. Check output voltage rating. Still, the process is very simple, connecting positive with positive and negative with negative. One problem with the Megsafe charger is that getting the connections from its pins is tricky and keeping the female pins in place is hard, so you’ll have to do this. Note that the center wire will be positive, and the outer grid will be negative. Caution: This will damage your MagSafe charger beyond repair.

Charge the battery when 1.5V . AA Cells are available

This is an expensive and inefficient way, but it can save lives. In extreme cases, when you can’t find any voltage source, you can get simple pre-existing 1.5V AA Cells and connect them in series to produce the desired voltage. 9 cells in series with a total of 13.5 V to charge a 12V battery and 13 cells in series with a total of 19.5V to charge an 18V battery. They may not fully charge your battery as these with topqa.info at minimum may also contain rechargeable AA cells and they mostly come with a charger, but that would be expensive. However, worth sharing.

Charge the battery with a cheap voltage adapter

The process is the same as in a laptop charger, but this is an inexpensive voltage regulator available at electronics stores and online. Buy these 12V and 18V converters from Amazon and they should work fine. I find this to be quite convincing. It’s cheap and comes with plenty of ports to connect to the battery. Do a thorough search.

Charge the battery with another drill battery

This is also a great hack. If you have another drill battery with a working charger, you can use that drill battery to charge it. Make sure that the remaining battery has the same voltage and is fully charged. Now connect the terminals in the same pole. Positive with positive and negative with negative. You will have to use jumper wires for the connections. It won’t be a definite solution but might work in topqa.info also can buy universal drill batteries from Amazon. Check out the options here.

Charge battery by solar panel

Solar panels are an excellent source of DC Voltage. However, there is a problem. The output voltage is not fixed and changes due to the change of sun direction and temperature. A 12V rated solar panel has an output voltage of 17 volts, which is regulated down to 13-15 volts to charge a 12V battery. Just make sure the panel is designed for a 12V battery system and then you can connect directly to the battery without the MTTB controller. Make sure your battery doesn’t become too hot to avoid any problems. I would personally recommend this 12V panel. Other than that, these are all hacks and will be done with more care.
