Charging power tool batteries

I can't see that it would hurt anything. Computer maybe but not something simple like a charger. I have a 12 volt and run a off a cheap inverter.

Done it for years with no issues. Junkyard , Apr 8, Joined: Jan 4, Messages: Location: mn. I always have a 18 volt dewalt battery charging in my truck watt inverter hard wired under the seat a cheap one not pure sine had it that way for three years now and a coffee cup shaped inverter if i go in a different truck.

I've been using a watt Tripp Lite inverter for charging my Milwaukee 18 volt stuff in the field. Haven't had an issue. We have inverters in a lot of our service vans that have tool batteries plugged in.

No problems Our battery supplier has cautioned me to not use the cheap inverters. It will shorten the lifespan of the batteries and chargers. A lot of the cheap inverters don't make true sine waves and a lot of chargers can not deal with poor input waveforms. Camshawn , Apr 8, I have a buddy that does concrete work, and he used to charge his batteries with a generator.

He has a pretty high duty cycle, sometimes batteries get charged times per day. He did have issues with chargers, usually lose a couple a season.

Using another battery: For example, your 18V impact driver with a Makita 18V lithium-ion battery has stopped working. With the help of an AC adapter for example an old phone charger : You can fix a dead lithium-ion battery up in few minutes.

Cut the end of an old mobile phone charger that is not in use. Separate the two wires and remove their cable covers. They are going to play the role of booster cables. Never mix up the positive and negative ends. You can either put something over it or turn it face down. Then slowly uncover the panel. As more light hits the panel, its output voltage will go up. When the voltage reaches Then slowly cover the panel. When the voltage drops to 13V, you should hear another click from the relay turning off.

If everything is working properly, then you are done. Now you are ready to connect all the components together. First connect the output of the charge controller to the battery. Then connect the solar panel to the input of the charge controller. The relay may turn on and off a few times while the circuit is powering up. Now you have your own solar charger.

This will let you charge your batteries anywhere that has sunlight. This can be really useful for working with power tools at remote project sites. Question 8 months ago on Introduction.

If I then connect the SAE connector to the charger that my drill batteries came with, will the charger act as a charge controller for the battery? Hi, thanks for sharing! How would you change this to cope with changing conditions? I would like to use this as a mobile solution to charge a 18V power bank and ensure the device will always be pulling the maximum power available.

Want to build mine with a second set of resistors and a switch to charge at two different voltages. I'll add some caps too, it'll allow those to charge while the battery is in the tool. I don't want to be one screw short at dusk with no juice.

Thank you. Reply 4 years ago. Reply 5 years ago. I just ordered the parts to make one. Can you please let me know, while charging the batteries the cooling fans and a pump can run charging while the system is in use. I want to use it for lead acid batteries also will it harm the batteries? Reply 7 years ago. Different batteries need to be charged to different voltages and at different rates. I designed this charger for use with NiCd batteries.

So for safety, I am saying that it should be used with NiCd batteries. The charger would probably be fine to use with other types of batteries. I am just being extra cautious. Proceed at your own risk. Ive put led instead of relay and i set to reset at 10v and cutoff at Reply 7 years ago on Introduction.
