Need battery charger for a Cummins 18v cordless that I originally bought from Harbor Freight?

as harbor freight do not make batteries or chargers there is a possibility of identifying the manufacturer if you take the charger to a battery shop from the battery pack involved as well

Hello, Linda -

Clarification: You are seeking replacement batteries for a Chicago Electric Power Tools Cordless Circular Saw. If so . . .

Apparently new Chicago Electric Power Tools are exclusive to Harbor Freight.

I have not found specifications for your model circular saw, so I do not know what kind and what voltage a replacement battery or batteries would be. Instead, I suggest you make a telephone call to Harbor Freight Customer Service and ask about the availability of a replacement battery or replacement batteries for your cordless circular saw.

Note: Before calling Harbor Freight Customer Service, I suggest you investigate the cost of buying a new similar cordless circular saw. My experience with some cordless power tolls is that the replacement rechargeable battery was more expensive than buying a new cordless tool. (Meaning: The old cordless power tool was sent to electronics recycling, and not just tossed in the trash.)

This is the Customer Service telephone number for Harbor Freight:
800-444-3353
Monday - Saturday 5am to 8pm (Pacific Time)
Sunday 6am - 6pm (Pacific Time)

Best wishes.

The charger for the dewalt 18V battery.

It is a sealed unit and not worth trying. Go to ebay etc or a Black & Decker stockist for another battery

Harbor Freight sells universal chargers for DeWalts

I have to be the bearer of bad news. These are mass produced to give you the lowest price possible. They are made in Keorea/Taiwan and unfortunately do not make replacement parts. These are sold to any company that pays enough to put their name on it. Shop force makes the same drill and several other brands. So when something goes bad you have to replace the entire drill (only comes in the combo pk). You can't buy seperate pieces. Try shop force or Master craft. They're similar to what you have. Found one on Ebay. IF you keep looking you can probably find a seller with just the charger. Good luck

You will need he correct charger, the 24V will destry a very expensive battery.

I've open the charger and found that Q4 is open. But they have removed the part number from the component so you can't get a replacement.
