Cordless circular saw

Recommended Posts

Hey, All! Haven't posted often here but I always love the advice of fellow woodworkers and tradesmen. I have a cordless circular saw which I bought years ago. It's a Craftsman 14.4 volt NiCd. Needless to say, the batteries are shot now and I'd like to upgrade. They don't make a 14.4 volt Li-ion battery for Craftsman (do they?) and I wondered if I could buy an 18 volt and remove cells. Then, how to charge?! Any advice would be appreciated.

There is a battery depot or something like that in my city that will swap cells in battery packs. I am not sure if the same charging unit will work with lithium cells but it can't hurt to ask at a place like that.

Cordless circ saws are pretty inexpensive these days.  Might be worth going to hd and buying a new model.  I bought the ridgid combo kit with the cordless circ saw, drill, some batts, charger, and a bag for like 149 or something similar.

It Li-ion and lifetime warranty

Thanks for the replies, folks. I've been using an 18v battery and no ill effects so far. But I won't push it. I'll pull the trigger on a new Ridgid combo soon, I think.

Did you have to modify the battery?

I just bought a Dewalt 20V circ saw from HD a couple weeks ago. I went with this saw because it uses the same battery that my dewalt miter saw uses. I also bought a couple extra batteries. I upgraded the blade and have no issues with the saw. I have not used it a lot but it seems decent, however I am not using it for any furniture builds but did come in handy when I needed to break down some plywood to build a shooting board. It's nice and compact and there are no cords in the way. It is a little weak on power so I would not go crazy using it with any 6/4 or 8/4 hardwoods. If I were build a shed or deck out in a backyard this circ saw would be my best friend.

It would probably be best to bury a new saw. 14.4v is the equivalent to 12 nicad batteries in series. Lithium ion batteries can not be charged by a nicad charger as it is a different way of charging, and the cells need to be balanced as they are charged.

I agree with you guys, especially about just getting a new saw. I really like my old one-it's sooooo lightweight! And I just strapped in a Ryobi lithium battery. Used a Velcro strap and it stayed in. I removed the battery afterwards. I may just get the Ryobi saw, not the Ridgid, as I posted earlier.

Add my vote to the 20 volt lithium DeWalt camp.

It's a good little saw with a lot of power and a long battery life. Plus one huge perk of the Li Ion battery is that it runs full power until the battery dies, then it just stops - it doesn't seem to gradually weaken like older styles of batteries do.
