Cordless Drill Battery Question
Posted on 6/26/22 at 11:30 am
Posted on 6/26/22 at 11:30 am
My drill battery has finally died. The drill came with NiCad battery, but I am now seeing Lithium replacement batteries that will fit the drill. My question is, can I use the same charger with the lithium battery as I used with the original NiCad batteries?

Without any specific info I would recommend looking at the lithium battery and determining if that would fit on your charger. For example it's obvious just by looking at them that my DeWalt nicad and lithium batteries would not be able to share a charger

The old battery appears to be identical to the new one….it fits the same drill and the same charger. I know that lithium batteries typically require a considerably more elaborate charger than the NiCad

My guess is that you need a new charger, but I would have to research the specific brand and model to know for sure. Nicad and lithium batteries have different voltages (as well as different charge methods), so the charger would need to know the difference.

I think the answer is no.

It is important to know that the charger that came with the NiCad battery will NOT operate with the Lithium ion battery.

Probably cheaper to buy a new drill.

Some lines have chargers that work with the nicad and lithium batteries. They have the BMS built into the battery. Dewalt's 12v line has a charger designed for nicad and lithium.

i have a whole set of 18v DeWalt tools and the nicads bit the dust. the replacement OEM batteries were RIDICULOUS so i was looking at buying a whole new set of tools until i hit amazon and found a 2-pack of 18v LiON that fit the existing charger for like $35.
took a chance and holy crap
tools have never worked better. i forgot how good these things worked spending the last few years on dying batteries. the new batteries even have a charge indicator i didn't have on the old ones so i can quickly tell if the battery is good to go.
the only caveat: i pull them off the charger when they are fully charged. if not they tend to discharge over time but i can live with that minor inconvenience since they charge in like 15 minutes; even if both are dead its quick work to have them at 100%.
in short, try amazon. even if they don't work you just return them in 30 days for free so there's no risk.
don't throw out your tools due to some bullshite planned obsolescence. my 18v tools are strong and last forever with the new LION batteries. cant believe i almost spend $300+ on a whole new set of 20v tools.

I ordered the new batteries this evening!

I love the down votes I got for suggesting you might be able to keep using your old tools instead of throwing them away.

you got a link?

I'm driving right now but posted the link on the home board a couple weeks ago

Well, I received the replacement battery today and all I can say is WOW, what a difference! The lithium ion battery is literally a quarter of the weight of the old one, which made me suspicious. I plugged the new battery up and it charged in 20 minutes, just like Cadx suggested. I then took the drill outside and put several screws completely through some 2X4 lumber. I can honestly say the drill is better than new!

Does it use your old charger, or did it come with one? I suppose if the charger isn't designed to charge nicad and li-ion then the bms in the li-ion pack could be smart enough to charge itself with the old nicad charger.

I got one for my Dewalt 18v stuff and old charger charged it right up.

At the very least, throw the old charger out and get a new one. The Ni-cad charger will 'overcharge' and you're looking at a fire. That's just not worth the small amount of money a charger costs.
The other issue, which is sneakier, is battery depletion.
Lithium batteries don't like to run all the way down, there are circuits involved in the tool/battery that prevent this. Problem is, most of the time it's a combo of both tool and battery. So, if you aren't running what is "native" (same gen tool and battery, same brand), that is bypassed, and you CAN run the battery too low.
The standard charger will not recharge if you do, it flashes the "battery warning" at that point.
This can happen if you're running an adapter, say to run a Makita with a Dewalt battery, etc. Normal casual use won't do it, but if you're doing something a long time and really run the battery down, it's a big risk.
I've had this happen, had to take a battery apart and bump-charge it. If you google it, it's pretty easy to find. I've had to bump-charge a Ryobi battery back up to, I think, 13v, before the regular charger will charge it again.

i dont know about ryobi, but i've had these new dewalt 18v nicad replacement/LIONs for about 3 years now (built that deck project with the new batteries last year) and i haven't done anything special with the old dewalt charger except i dont leave the batteries on it for an extended period of time.
i have definitely run these down all the way and literally 30 minutes on the charger gets enough juice to chew through a lot of 2x4s.
i learned my lesson leaving the battery on the charger for several weeks. battery was dead when i pulled it off but slapping it back into the charger & coming back an hour later and it was charged.
YMMV but these have more than paid for themselves bringing my 2010 18v tools back to life.
