It would probably still work but the light would not be as bright due to the lower voltage. I don't believe anything "bad" would happen. The light was designed to run on a higher voltage of the rechargeable battery. Now if it was the other way around and it was designed to run on the lower...
I would assume you bought a new battery pack because the older one was not at a very good level of holding capacity any more. I think it should show very quickly which is which. But I really don't know your whole story about your batteries.
Not in the far off future but in the next 5~10 years, the biggest thing is going to be how your flashlight is powered. Yes battery technology is going to make the biggest difference in the near future. No moore's law with batteries but it's chuggin along. LED tech will improve also and be more...
Just a quick update on the power tool battery pack. The jump start method did the trick, I took a good pack and a couple jumper wires pos to pos / neg to neg 10 minutes later it would take a charge on the Porter Cable charger.

Yes it looks like security T bits to take it apart. They get ya pretty good $$ on OEM battery packs. It hasn't been used all that much, I hope I didn't put it away too low state of charge.
I've read threads of doing this with "single" cells but I didn't think about doing this with the battery pack. Thanks I'll give this a go.
PS. Should I tell my attorney coffeecup66 said it's ok? :twothumbs just kiddin.
Well I guess I could remove the cells and try to charge each one separately . It might bring them back up to where the charger would charge them again.
It will not take any charge at all, It's 1 of the 2 that came with the drill, If I do take it apart I can check each cell for there condition. If I go ahead and replace the cell it would be all the cells for obvious reasons .
Obviously in my post I "did" think they have a BMS inside them, but was not sure if there was something more to it.
So it seems it would be a simple swapping of a few cells and soldering. I've not had the need to do this before.
It's a 20V.
I've got a Porter Cable drill battery that's dead, my question is do they usually have a BMS inside them?
Kinda thinking of taking it apart and replace the li-ion cells inside it. How else would the cells charge evenly on the charger?
Fully agree with Lynx Arc. There are some good choices for AA nimh batteries and run them in parallel x3. I have some in use with some lights I have. For the record, I don't have any first hand experience with the ELB batteries you're asking about. The 3 cell battery adapters I have only cost...
I'm using a FireFly drop-in with a 3D mag, nice upgrade for sure @ 800 lumen . I do wish the "on time memory" was a much shorter time however. The Magcharger FirerFly looks to be identical. The light took about a ten foot fall out a window and on to the driveway and still works just fine.
It does happen! It happened to me with 2x cr123 primary batteries in series in a flashlight (not in my mouth thank God) while i was holding it in my hand with the light turned on and I was outside with no body behind the light where most of the energy blew out of the light. You could see there...
