I have one of those cordless drills that has a 24 volt
battery. I was wondering what would happen if I unplugged the
charger from the wall, and left the battery in it. Will the
charger discharge the battery if I dont pull it out of the
charger?

Also, someone gave me an 18 volt drill that has the identical
looking battery, except the battery is an 18 volt, not a 24.
That drill did work when he gave it to me, but his charger
died, and he just bought a new drill. Can I plug that 18V
battery in the 24V charger or will I damage the battery? It
does fit into the hole on the charger. I dont think 6 volts
is that much different, but it may be for the battery.

GMU

Here's a thought: Call the manufacturer and give them the model
number of the charger and batteries. I'll bet they know the
answer to both questions.

they might even have the manuals online. RTFM.

What a bunch of crap.

Do you really think that if I call DeWalt Customer Service and ask
them which batteries their model DW9116 charger will safely handle
they're going to try to sell me something? At a minimum they are
going to transfer me to tech support or an on-line manual. At best
they will get the information themselves and give it to me.

Here, try it: 1-800-4-DEWALT

Let us know what they try to sell you.

IMO,one should check for an online service support site BEFORE phoning
them. It aint that hard these days.Heck,you're already online making
these posts.Instead,some would rather have others do their research
for them.

Also,READ any manual you have at home,first.

No manual.
I bought this thing (USED) at an auction.
It's some off brand (no-name) drill. But for $20 I cant complain,
especially with 3 good 24v batteries, 2 identical drills, plus a
charger.

Then I got that 18volt drill that uses the same shaped battery (also
an off brand).

I'd think that ALL drill batteries should or should not be left in a
charger, which is why I am asking. What is the recommendations?
Can the battery voltage drain from being in an unplugged charger?
I like leaving it in the charger so I know which battery was recently
charged. Otherwise it's a guess...... (the drained ones are set near
the charger). Otherwise it comes down to putting masking tape on the
battery and labelling it by charge date.

chances are,any no-name drill is going to come with a simple charger;no
"smarts",charge times longer than 1 hour(3-5 hrs or more),and will probably
discharge the battery once the line power is turned off,and will overcharge
the pack if left on past the time needed to fully recharge the pack.

examine the charger and see what the charge times are.
open it up if you can and see what IC is controlling the charge.
Then look up the application note for that IC.(Google)
