Battery drill external battery pack
Stormin Mormon
cordless drill, and external battery pack? For a
while, I was saving a 12 volt drill that was dead.
I save it, becuase I figured I could put a length of
zipcord on it, and run it to a lighter plug. Power it
from the socket of a battery jumper pack.
Most Sub-C that I've found in drills are 1600 mA
hours, Compared to the cheap Rayovac NiMH AA
cells, which are about 2,000. could use a 12 volt
pack that runs AA cells (eight AA cells, Rat Shack
used to have these) and actually have more power
than the original pack. Plus, being able to test and
replace individual cells as they failed.

No, but I have, on a couple of occasions, cracked open the original
battery and replaced the cells inside.

That must have been at least 20 years ago. I just bought some 4200mAh
NiMH ones. That is suspiciously high, though. Around 3000mAh is more
common.

There's no point. Once the first cell dies, the rest are not far
behind. Also, an automatic charger could get confused if the battery
had a mix of fresh and old cells. In the long run, it's much better
economy to replace all cells at the same time.

I looked at doing that once. The original cells were spot-welded
together with tabs of SS. How do you connect 8 individual Li-Ion cells?

9.6 and even 7.2 volt drills will run a LONG time on 12 volt battery.
A friend build a Zenith 701 using a 7.2 Makita on a 12 volt battery -
and that's a LOT of holes.

from it. I tore apart a dead battery pack for my 12 volt Dewalt drill
about a year ago, with that very plan in mind. I used to use that drill
to tap maple trees and I could get about 50 taps per charge. That's
drilling a 7/16" hole about 2 inches deep.
The idea is to simply strap a garden tractor battery to my back as I
tap the trees. I shouldn't have to go back to the trail to get a fresh
battery all day.
I would use something more substantial than zip cord, though. IIRC 16
wire isn't good for much over 4 amps. Why waste ANY power?--- I'd use
12 Ga extension cord wire.

Question of where you want to spend your effort on that use - I tapped
about 200 trees using a brace and bit - the old fashioned cordless
drill. I've also driven a lot of screws with them, including quite a
number when all the new-fangled drills in the area were waiting on the
charger. I'd much rather tromp around carrying & powering the brace and
bit than carry a heavy battery (or one of those gawd-awful gasoline
drills some folks just love.)
I also have a 12V drill awaiting the car-battery conversion - just don't
see using it for that job, considering.

As to AC power, I know 14 gage is rated 15 amps, so 16
should be 10 amps or so rated. DC? I really don't know.
Vehicle starting batteries don't like deep discharges. If
you do 25 holes between recharges. Your battery will last a
lot longer.

Yes I have. I had an older sears drill, and one of the battery packs
died. After the autopsy, I soldered heavy zipcord to the contacts.
A cigarette plug on the other end went into a AGM battery, 12v 6Ah.
Draws a lot of power, about 20A.

You might find that the AA cell packs won't handle that much current.

Yep, would work - but why? - you've bypassed the fundamental design
objective of a "Cordless" drill. If you have to put up with cables all
over the place, use a mains powered one. But I must admit, theres one
glaring exception - using a modded one to raise and lower the
stabilisers on your caravan/rv. Beats winding 4 of them by hand, cheap
enuff so theres no major drama if it breaks/goes walkies.
NiCads - here at any rate, they are too expensive to replace a pack
with brand name cells. Too much, considering the cost of a new drill,
usually with 2 batteries nowadays. (And salvage rights on the old ones
- )
And in a reply to your query re my post, I dont want the chuck, I
wanted the motor and the control electronics to build a power feed for
my mini-mill. Combining 2 net references - one guy used the cordless
drill motor and slightly modified the speed controls, another person
came up with a nifty coupling that could be easily engaged/disengaged.
Got the housing built, and the motor mounts as well, need to machine
the drive coupling to the mill lead screw. No precision, just power
feed and rapid traverse, so any slop isn't a problem....
Andrew VK3BFA
Wild_Bill
power feeds, but I haven't noticed a coupler that's easy to dis/engage.

Thats pretty much how I was figuring it as well.
After reading this thread..Ill be converting a very nice high end
Craftsman cordless drill to external battery pack. I picked it up at a
yard sale for $2. All three battery packs are stone dead and wont take a
charge.
Ill gut one pack, hook a long wire to it and connect to a battery. The
other two battery packs Ill save and perhaps rebuild when money gets
better.

Yep. Current varies with load. 20A was the highest I got it with a
quick test. Might be more with a bigger load or different drill.
I think you could do some light drilling with a 10A limit.

You can open them up and add heaver wire and a bigger breaker, or make
up a lighter socket that you can attach to the jumper clamps.

It's usually quicker to use than a corded 110V, and the cables are much
longer, and it has an adjustable clutch which I use a lot.

Your a professional Gunner - it is expected you have a working
cordless drill. And if your going to drill more than a few little
holes, then you have to use a powered drill anyway.
Your power cables should be on reels for easy deployment/recovery
anyway, so its no great drama to run them out. In the back of your
truck, near the back door for easy access. I found that the plastic
spools that MIG wire comes on are great, fairly bit internal diameter
so don't crimp or stress the cable.

Why? Granted..I do have both professional grade cordless and wired
drills in my truck, some applications pretty much beg for long lasting
cordless drills. For example, putting together a steel shed kit.
I did that a year ago last November, prior to my medical issues. Took
me 12 hours of labor to assemble it. The shed was 150 feet from the
nearest power source so I used one of my 18vlt cordless drills. It
should have taken me 10hrs or less simply because I was running out of
battery regularly. There was no power on the site, I should mention as
well.
Doing further work, I had to bring one of my several gennies out there
and it was a pain in the ass to listen to it running 8 hrs a day. Not
to mention..the fuel and wear costs.
