Charging a Cordless Drill on 12V?

I know I am late to the conversation .
RickW do you have any idea how many amps the drill draws when on 12V
Can you use the camper batt? I also have the Ryobi and it seems the ni cads are on their way out.
I will conver one of my batts like you did before I throw a good drill away or have to buy a lithium bat and charger.My alt on the truck will provide up to 14.5 volts,
is it better to run off the truck.
Thanks

Hi RWD

I do not know the amp draw-I don't have a DC clamp-on ammeter. I use the cigarette lighter plug that normally uses a 10 amp fuse (I think). If you need more amps, use heavier wire and the battery clamps like uncle bud above.

I can use the 12 volt circuit in the truck, camper or with a portable 12 volt battery. I can raise all 4 jacks with one small drill battery, which I believe has a capacity of 5 Ah.

I have a number of Ryobi tools that all use the same battery so it is cost effective for me to have the Li-ion batteries and chargers. They perform much better than the old nicads.

You can sometimes get a good deal on new Ryobi batteries around thanksgiving or after Christmas.

Hope this helps,

Rick thanks for reply I believe all the lighter plugs are 15 amp,so I should be good to go

My hardwired 9.6v craftsman drill can blow a 35 amp ATC fuse if braked to a stop, but not a 40 amp one.

I'd not trust a ciggy plug to pass 10 amps for any duration.

My first hardwiring of a cordless drill, I used a 18 awg ciggy plug cord as it was all I had available, and the torque available was an absolute joke. And I had to wrap the ciggy plug fuse in aluminum foil the first time I used it.

If you've got a dying cordless battery, find a Batteries Plus store or similar - they will rebuild the pack for about half of what a new one costs. I've got a rebuilt pack & an OEM pack for my drill & the OEM one has pretty much given up while the rebuilt just keeps going & going. Gonna have the weak one rebuilt sometime soon.

There are way too many different tool batteries. I wonder how we managed to get AA, AAA, C and D battery standards. I guess a standard tool battery would cut into company profits, though.

Ironically... If you open up a tool battery, you'll find that most of them are stuffed with what appear to be standard AA, C or D NiCD or NiMH rechargeable batteries. They're soldered together in series to produce the desired output voltage (each one contributes 1.2v).

I'm glad it worked for you
My experience was different, but I was not running up jacks
I was drilling holes, and converting 18v to 12v
Did not provide the needed torque the drill would stall
Each situation is different, I was thinking of full load torque
Not of the jacks, which was the topic of discussion...My mistake
