Cordless drill battery repair or replacement?

Need a new battery too- a friend of mine says there's no difference in the motors and these will run with the 18v battery giving better torque

I would guess with my drill being a HP146F2B I could use the 18v HP188F2B battery...

And how do you plan on charging it? or for that matter even fitting it into the drill as it is clearly a different case sizing.

Apparently the only difference (two different pics from two different suppliers) is in the battery cells, but I didn't think about the charging aspect. Damn

Perhaps I should stick to the original plan of replacing the drill full stop, especially since after reading this thread I'm a little wiser as to battery choice... I obviously use mine too infrequently

I've got the same tools as this guy and have 3 dead batteries.
I will try it and post the results.

Oh! This thread keeps on giving. Got a new word now "glom". Gonna try & use it in a sentence tomorrow. Cheers.
Any hoo. Status update.
One of the postee's (that's a free word to ewes all) mentioned a kitchen fitting co using two drills. Hello, I thought, I spend more time fiddling with me chuck than I do drilling, as it were. If I can get the same drill, new batteries & all etc then I'm going to save a lot of time. A bit each way. Heh.
So I pop in to see if the Chancellor wanted a bucketful of pies for lunch & shared the idea feeling a bit smug. Pop went the smug bubble & out patoomed the "T'is a bad idea" she said around her Chicken Tikka in puff pastry (a whole chicken), I was crest fallen, "I've just ordered you a new Bosch. It will be here next week & can drill down coz it has an interchangeable thingy which lets you drill in tight spaces". My equipment is generally too big for tight spaces and I end up having to twiddle it with me fingers.
Roll on next week. And the inevitable "Can you just....." Happy days.

Thought I would start another battery thread as it is raining..

I have a Makita drill which has 14.4v, 1.3Ah Ni-Cd battery impersonators. They will hold enough charge to put a self tapper about 3mm through toilet paper (double ply, wet, with little dolphins on it). Not ideal. I priced up replacements, $80 each. I can buy the same drhttp://jaycar.co.nz/productView.asp?ID=SB2468&w=ni%2Dcd&form=KEYWORDill new with batteries etc for less than 2 batteries.
Can the existing batteries be nurtured back to life or am I buying a new drill?
Seems a bloody shame to bin a good bit of kit for the sake of batteries.

Opinions & options?

environmentally, get new batteries.

OR repack them yourself:

OR put a cord and some aligator clips on it and keep it in the car/boat.as a corded drill.

OR, ni-cd os old tech, and heavy, a new drill should be litium ion. - much lighter. and sexy.

You can often make one good battery pack from two duff ones.

They open up, and are essentially a bunch of 1.5V cells soldered together. Identify the dud cells by charging it before pulling it apart, and running the drill for a short burst. The dead ones will have no charge nearly straight away.

Get with the consumer program and buy a new one.
( says he with a mint Makita with dead battery sitting on shelf but too old skool to throw it away)

this.
except that they are nominally 1.2v cells.

Desperately want a Dewalt for the street cred it brings

You realise they are only a Black and Decker in drag!

Once Ni-Cad batteries don't hold a charge any more you can often extend their life by freezing them overnight (in a plastic bag, just in case) before thawing in the sun & re-charging. An old wives tale from way back but it works.

Whats the thoughts on that vid with the guy sparking his battery off a charger? If it works on Ni-Cads that's one thing but if it blows up the charger, shed or me, totally another.
Re Dewalt. I got my Sabre saw for $60, pre loved. Looks like it's an ex hire tool or has built half of Auckland. Not pretty.
I've thrashed it since it came home, got a growing collection of shagged blades. I cut up 9 tires today, each into 3. First few I used the saw to cut them up completely but the damage the bead core does to a blade finally made me relent & do the last cuts with a grinder. Tires are ridiculously tough, not the rubber, the wire. I'm suffering from smoke inhalation & some kind of shaking condition in me arms but the Dewalt barely got warm. Bit of a beast.

Basically Mark if you got an honest life expectancy from your drill's batteries, there is no amount of black magic that is going to restore them! They are fucked for a good reason. I have tried the defibrillation and the freezing on a couple of lots of batteries in the past to no avail.

Nice. A good debunking, thank you. I reckon the drill has done it's fair share of work. But black magic? I keep hoping.
