hi today we're gonna have a little chat about drill batteries this is I this is my old 14 4 volt Mastercraft drill from Cambodian tire it takes these pretty normal NiCad battery packs these rechargeables my kids are great when they're new when they get old they go to crap and they develop a memory and they get all sulfated and they stop working like this one it just came off the charger so believe it or not what I'm going to do to try to rejuvenate my battery pack is employ my welder which is a little power fist from Princess Otto and it's a slightly more adjustable version with wire speed adjustments and heat adjustments i think they sell a cheaper version that doesn't have hardly any of this stuff this was on sale for 200 bucks at some point and it's probably the most - of the most fun I've had with 200 bucks it in the shop ever a lot of fun recommend you try it out but yeah so we're going to get some power fist on this battery and see what happens and there's no fists like a power fist first thing we need to do is check out the polarity of the welder I'll be right back to do that okay so welcome the trapdoor in side door on the welder just like one of those antique car hoods and you can see here this is the wire feed roller it's the wee little spool meg wire it's a flux core wire so I don't have any welding gas but the welder is convertible to guys so I'll do that sometime problem any real welders will laugh at the size of my wire roll it's a 2-pound roll down here they have this lovely helpful diagram which tells me that since I'm using no gas shielding my clamp is the positive side of the welder that's good to know since I'm in here I'm actually going to detention the scrap video I'm going to detention this thing here which puts tension on the feed so I don't really need the wire to feed while I'm doing this I just need the electricity alright this is the working clamp to the welder here since this clamp is a not a great conducive shape for what I'm trying to do or doesn't the jaw doesn't actually open wide enough I'm borrowing the lead off of a little battery booster packed and I picked out of the garbage and this you can see is nestled in this little plastic part here the casing and on the positive connection side of the battery that leaves this side open the negative side open for me to hit with the wire feed gun and whatever that's called I don't know I'm bad welder sorry so I can zap the crap out of this and I'll try to get a little video of me zapping the crap out of that a few times see if we can wake the sucker up okay since I am working with a welder and a battery neither of which were made to work together as potential for battery explosions and welding sparks I'm going to be using proper welding safety gear or semi proper with my full face mask proper thick welding gloves and my jacket that's held together with duct tape perfect safety equipment it goes nothing okay here we go battery pack hot off the charger it's actually slightly warm to the touch here we go our uncle let's see from a pack that wouldn't even take a charge what we have here not bad not bad at all let's turn her up a little so it doesn't trip the clutch yep that does the trick so there you go you can zap the hell out of your batteries carefully with a welder and you might get a little more life out of them that's your tip of the day check you later
