Does anyone know the name or specs of the battery connector for an Apple Macbook A1342? I'm trying an experiment to see if I can recharge a bad Macbook battery with a good one. I'm thinking I'll buy one of those Dupont kits and try to rig something up. But I'm not sure if that's the right connector. I'm new to this and would appreciate any feedback. I

An experiment must always have a reason, what do you think is different about using a battery to supply current to a dead battery than using a battery charger?
Save your self the risk of explosion, it will not work.

Apple designed Macbooks not to recognize the batteries once they fall below a certain voltage. I think they set this threshhold too high and so many pretty good batteries "fail" when maybe they don't need to. My idea is to try to charge the voltage of the battery a little higher so that it can once again be charged by the Macbook. I can't use the Macbook to get the battery to this threshhold. I have to devise my own charger.
Thanks for any thoughts on how to do this.
WattsThat:
Those “DuPont” jumpers are useless for anything other than logic signals. The actual wire diameter is 34 awg or less, only good for sub 100 milliamp amp range currents. If you put any appreciable current through them, they’ll melt or worse, catch fire if they don’t fuse open with a loud pop.Oh, yeah, a another thought. I wouldn’t muck about with fully charged li-ion batteries dumping them into dead ones. Thats a really good way a good way to burn your house to the ground.
Thanks for your thoughts on Dupont connectors. Didn't realize that. Can I use a thicker gauge of wire or a different connect?
Do batteries really explode or catch on fire? I thought that was just something that you read about on the internet. It happens in real life? 
If perhaps you are thinking of the old way to revive NiCAD batteries by applying a spike of very high current. That does not apply to the new batteries.
Regarding explosions (or at least fires) when the internal temperature of the new batteries reaches a certain temperature the batteries start to conduct internally raising the temperature which makes them conduct internally more .......etc.

Do not under any circumstance mess around with LiPos unless you have a very good understanding of electronics and batteries in particular. Lipos can and do explode.

You did not realise the wire in Dupont connectors is very thin ?????
See the comment above.
Dupont connectors them selves can handle quite a lot of current.
Its cheap premade hookup wires that use thin wire, the decent sort can handle an amp or so IIRC.
I suspect some of the cheap stuff uses CCA wire which I believe is not rated for crimping - I certainly
would worry about corrosion and thermal expansion problems with aluminium wire.
