Milwaukee battery fusible link? solder repair
« on: November 04, 2024, 09:38:39 pm »
..this guy hasn't filled me confidence - but i guess a version of this might do the job.

I will discharge the battery first.

Don't. At least salvage fusible element from automotive fuse (or put a whole fuse if it fits), or something like that. It's a serious risk of fire/explosion. YouTube dude is a dumbass for doing it, and thrice the dumbass for showing it to others with no safety warning. Also there seems to be corrosion on PCB which needs to be fixed as it's a hazard too.

I just used a 60amp Maxifuse by Littlefuse and soldered it in on my Dewalt 5 AH batteries.  You have to cut the blades off but in the end you do have power rating of your repair FWIW.

...a fix, with some surprises.

It was agreed a fuse [60A] soldered to the existing fusible plating area was the wise move.

...my little/fine Metcal soldering iron was happiest with this lead free soldering task.

..on the charger I got four lights sooner than I imagined, after those longer two hours discharging it at 1 -2 amps.  :palm:

..to check the battery i used my Makita impact wrench with a battery adaptor - with its torque adjustable, luckily for me I set it low to start with.
