Soldering to battery terminals? |
|
|
I've attempted modding my Crest Spinbrush with a wall-adapter power supply.
I quickly realized that solder does not stick to the battery terminals. It
looks like they are standard battery terminals, and I'm not sure what metal
they're made of, though it looks like stainless steel.
| Quote: | Is there any way of connecting wires to the battery terminals?
|
I was thinking I could try bending the terminals up and then attaching
alligator-style-clips to them, but it isn't a reliable connection for
something that's going to be sealed up and bumped around.
I'd rather not have to break the plastic covering open. Thanks for any
advice.

Try scrubbing them with sandpaper, then smear some soldering paste onto
where you roughed up the surface with sandpaper. Solder as usual.
Good Luck

It does if you do it right.
Abrade with sandpaper.
Apply flux
Use a big iron with lots of thermal mass in the bit
Tin the cell and cool it quickly with wet cloth
Tin the wire.
Apply more flux to cell.
Solder/flow the wire to the cell
It's even possible to solder two cells end-to-end with no wire if you know
what you are doing....
