Hello AAC

I am trying to sold these batteries together, but I don’t know how to sold on the button and top of the batteries. The soldering tin won’t stick with the wire to it. I really hope some of you can help me with this problem, thanks

 

hi,
What are the battery case sizes eg: C, AA, AAA .?
E

 

The batteries are lithium batteries, I took them from an old laptop battery-pack

 

hi Rune,
I have end soldered to NiCd and Alkaline, but would not consider soldering to a Lithium battery, it is a very unforgiving metal when heated.
Will those cells fit into a regular battery holder.?

Oh, yes I guess, so what you recommend me is to find some battery holders, ofc., didn't even think about that. It's because I took a Power Bank and wanted to add the old laptop batteries to it, but yea, as you say I should get some battery holders.

 

hi,
You can buy 3 cell or 4 cell battery holders for most of those smaller cells.

Thank you!

 

Get a file or screwdriver and scratch the terminals, then you can solder them .

 

There are some links out there to some that have made simple capacitor discharge Stud Welders, this is how the manuf. do it.
The problem with soldering, is getting sufficient heat on the terminal to bond the strip.

I use an old, diamond coated, fingernail file. It only takes a few scratches to damage the surface enough to get solder to wet it.

 

I soldered wire to a bunch of NiMh batteries without problem by first putting some rosin flux on the battery ends and wire.

 

I used plumbers paste, a bit aggressive, it works, but its important that you thoroughly clean the joint afterwards.
Use a 60Watt iron with a chisel tip in order to heat the joint area quickly.
