Sorry for crosspost but r.b.e doesn't seem to see much traffic these days.

I am trying to rebuild several old handheld VHF battery packs that seem no
longer commercially available. The radios themselves seem fine and are
certainly OK for my application. I took the batteries apart and tried a
temporary fix with standard alkaline AA cells, taping aluminum foil in
place
to make series connections. The radios seemed to like this so I bought a
quantity of the corresponding NiMH rechargeable AA cells to make a
permanent
repair.

Problem is I am not at all sure how to secure a conductor from "plus" to
"minus" with the cells to make a strong and long-lasting series
connection.
Is there some kind of conductive adhesive or conductive film that can be
used for this application? Larry, where are you when we need you (weak
humor)?


Use copper wire and solder it to the top and bottom's of the respective
batteries. The trick is to not get the battery ends too hot. Use one of
those fancy butane torches that have a tiny flame. They will melt and stick
the solder without harming the battery. Practice on a couple dead batteries
first to get your technique down. Use rosin core solder.

Our local "Batteries Plus" (USA) will weld tabs onto customer's batteries
for a small token payment ($2 last time I had a dozen done).

Strange how at least one subscriber here says "Don't do it!" yet it's plain
that it's done all the time. I guess what some people believe is THEY can't
do it while a so-called professional can. What they're really saying is
don't do it because *I* can't do it and I don't want you doing it because
YOU would make ME look bad. They don't believe they have the skill to do a
simple job. They don't have the guts to even try it on a dead battery. They
would have YOU be the same. How pathetic is that? And these people claim to
be sailors? Yeah right! Probably have to pay somebody to repair a tear in a
sail, or put an eye splice in doublebraid, or wire up their GPS, or put a
coat or two of paint on their boat's bottom, or install new standing
rigging, or install new parts in the head pump.

Stupidity, laziness, fear, sloth and ineptitude is all that one encounters
in this world anymore. A bunch of dependent people all queuing up to pay
somebody else with borrowed money to do things they should learn how to do
themselves. Disgusting and pathetic!

There are good reasons not to do it yourself here.
I can solder - but I also know that such a procedure will hurt the
battery, and I also know that solder joints are susceptible to failing
under vibrations, corrosion etc.
Just because something can be done and it works first does not mean it
will be reliable and live long. Qualities I tend to look for if it is
installed on my boat.
Of course everyone is free to use their preferred solution. I just do
not recommend soldering for this purpose.
It is just like I'd never use screw terminals to join conductors on a
boat.

Whew.

The pros don't solder, they spot weld the tabs on.
