I am seriously thinking of a battery refill business for a living. It
would be most likely a one-man shop by myself. I thought the refill is
one way of using our resource safely and economically if properly
serviced and managed. Even though I studied the electronic engineering
in college many decades ago, this energy/battery industry is totally
new to me.

I suppose there are basic steps in doing this: Opening the battery pack,
disconnecting the circuitry, replacing batteries with new ones after
some welding work, connecting the circuit, and sealing the seams. I
have, however, no idea on the complexity of each step, type of tools
and machines.

The trouble is that replacement cells of good quality usually cost more
than a complete battery for the most common things like cordless drills,
phones, etc. Although they will often make a cheap tool work rather better
than new ;-)

You have two options. Maker's packs have welded connections - the heat
generated by slower soldering may damage them. But so called tagged cells
are available in the common sizes, and these may be soldered. The casing
can be simply glued - if you can open it in the first place.

Would you be kind enough to give me a piece of advice on this business
technically or non-technically or business-wise. Every information,
experience, warning, advice or threatening from you will help me a lot.
Thanks a lot!

The main problem is that any maker of the things that use this type of
battery buys them by the millions and gets bulk discount. You'll be buying
only a few at a time - given the vast range - and will have to pay many
times their price. So will really be limited to economic repair of
specialist types where the overall sales are low.
