Need a bit of advise from a battery guru

Figured I'd post here rather than on another site cause I trust everyone's words here and it has to do with 18650's anyway.

Awhile ago I bought a roomba battery on ebay but within a few months it was dead and to make a long story short, it went into a drawer & forgotten about.
So recently I tore into the battery which contains 8 LGABB41865 2600mAH Bats every single one read 0 volts.. Almost recycled them all till I found a post yesterday about pushing the fuse down under the + contact.

So my question is this do I 100% NEED to use Nickel strips to join them back together ? Or can I just use regular wire and solder them together.? I know its not recommended but I have no idea where to find Nickel strips anywhere near where I live..

Thank You
Peace

fix em if you choose BUT they still wont be suitable for vaping at any wattage drawing more than about 2 or 3 amps. Fine for flashlight though.

As HondaDavidson said those are a 4 amp battery as I recall. And should not be used for vaping.
Fuse down under + contact?
Yes people do solder them together with wire, but I do not really recommend it.
The spot welding with the thin strips is the best way.

I have some of the same battery I salvaged from a laptop pack. I use them in a flashlight.
And they have labels on them saying FLASHLIGHT, because they look just like my LG HG2 batteries I use for vaping.

No no not gonna use them for vaping they're going into our roomba vacuum the one it has in it is almost completely toast.
