Get a nice Hakko or Weller and you will be happy for a very long time. However, they are far more expensive so maybe not for everyone.
Depends on the level of competence. Anyone would themselves judge that it may be beyond their capabilities. For example I'm not the world's best SMD solderer, so I abstain from messing about with SMD stuff.
I would not advise anyone to try and open any laptop battery ! They are glued together for a reason ! If you are experienced at desoldering and changing over 18650 cells that are inside, fair enough ! If not it's one of the worst replies 'Of advice' i've seen on here ! maxmix
its expired but i just oredered the same one for £16.99, you just need to change the seller in options :) :) decided to cancel multimeter that I ordererd before as this is bargain :D Edit, I can see its back order now.
The Battery have only 2 wires red and black attached to motherboard :)
