Step 16
Place the desoldering wick on top of the existing solder ball.
Place the soldering iron on top of wick above the existing solder ball.
Hold the soldering iron in place until the solder melts into the wick.
Repeat the same procedure on the remaining two connectors.
Step 17
Be careful not to scrape the metal rings surrounding the connectors off the logic board. If you accidentally scrape these off, you won't be able to reconnect the replacement battery.
Use a metal spudger to carefully straighten the battery wires. Be sure to only touch one contact at a time.
Step 18
Pull the battery wires through the logic board to free the battery. If the wires don't easily come free, make sure the wires are straight and all the solder has been removed.
