It's not clear from these instructions how to actually disconnect the battery's wires from the main board... can you provide some guidance there?

PLS ANSWER MIKES QUESTION. You cant just remove the battery without disconnecting a wire which seems fragile so I can not go any further without this instruction. sighhhhhhdsgkhdsf;gklfxgbl;dfkbn; so annoying.

I replaced the battery, no problem Thank you Jake Van Loon and 4 others. My current problem is - in the process of replacing the battery the thin white strip that comes down from the top became disconnected. I notice in Step 4 of the Battery instructions that the strip is attached but in Step 5 is isnt. Can someone explain to me just how to reconnect that. Please. Any help is truely appreciated.
