Also departed from procedure immediately after STEP # 4 as per JOEL’s recommendation …used a small chunk of fishing line and it worked sans solvent…easily ! Spudger worked quite well to initially position the string /line & the ifixit ( ‘credit’ ) cards were nice for final dislodging of each battery segment from the last bits of residual gooey adhesive , AFTER working the fishing line back & forth down the length of the battery as much as possible. With the old battery out of the way, I used a razor blade to clean out the remaining bits of adhesive gunk. ( Decided NOT to use solvent here, either.) Took me every bit of 1-hour.

One thing that helped ,too, was a cheap pair of cotton gloves coated on the palm side w/ latex. This kept my fingers comfortable from the pressure of the fishing line & allowed more of a range of force …since I wasn’t wincing from saw-cutting myself !

Stephen’s visionary suggestion to use 10 mm open end wrench (also called 10 mm ‘combination ‘ wrench…) proved an EASY way to pry open the casing !

Hold the case w/ left hand ; with ‘cord-winding flaps’ facing up .

Flip open the ‘cord-winding flap’ nearest your left hand thumb which is gripping the case.

Insert open end of your handy 10 mm wrench ( I tried 9, 11, & 12 mm wrench to compare …the 10mm is best ! ) into the newly exposed space under the just opened ‘cord-winding flap’. Pinning the ‘pointed end ‘ of wrench into corner under the flap which is about to become a PIVOT point… gently rotate the wrench about 30 degrees away from you , UNTIL the outside rounded shoulder of the wrench comes into contact w/ the OTHER inside edge of the case !

While keeping the wrench pinned firmly against its ‘pivoting’ corner… CONTINUE trying to slowly rotate the wrench away from you… You are now PRYING the case open !

Saved me on this one… Thanks,Stephen !- JJoslin ( Detroit, Mich.-south of Canadian borderline)
