Bosch PSB 1800 LI 2 18v Combo Drill - Battery Fail and Repair

One of the battery packs failed on the Bosch drill which was odd since it has not had hard use but gentle regular use. Let's open the pack up to see if we can work out what failed. Bosch support did not offer any assistance either so pretty disappointed.
