I succeded in removing one strip but the other broke of, i went on with a credit card as suggested to unstick the other half of the batttery and it kindof worked, but then i used a plastig knife to lossen the remaining adhesive strip underneath the battery and accidentally cut throught the metal shielding of the battery, then i smelled a strange sweet smell coming out of the battery. Immediately put the battery in the backyard, maybe its gonna explode….
