The pic is the sub-C that are in the pack. They are Ni-Cd Liang Ye SC1300mah 1.2v. I took a 15 pack from a different device but the same configuration, that didn't charge. I tried it in my current but it didn't work either, so I have chopped the packs up into sets of 2. I am charging them in an eveready multiple charger, it charges D, C, AA, AAA and 9v Ni-Cd. the Ni-Cd battery was made to outlast the nimh competition... I need to know whats wrong.. and why my Ni-Cd charger is heating up with 1.2v sub-c 1300mah bats.
