[Q] [P3110] Battery issues, what do? topic

Having some issues on my aging Galaxy Tab 2 (GT-P3110). The battery does not seem to accept a charge, nor does it seem to hold what charge it can get. Any possible fix for this, even if its temporary? I just want to be able to move about 1GB of pictures and music onto an External SD before laying this old girl to rest, if that is the case.

Running Android-Andi's CM12, with TWRP recovery, if thats any help.
