confused charging lipo

[Appie53]

Dear Guy's, I have some problem with one lipopack 5000-40c.
When I try to charge balanced, 5amp drops to 0.7amp after a some seconds.
So lipo when full, and I try the store function after a some seconds I get the beep its done?? Checking with a voltmeter is says 8.55volts.
Now I confused, is this pack dead, full or stored??

Thanks for your advice,..........Appie.
