You're almost certainly out of luck. A lithium battery that hasn't been charged for over a year is pretty likely to be suffering from a terminal case of death.
A hint for the future: if you're not planning to use a battery for a while, charge it to around the 40-50% level, and top it back up to that level every month or two. Any battery will slowly discharge with time if not used, and once the charge in a lithium battery falls below a certain critical level, the battery can't be recharged.
The good news, if you care about it, is that the battery in a KK can be easily and cheaply replaced.
