You would need to disassemble the pack and individually test 50 5 cell sticks for capacity, internal resistance and self discharge.

This thread describes building a charger to replace the jump starter removed from 09+ models:

It can be also used to grid charge if you provide an external cooling source. I've done it many times by removing the battery cover and laying a box fan on top of the battery to blow air down through the cells. 24 hours of charging is needed.
