The best way to jump charge a battery is to take it apart, and test and boost the individual cells.
Barring that, jumping voltage across the entire pack will also charge the cell(s) that are lower than the rest, hopefully getting them close enough that the charger can balance them.
If the cells have been too low for too long, they'll be damaged, and may not take or hold a charge again, or just have lower capacity.
