Default DeWalt 9116 charger R49

This DeWalt 9116 charger has had battery packs forced into it
repeatedly and strongly enough to crease-open board foil in the area
and crack R49 ntc thermistor in half. The thermistor chip fragment
remaining in the R49 half-package still measures ~77K, but standard
values suggest this should be sloser to either 13K, 25K, 37K or 120K
at room temperature.

So what's the correct normal R49 value for replacement?

As a result of the physical damage, other parts are also damaged, but
I believe these have been fairly easy to track down, identify and
replace.

Remove remnant and solder on a pair of wires , lead out to a 100K pot and
"suck it and see" and post back the result to wwwland
