Questions about this item

What Dell Chromebook model must I already own for this 5R9DD battery to fit?

This battery fits the Dell Chromebook 11 3120 P22T. It replaces OEM part numbers 5R9DD, KTCCN, 0KTCCN and XKPD0.

Will the 11.1V 43WHR capacity work with the original charger that came with my 3120?
