Dell JPFMR Replacement Battery Review
Dell JPFMR replacement battery, the 42Wh 3-cell 11.4V short-cable pack for the Dell Chromebook 3100, Chromebook 3100 2-in-1 and Chromebook 3400.
Dell's Chromebook 3100 spec sheet lists a single 3-cell 42Wh 11.4V battery. Parts-People sells two versions that differ in cable length: this short-cable JPFMR and the long-cable Dell 51KD7. Check the cable on the battery you remove and order the same length. Older labels for this part include 7T0D3, 16DPH, 65N6H and 07GDY.
