Dell DJ1J0 Replacement Battery Review
Dell DJ1J0 replacement battery, the 42Wh 3-cell 11.4V pack for the Dell Latitude 7490 and Latitude 7480, also used in the Latitude 7280, 7290, 7380 and 7390.
Dell's Latitude 7490 manual lists a 3-cell 42Wh and a 4-cell 60Wh battery. Parts-People sells the 42Wh pack as the Dell OEM DJ1J0 and lists C27RW, PGFX4 and 9W9MX as older codes for the same part. The 60Wh option is Dell F3YGT.
