The Dell RRJDX is a rechargeable lithium-ion battery that provides portable power for a laptop. Dell lists its rating as 42 Wh, 11.4 V and 3500 mAh, which identifies this variant among batteries with different part numbers or ratings.

For the 3-cell, 42 Wh configuration described in the Latitude 5490 manual, Dell gives dimensions of 181 × 95.9 × 7.05 mm and a weight of 210 g. These figures specify that documented configuration.

As an internal power source, the RRJDX lets a compatible laptop run away from an outlet. Its capacity and electrical rating help identify the battery configuration when choosing a replacement for an installed battery that needs replacing.
