Compatible Dell Latitude and Precision models
This 63Wh lithium-polymer battery replaces the original RJ40G unit in Dell Latitude 14 5420, Latitude 15 5520 and Precision 15 3560 series laptops. It matches the 15.2V voltage and 3941mAh capacity of the factory part. The four-cell pack fits the same chassis footprint as the original equipment.
Replaces lower-capacity 42Wh alternative
Dell ships two different batteries for the 5420 and 5520 platforms; this is the higher-capacity RJ40G 63Wh version rather than the 42Wh WY9DX variant. Buyers must verify the part number printed on their existing battery before ordering. Systems already using the 63Wh pack gain a direct swap without capacity loss.
Sustained runtime and cycle life
Rated for up to 500 recharge cycles, the pack delivers consistent output under continuous workloads typical of business and mobile workstation use. For initial conditioning, discharge to 5 percent then charge to 95 percent and repeat three to four times. Actual runtime varies with device power draw and usage patterns.
