Direct replacement for Dell Latitude and Precision

The PISKEKAT RJ40G is a new 63Wh laptop battery built for Dell Latitude 14 5420, Latitude 15 5520 and Precision 15 3560 systems. It matches the original RJ40G, P137G, P104F and related part numbers so owners can swap the pack without adapter changes. The box includes the battery, two screwdrivers and an instruction sheet.

Limited to 15.2V 4-cell chemistry and listed models

This pack delivers 15.2V from a 4-cell layout and carries CE, FCC, ROHS and UL certification. It fits only the Dell series named in the compatibility list; other Latitude, Precision or vendor notebooks use different voltages, connectors or firmware checks and will not accept this unit. The rated cycle life is up to 1000 recharge cycles.

63Wh capacity decides runtime

The single figure that determines whether this battery meets a user’s mobility need is the 63Wh rating. A lower-capacity pack will give less run time per charge, while a higher-capacity alternative — if one exists for the same chassis — would add weight and cost. Buyers should confirm their original battery shows 63Wh before ordering.

Questions about this item

Which PISKEKAT RJ40G capacity matches my Dell Latitude 5520?

The RJ40G is supplied as a single 63Wh, 15.2V, 4-cell pack; no other capacities or voltages are offered for this model.

What does the 63Wh rating deliver in daily use on a Latitude 15 5520?

63Wh at 15.2V typically provides several hours of mixed office work on a Latitude 15 5520; actual runtime varies with screen brightness, workload and power settings.

What connector standard does the RJ40G use and what does it limit?

The battery uses the proprietary Dell RJ40G connector, so it fits only the listed Latitude 14 5420, Latitude 15 5520 and Precision 15 3560 models and cannot be used in other Dell or non-Dell laptops.
