KingSener RJ40G laptop battery 15.2V 63WH for Dell Precision 3560

Replacement battery for Dell Precision 3560

The KingSener RJ40G is a 15.2V 63WH lithium-ion replacement battery built for the Dell Precision 3560 series. It matches the original 01K2CF and 075X16 part numbers for direct compatibility. The pack uses high-quality cells and a protected circuit board to deliver stable capacity. It arrives new and ready to install.

Physical fit and daily handling

The battery shares the exact dimensions of the factory unit so it seats without modification or force. A black Li-ion shell houses the cells and PCB, keeping the profile identical to the OEM design. No extra brackets or adapters are required during the swap. Routine care follows standard lithium-ion practice: avoid prolonged adapter connection while running, keep the pack away from heat and humidity, and store above 80% charge if removed for a month or longer.

Capacity and chemistry limits

Rated at 15.2V 63WH, the pack cannot exceed this energy ceiling regardless of workload. Lithium-ion chemistry degrades with deep cycles, high temperatures and long-term storage at full or empty states. The supplier advises two to three full charge or discharge cycles at low current to settle the cells initially. Users who need more runtime than 63WH provides will require a higher-capacity alternative or a secondary power source.
