KingSener L18M6PD1 48WH 11.46V laptop battery for Lenovo ThinkPad X390 X395 X13 1st Gen

Replacement Battery for ThinkPad X390 X395 X13

This KingSener L18M6PD1 lithium-ion pack replaces the original Lenovo batteries used in ThinkPad X390, X395 and X13 1st Gen models. It matches the 11.46V voltage and 48WH capacity specified for part numbers 02DL017 through 02DL020 and SB10K97655 through SB10K97658. The black unit is supplied new and carries a one-year warranty. It is not suited for laptops outside these listed series or for users who need a higher-capacity alternative.

Sustained Capacity Behaviour

The 48WH rating reflects the energy the cell can deliver under typical discharge rates seen during office work, video playback and light development tasks. Voltage remains stable at 11.46V across most of the cycle, so the system does not throttle prematurely when the load is held for several hours. Runtime will fall if the processor is kept at maximum turbo or if peripherals draw heavily from USB-C ports. Buyers who require all-day operation without recharging should note the fixed capacity limit.

Thermals Noise and Power Draw

As a passive battery there are no fans, pumps or moving parts, so acoustic output is zero and the pack adds no active heat beyond normal cell resistance during charge or discharge. Surface temperature rises slightly under heavy load but stays within the thermal envelope designed for the ThinkPad chassis. Power draw from the wall depends entirely on the attached AC adapter and system power management, not on the battery itself.
