Replacement battery for IdeaPad Y series

The KingSener L14M3P24 is a new lithium-ion replacement battery built for Lenovo IdeaPad Y700-14ISK, Y700-15ISK, Y700-17ISK and Y520-15IKBA models. It uses three cells rated at 11.52V and 4050mAh to deliver 45WH of energy. The physical dimensions match the original pack so installation requires no modification.

Sustained discharge and cycle care

High-quality cells and a reliable PCB maintain stable voltage through a full work session instead of sagging after a short burst. The supplier advises two or three full charge-and-discharge cycles at low current when the battery is first used. Avoid leaving the AC adapter connected continuously while the battery is fitted, as prolonged trickle charging can degrade long-term capacity.

Capacity ceiling and storage limits

The 45WH design capacity sets the hard ceiling for runtime; the battery cannot store more energy than this rating. For shelf storage, keep the pack above 80% charge and top it up at least once a month. Do not expose the unit to hot or humid environments, and never disassemble, crush, puncture or dispose of it in fire or water.

Questions about this item

Does the 4050 mAh 11.52 V pack run warm or draw extra power during long sessions?

The 3-cell Li-ion design matches the original voltage and capacity, so heat and power draw stay within the levels the laptop was built for.

What must I already have to install this battery?

You need a compatible Lenovo IdeaPad Y700-14ISK, 700-15ISK, 700-17ISK or Y520-15IKBA and a small screwdriver to open the battery bay.

Will this replacement fit the same bay as the original battery in my Y700?

Yes, it is built to the same dimensions as the factory pack for the listed models, so it seats without modification.
