2-power batteria principale Lenovo IdeaPad S540-13ITL 82H1 - batteria ricaricabile - 46 Wh (2P-L19M3PD3)

When your Lenovo IdeaPad S540-13ITL (82H1) can't hold a charge through a full afternoon of work at a café or a long flight, this 2-Power 46Wh lithium-ion battery brings it back to life. It's a direct replacement for the original pack, fitting the same bay and connecting to the same internal header, so you can swap it in with just a small Phillips screwdriver and a few minutes of careful work.

Why choose it

This replacement pack uses grade A cells and a smart protection circuit to deliver stable output and safe charging. It restores the original runtime you expect from a 13.3-inch ultrabook, so you can leave the charger at home for a full day of meetings, lectures, or travel. The 12-month warranty covers manufacturing defects, and the battery meets CE and RoHS standards for safety and environmental compliance.

Ideal use cases

• Reviving a laptop that shuts down at 30% or only runs on AC power
• Keeping a spare battery charged for hot-swapping during field work or long events
• Extending the life of an otherwise healthy IdeaPad S540-13ITL instead of replacing the whole machine
• Reducing downtime for students, freelancers, and business travellers who depend on their laptop all day

Good to know

Before ordering, confirm your laptop's model number on the bottom label: it should read "IdeaPad S540-13ITL" or "82H1". The battery is shipped in protective packaging with a partial charge; fully charge and discharge it once or twice to calibrate the fuel gauge. Installation is straightforward, but if you are not comfortable opening the case, a local technician can do it in minutes.
