2-power pääakku Lenovo ThinkPad L480 20LS - akku - 50 mAh (2P-L17C3P52)

When the original cell inside a Lenovo ThinkPad L480 begins to fade, this 2-Power main battery pack restores the all-day mobility that business notebooks are built for. It is not a universal afterthought: the 2P-L17C3P52 is engineered specifically for the L480 chassis, so the fit, the connector, and the smart communication are all native. The 50 Wh lithium-ion stack delivers a genuine 11.55 V nominal output and is built around a 3-cell layout that balances weight against runtime. Unlike cheap third-party packs that rely on basic protection only, this unit includes a smart chip that talks directly to the ThinkPad, keeping the battery gauge accurate and the charging curve safe.

Highlights

• Direct replacement for Lenovo L17M3P52 and L17L3P51 batteries
• 50 Wh capacity with 11.55 V output for consistent performance
• 3-cell lithium-ion construction with smart chip technology
• Built-in overcharge, over-discharge, over-current and short-circuit protection
• CE, RoHS and FCC certified for safety and environmental compliance
• Up to 500 charge cycles for long service life

In daily use

Slide the pack into the ThinkPad L480 (20LS or 20LT) and the system recognises it immediately. The smart chip keeps Windows or Linux battery reporting precise, so you are not surprised by a sudden shutdown at 20 percent. A full charge typically restores enough runtime for a full working day of documents, spreadsheets, video calls and light browsing. The black housing matches the laptop's underside, and the mechanical latch is identical to the original, so there is no wobble or gap. The pack is rechargeable and can be topped up using the standard Lenovo AC adapter or a USB-C charger with the appropriate cable.
