2-POWER pääakkupaketti Lenovo ThinkPad T480s 20L7 - akku - 44 mAh (2P-L17L3P71)

When your Lenovo ThinkPad T480s starts shutting down unexpectedly or the battery percentage drops from 50% to 5% in minutes, it's not a software issue—it's a tired battery. This 2-POWER main battery pack brings back the all-day endurance your ultrabook was built for, without the inflated price of an original Lenovo part. It's a direct replacement for the internal 3-cell lithium-ion battery in ThinkPad T480s models 20L7 and 20L8, matching the original 44Wh capacity and 11.52V output.

Who is it for

Road warriors, field technicians, and anyone who relies on a ThinkPad T480s away from a wall outlet. If your laptop is otherwise in great shape but the battery has degraded after hundreds of charge cycles, this pack is the most cost-effective way to restore portability. It's also a smart choice for IT departments that need to refurbish a fleet of T480s units without breaking the budget.

Tips

Before installing, discharge your old battery to below 25% and power off the laptop completely. Use a plastic opening tool to avoid scratching the bottom cover. After installation, fully charge the new battery to 100%, then let it drain to 5% and recharge to calibrate the battery gauge. For best longevity, avoid keeping the laptop plugged in at 100% for extended periods; use Lenovo Vantage to set a charge threshold of 80% if you mostly work docked.
