2-power 2P-L15C3PB1 - akumulátor - batéria 46 mAh 11,4 V

When a laptop battery begins to fade, it is rarely the device that fails first—it is the power source. The 2-POWER 2P-L15C3PB1 steps in as a direct replacement that restores dependable runtime without forcing a new machine purchase. Built around a 3-cell lithium-ion core, it delivers 46 Wh at 11.4 V, matching the energy profile of many original batteries while adding a layer of protection circuitry that keeps voltage spikes and temperature extremes in check.

Highlights

• 3-cell Li-ion construction with 4035 mAh capacity for balanced endurance
• 46 Wh energy rating at 11.4 V—consistent output for everyday tasks
• Integrated safeguards: overcharge, over-discharge, overcurrent, and short-circuit protection
• Rechargeable design that fits standard laptop charging workflows
• Black housing with compact dimensions for a clean fit in compatible models

In daily use

This battery is meant to be forgotten once installed. It charges through the laptop's normal power adapter, holds a charge when the machine is off, and provides steady voltage during video calls, document editing, or media playback. The 46 Wh capacity translates to roughly the same screen-on time as the original cell, assuming similar usage patterns. Because it uses lithium-ion chemistry, there is no memory effect to manage—partial charges are fine, and the battery can be topped up whenever convenient.
