The battery is a laptop component that naturally wears out over time. If your laptop runs for a much shorter time on a single charge, shuts down at 30–40% battery level, or only works when plugged into the charger, the battery most likely needs replacement.

At our Laptop Repair Service Warsaw (Ochota, 132 Grójecka Street), we provide professional laptop battery replacement for all major brands – Dell, Lenovo, HP, Asus, Acer, Apple and more. Every repair starts with free diagnostics.

How does a laptop battery work?

Modern laptops use lithium-ion (Li-Ion) or lithium-polymer (Li-Po) batteries. They consist of battery cells connected to a control board (BMS – Battery Management System), which manages charging, discharging and temperature control.

Over time, the battery cells gradually lose capacity. This is a completely natural process – every battery has a limited number of charge cycles. Once this limit is reached, battery life starts to noticeably decrease.

Symptoms of a worn-out or damaged battery

The most common symptoms indicating battery replacement is needed:

  • the laptop only works when connected to the charger
  • the system displays a “Consider replacing your battery” warning
  • the battery charges very slowly or does not charge at all – this may also indicate a damaged charging port
  • the laptop suddenly shuts down despite showing remaining battery percentage
  • the casing around the battery area becomes swollen
  • battery life dropped from several hours to only a few minutes

If the battery is swollen, you should stop using the laptop immediately – it may damage the casing, touchpad or even the motherboard.

Causes of battery failure

The most common causes include:

Natural wear and tear – Every battery has a limited lifespan. After 2–4 years of regular use, battery capacity usually drops significantly.

Laptop overheating – Often caused by lack of cooling system cleaning. High temperatures accelerate battery cell degradation. That’s why during battery replacement we often recommend cleaning the cooling system as well.

Using the wrong charger – Laptop chargers with incorrect specifications may cause unstable charging and damage the battery electronics.

Deep discharge – Leaving the laptop with a fully discharged battery for a long time may permanently damage the battery.

Does your laptop battery drain quickly or only work when plugged in?

We’ll check the battery condition and select a compatible replacement or original battery.
