Is your laptop battery draining fast, not charging properly, or shutting down without warning? At Bitmaster PC Repair, we help customers in Punavuori, Helsinki determine whether a laptop battery replacement is the right solution — and if so, what battery is actually needed.
We do not keep laptop batteries in stock. This is intentional: laptop batteries are highly model-specific, and ordering the wrong one is a common and expensive mistake. Instead, we first verify the correct battery and availability based on your laptop’s exact model.
Common laptop battery problems
We see these issues weekly:
- Battery lasts only a few minutes
- Laptop works only when plugged in
- Sudden shutdowns at 20–40%
- Battery not detected or not charging
- Swollen battery or overheating
While these symptoms often point to a worn battery, the root cause is not always the battery itself.
Why laptop battery replacement is not always simple
Many modern laptops use:
- Glued-in or sealed internal batteries
- Model-specific connectors and firmware restrictions
- Charging and power-management systems that can fail independently
Installing an incorrect or low-quality battery can cause charging issues, system instability, or even physical damage. That’s why we always check compatibility first.
