Understanding Battery Wear
Laptop batteries lose capacity gradually over time. This is a chemical process inherent to lithium-ion cells and isn't caused by anything the user does wrong — it simply happens through charge cycles. Most laptop batteries are rated for somewhere between 300 and 500 full charge cycles before capacity starts to drop noticeably, though actual degradation rates vary by model and usage habits.
When a battery has lost enough capacity that it can no longer power the laptop for a useful period, or when it begins showing other symptoms like swelling or not charging at all, replacement is the practical solution.
Common Symptoms
- Runtime has declined significantly from when the laptop was new
- Laptop shuts off unexpectedly even when the battery indicator shows charge remaining
- Battery won't charge past a low percentage
- System reports battery health as "Replace Now" or similar warning
- Battery appears swollen (visible bulge under the palm rest or touchpad area)
- Laptop only works when plugged in
A Note on Swollen Batteries
Battery swelling (caused by gas buildup inside the cell) is worth taking seriously. A swollen battery can put pressure on other internal components and, in rare cases, poses a safety risk. If you notice any physical deformation of the bottom panel or difficulty closing the laptop, it's worth having it looked at without delay.
The Replacement Process
We first check the battery health using diagnostic software to confirm the fault and assess how degraded the cell actually is. For batteries that show poor health or are no longer charging, we source a compatible replacement that matches the original specifications — same voltage, same capacity where possible, and correct connector type.
Some laptops have user-accessible batteries that can be swapped by removing a panel. Others have batteries glued or integrated into the chassis, which requires more involved disassembly. We'll let you know which applies to your model.
After Replacement
Once the new battery is installed, we run a full charge cycle and test runtime to verify it's performing as expected. We also check that the charging circuit is functioning correctly, since a faulty charging port or power management issue can sometimes be the root cause rather than the battery itself.
