This page is designed for Toshiba and Dynabook laptop users who want to check the real health of their battery.
Windows can generate a detailed battery report using powercfg /batteryreport.
You then upload the report here to see an easy-to-understand health estimate and replacement advice.

How to generate a Windows battery report on your Toshiba / Dynabook laptop
The battery report is created by a built-in Windows tool called powercfg.
It works on most Toshiba and Dynabook series, including Satellite,
Satellite Pro, Tecra, Portégé, Dynabook Satellite Pro,
Dynabook Tecra and other business / consumer models.
Here are a few common ways to generate it:
Method 1 – Command Prompt (recommended)
- Press Windows key, type cmd.
- Right-click Command Prompt and choose Run as administrator.
- In the black window, paste this command and press Enter:
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"
After a few seconds, Windows will create a file called
battery-report.html on your desktop.
Method 2 – PowerShell or Windows Terminal
- Press Windows key, type PowerShell (or Windows Terminal).
- Right-click and choose Run as administrator.
- Run the same command:
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"
This does exactly the same thing as Method 1, just in a different shell.
Method 3 – Create a reusable shortcut (optional)
If you check battery health frequently on your Toshiba or Dynabook laptop, you can create a small script:
- Create a new text file on your desktop and name it for example
toshiba-battery-report.cmd. - Edit it and put this single line inside:
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"
- Save the file and double-click it whenever you want to refresh the report.
Every time you run it, Windows will overwrite battery-report.html with the latest data.
Common Toshiba / Dynabook laptop battery problems this tool can help you understand
The Windows battery report contains detailed information such as
Design capacity, Full charge capacity and sometimes
Cycle count. By comparing these values, you can understand many typical
battery issues on Toshiba and Dynabook laptops:
-
Battery drains quickly on Toshiba Satellite / Dynabook Satellite Pro –
If full charge capacity has dropped far below design capacity (for example < 60%),
your laptop will run out of power much faster than when it was new. -
Toshiba or Dynabook shuts down suddenly at 20–30% –
A heavily worn battery can no longer provide stable power at low charge levels,
causing sudden shutdowns or black screens when unplugged. -
Battery stuck at 60–80% (or not charging to 100%) –
Sometimes this is due to battery protection or eco settings; in other cases,
the real full charge capacity has already decreased significantly. -
“Plugged in, not charging” on Toshiba / Dynabook –
This may be related to the AC adapter, DC-in jack, firmware or power profiles.
However, if the battery is very old or has a high cycle count,
it can also fail to accept charge properly. -
Battery not detected on a Toshiba laptop –
If Windows does not see the battery at all, it may be a serious battery or mainboard issue
and replacement is usually required. -
High cycle count (many charge cycles) –
Many Toshiba / Dynabook batteries are designed for roughly a few hundred full charge cycles.
If your cycle count is very high, noticeable wear is expected. -
Battery swelling (bulging bottom case, lifted touchpad / keyboard) –
This is a safety issue. If you see any physical swelling on your battery,
stop using it and replace it immediately.
Our online checker reads the key values from your Windows report and gives you
a simple health estimate specifically for your Toshiba or Dynabook laptop,
so you can decide whether it is time to replace the battery.

How to understand your Toshiba / Dynabook battery result
The tool compares Full charge capacity with Design capacity
and calculates an approximate health percentage:
-
80–100% – Good: Your Toshiba / Dynabook battery is in good condition.
For everyday work, study or light entertainment, you can continue using it without urgent replacement. -
60–79% – Aging: Noticeable wear. If your laptop runtime is already too short
for meetings, travel or daily use away from the socket, a new battery will bring a clear improvement. -
Below 60% – Poor: The battery is heavily degraded.
We generally recommend replacing it to avoid sudden shutdowns and to restore normal runtime when unplugged.
This percentage is an estimate based on the information Windows provides.
Different Toshiba / Dynabook models and usage patterns may behave slightly differently,
but it is a very useful starting point when deciding whether to buy a new battery.
Next steps if your Toshiba / Dynabook laptop battery is in poor condition
If the health percentage is low, or if you already experience sudden shutdowns,
short runtime, or charging problems on your Toshiba / Dynabook laptop, a replacement battery
is usually the most effective solution.
When you look for a new battery, pay attention to:
- Exact Toshiba or Dynabook laptop model (for example: Satellite, Satellite Pro, Tecra, Portégé, Dynabook Satellite Pro, Dynabook Tecra, etc.).
- Original battery part number printed on the old battery label.
- Voltage (V) and capacity (Wh or mAh) that match your original battery specifications.
- Reliable supplier, clear warranty and return policy.
If you need help finding the right replacement battery for your Toshiba / Dynabook laptop model,
you can contact us with your model name and (if possible) a clear photo of the original battery label.
