Frequently asked questions

How can I be sure this battery is compatible with my Toshiba laptop?

The most reliable way is to check the part number (P/N) of your original battery. Remove the battery from your laptop and look for a label with a code similar to PA3817U-1BAS. If the code matches, this battery is the correct one. The laptop model can be misleading, as the same series may use different batteries.

Is it necessary to calibrate the new battery upon receipt?

Yes, it is recommended. To calibrate it, charge the battery to 100% the first time, then use it until the laptop shuts down due to low battery (approximately 5%). Let it rest for a couple of hours and then charge it back to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery.

What autonomy can I expect from this 4400 mAh battery?

Autonomy depends on your laptop's consumption (screen brightness, processor usage, etc.) and the equipment's condition. A 4400 mAh battery like this typically offers between 2 and 4 hours of office use or web browsing on a standard laptop. It is a capacity similar to many original batteries.

What warranty does it have and what do I do if it doesn't work or fit well?

The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it does not fit or does not work correctly, you have 14 days to return it. You can manage the return yourself or request a home collection for €8.90 in Spain and Portugal, which will be deducted from the refund.
