Frequently asked questions

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

To confirm compatibility, remove the current battery from your laptop and check the reference printed on the label. If it exactly matches PA3634U-1BAS, this battery will work for you. The laptop model is not sufficient, as the same series of equipment can use different batteries.

Is it necessary to calibrate the new battery the first time it is used?

Yes, it is highly recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it with the battery until it is completely depleted and the device turns off. Finally, charge it back to 100% without interruptions. This process helps the system recognize the actual capacity.

What is the approximate autonomy I can expect from this battery?

The actual autonomy depends on your laptop's power consumption and energy settings. With 4400 mAh, this battery aims to match the duration of the original part when it was new. Generally, you can expect between 2 and 4 hours of moderate use, but this is an estimate that can vary significantly.

What warranty does it have and how can I return it if it doesn't work for me?

The battery has a 3-year warranty for private customers (1 year for professionals). You have 14 days to return it if you are not satisfied. Return shipping is at your expense, or you can request home collection for 8,90 € in Spain and Portugal, which will be deducted from the refund.
