Frequently asked questions
How do I know if this 312-0763 battery is compatible with my Dell laptop?
To ensure compatibility, check the part number on your original battery. If it matches 312-0763 or any of the equivalents like GW240, RN873, or M911G, it is the correct one. You can also check if your laptop model, such as Inspiron 1525 or 1545, is on our list of compatible models. The voltage should be similar (11.1V or 10.8V are compatible).
Is it necessary to calibrate the new battery the first time?
Yes, an initial calibration cycle is recommended. Charge the battery to 100%, let it rest for an hour, then use it until the laptop shuts down due to low battery (approx. 5%). Finally, charge it back to 100% without interruptions. This helps the system recognize the actual capacity and optimizes its long-term performance.
What autonomy can I expect from this 4400mAh battery?
Autonomy depends on laptop usage (screen brightness, running programs, etc.) and its energy consumption. A new 4400 mAh (49 Wh) battery should provide between 2 and 4 hours of moderate use, restoring the original mobility of your device.
What warranty does it have and how does the return work if it's not compatible?
The battery has a 3-year warranty for private users (1 year for professionals). If it is not compatible, you have 14 days to return it. You can manage the return shipping on your own or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
