Frequently asked questions
Is this battery compatible with my Sony VAIO?
This battery is specifically designed for Sony VAIO PCG-4121GM and PCG-41414M models. To ensure compatibility, check that your laptop model matches this list. If your original battery has a different part number but your laptop is one of the indicated models, this battery should work.
My original battery is 10.8V and this one is 11.1V, is that a problem?
No, it's not a problem. 10.8V and 11.1V voltages are fully compatible in Li-Ion batteries. Manufacturers use cells with slightly different voltages (3.6V or 3.7V), but the laptop's circuit is designed to handle this small difference without any risk to the equipment.
Do I need to calibrate the new battery?
Yes, for optimal performance, 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. Finally, charge it back to 100% without interruptions. This helps the system recognize the new battery's actual capacity.
What is the warranty and how do returns work?
The battery has a 3-year warranty for private customers and 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.
How long does the order take to arrive?
Shipping is prepared from our warehouse in Spain in 0-1 business days. Delivery in Spain and Portugal takes 24-48 business hours. For other EU destinations, the timeframe may vary between 2 and 5 business days.
