Frequently asked questions
How do I know if this WD549AA battery is compatible with my HP laptop?
The safest way is to check the part number of your original battery. If the label says 'WD549AA' or an equivalent part number, this battery is correct. You can also compare the voltage (V) and the physical shape of the battery with our product images to ensure a perfect fit.
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% without interruptions, then use it until the laptop shuts down due to low battery (approximately at 5%). Finally, charge it back to 100% without using the device. This process helps the system recognize the battery's actual capacity and optimizes its lifespan.
How many hours of battery life can I expect from this 4400 mAh battery?
Battery life depends on your laptop's power consumption (processor usage, screen brightness, etc.). A 4400 mAh battery like this should provide between 2 and 4 hours of moderate use, similar to the original battery's life when it was new. This is an estimate, not a guaranteed value.
What warranty does it have and what do I do if it doesn't work or doesn't fit my laptop?
We offer a 3-year warranty for private customers and 1 year for professionals. If the battery is not compatible or has any defect, 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.
