Frequently asked questions
How do I know if this 718677-421 battery is compatible with my laptop?
The safest way is to remove the current battery from your laptop and check the part number (P/N) printed on the label. If it matches 718677-421, compatibility is guaranteed. Also, verify that the voltage (10.8V/11.1V) and physical shape match your original battery.
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 shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the battery's actual capacity and optimizes its lifespan.
What warranty does this battery have and what happens if it doesn't work or fit?
We offer 3 years 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 shipping on your own or request a home pickup for 8,90 € in Spain and Portugal, which will be deducted from the refund.
How long does this battery's charge last approximately?
Autonomy depends on the laptop model, its power configuration, and its usage. With 4400 mAh, this battery aims to match the duration of the original battery when it was new. Generally, you can expect between 2 and 4 hours of moderate use, but this value is indicative.
