Frequently asked questions
How do I know if this WK381V battery is compatible with my Dell laptop?
The safest way is to remove your current battery and check the printed part number. If it matches WK381V, GW240, RN873, or any other from the compatible list, it will work. You can also verify if your laptop model, such as 'Inspiron 1525', is on our list of compatible models.
Do I need to calibrate the new battery upon receipt?
Yes, it is highly recommended to optimize its performance and the accuracy of the charge indicator. To do this, charge the battery to 100%, then use it until the laptop turns off due to low battery. Finally, recharge it to 100% uninterruptedly. This initial cycle helps calibrate the cells.
How many hours of autonomy will this battery provide?
Autonomy depends on laptop usage, screen brightness, and running applications. With 4400 mAh, you can expect a duration of between 2 and 4 hours in standard office use, a performance similar to what the original battery offered when new.
