Frequently asked questions
My laptop is a Dell Inspiron 1545, is this the correct battery?
Yes, this battery with part number 0WK381 is fully compatible with the Dell Inspiron 1545. To be 100% sure, we recommend removing your current battery and checking that the part number printed on it matches 0WK381 or one of the listed equivalents, such as Gw240, Rn873, or M911g.
Do I need to calibrate the new battery when installing it?
Yes, it is highly recommended. To calibrate it, install the battery and charge it to 100% without interruptions. Then, use the laptop until the battery is completely depleted and the device turns off. Finally, charge it back to 100% without using it. This process helps the system recognize the battery's real capacity and optimizes its performance.
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 customers and 1 year for professionals. If upon receiving it you find that 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.
How long does it take for the order to arrive at my workshop in Barcelona?
Orders to peninsular Spain, such as Barcelona, are delivered within 24 to 48 business hours. If you place the order before 16:00 on a business day, it is prepared and shipped the same day, so you could receive it the next day.
My original battery has a voltage of 10.8V, can I use this 11.1V one?
Yes, without any problem. 10.8V and 11.1V voltages are equivalent in 3 and 6-cell Li-Ion batteries. The difference is minimal and is due to the way the nominal voltage of the cells is measured. Your laptop will work perfectly with this 11.1V battery.
