Frequently asked questions
How do I know if this P505M battery is compatible with my Dell laptop?
The safest way is to remove your current battery and check the part number printed on the label. If it matches P505M or any of the equivalents like GW240, RN873, or M911G, it is compatible. You can also check if your laptop model, such as Inspiron 1525 or 1545, appears in our list of compatible models.
My original battery is 10.8V and this one is 11.1V, is there any problem?
No, there is no problem. 10.8V and 11.1V voltages are fully compatible and interchangeable in 6-cell batteries like this one. The difference is minimal and is due to variations in cell chemistry. Your laptop's electronics will manage charging and discharging safely and efficiently.
Is it necessary to calibrate the battery the first time I use it?
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 normally until the battery is completely depleted and the device turns off. Finally, charge it back to 100% without interruptions. This process helps the operating system display the charge percentage accurately.
What warranty does it have and how can I return it if it's not the correct one?
We offer a 3-year warranty for private customers and 1 year for professionals. You have 14 days to return the product if it is not compatible or if you simply change your mind. 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.
