Frequently asked questions
How do I know if this RU591 battery is compatible with my Dell laptop?
To ensure compatibility, check the part number on your original battery. If it matches RU591 or any of the equivalents such as GW240, RN873, or M911G, it will work. You can also check if your laptop model, such as Inspiron 1525 or 1545, is on our compatibility list. If in doubt, contact us with the exact model of your equipment.
Is it necessary to calibrate the new battery the first time?
Yes, it is 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 turns off. Finally, recharge it to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery.
What autonomy can I expect from this 4400mAh battery?
Autonomy depends on laptop usage (screen brightness, running programs, connectivity). With 4400mAh, this battery aims to offer a duration similar to the original when it was new. Light office use and web browsing will provide greater autonomy than video playback or gaming.
What warranty does it have and what do I do if it doesn't work or fit?
The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it does not fit your laptop or does not work correctly, 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.
