Frequently asked questions
How can I be sure that this 312-0822 battery is compatible with my Dell Latitude?
The most reliable way is to compare the part number of your original battery with the list of compatibles. Disassemble your current battery and look for codes like 312-0822, U817P, W8H5Y, etc. If it matches, it is the correct one. You can also check if your laptop model, such as Latitude E4300 or E4320, is on the list of compatible models.
Is it necessary to calibrate the new battery the first time I use it?
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 equipment turns off. Finally, recharge it to 100% without interruptions. This process helps the operating system display the charge level accurately.
