Frequently asked questions
My laptop is an Acer Nitro 5 AN515-58, is this the correct battery?
Yes, this AP21D8M battery is compatible with the Acer Nitro 5 AN515-58 model. For complete certainty, we recommend turning off your device, disassembling your current battery, and confirming that the part number printed on it is AP21D8M or KT.0040G.015.
My original battery says KT.0040G.015, is this AP21D8M compatible?
Yes, they are fully compatible. Manufacturers often use several part numbers for the same part. AP21D8M and KT.0040G.015 refer to the same battery, and you can use this as a direct replacement without any issues.
Is it necessary to calibrate the new battery the first time it is used?
We recommend an initial calibration cycle to optimize the accuracy of the charge indicator. Charge the battery to 100%, let it rest for an hour, then use the laptop until it shuts down due to low battery (or reaches 5-7%). Finally, charge it back to 100% without interruptions.
What warranty does it have and what do I do if it doesn't work or doesn't fit?
We offer a 3-year warranty for private customers and 1 year for professionals. If the battery does not work or is not compatible, you have 14 days to return it. You can manage the return shipping yourself or request a home collection for 8.90 € in Spain and Portugal.
