Frequently asked questions

How do I find the right battery for my laptop?
The exact laptop model and the code of the original battery, printed on its label, decide. The replacement battery's name lists compatible models and the original code. If unsure, send us the laptop model and the battery label and we will check.
What do mAh and Wh mean?
Wh (watt-hours) states the battery's energy and is the best measure of run time; mAh (milliampere-hours) is meaningful only at the same voltage. A battery with more Wh than the original lasts longer, but must have the same voltage and shape.
What is the warranty on a replacement battery?
Replacement batteries carry the statutory 24-month consumer warranty. A battery is a consumable, gradual capacity loss through normal use is not a defect. For laptops with an internal battery we can fit it at pickup in Písek.
