Frequently asked questions

A typical full charge cycle lasts between 3 and 4 hours. If it takes longer, consider testing with a different power adapter.

Yes, but be aware that printing consumes power and may extend the total charging time significantly.

If the battery fails to hold a charge for more than 1-2 hours of usage, it is likely at the end of its functional life.
