How to charge your new Acer laptop battery?
For initial use, it is always advisable to discharge the Acer laptop battery to 3% only and then fully charge it (approx 12 hrs). Do NOT let the battery discharge to 0% initially, as it makes the battery prone to damage/short battery life/not holding the charge issues. Battery once used must be recharged within 2 days without fail with above 50% before using it else it will cause damage/short battery life issues/not holding the charge issues. Acer battery needs a cycle of discharging to 3% and then fully charging twice a week.
