FAQs
Q: How to charge a new battery for MSI BTY-L77 for the first time use?
A: New MSI BTY-L77 battery pack is normally shipped in its partially charged condition. Please cycle your new BTY-L77 battery pack by fully charge and discharge it for 3-5 times to allow it to reach its maximum rated capacity before use. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging).
New batteries are hard for your device to charge; they have never been fully charged and are therefore "unformed". Sometimes your device's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should begin again. This may happen several times during your first battery charge. Don't worry; it's perfectly normal.
Q: The MSI BTY-L77 battery has been installed several times, but device can't boot up?
A: Carefully check if interfaces of the device and the battery are correctly connected. If the cause of loose contact is ruled out, please contact the after-sales customer service to ensure that the battery part number and device model are matched.
