Can Fast Charging Damage Your Battery. Leaving it alone damages the battery. Although manufacturers avoid damage to the battery by using intelligent charging electronics or tricks such as splitting the battery in.
Answer 1 of 29. Id go into more detail about this but most people just want a number they can use. All charging damages the battery.
The question is by how much.
When the battery is fully charged the power supply disconnects the charging circuit so that does not charge the loaded battery anymore. All 6 bays default to 05 but the 4 inner bays can be cranked up with the phone app to 10 if not charging more than 4 batteries and the 2 outer bays can be cranked up to 20 if only charging those 2 bays. However this is not normally a problem if you use the original phone charger. But as with so many things about batteries there is no hard threshold between a charge rate that causes no damage and one that does.
