The new lesson amplifier should be recharged or recharged
First run out of electricity, and then charge, the first charge for a longer time, at least 12 hours.
It should be recharged first.Charging notes are as follows:1., buy a computer first thing is to use the battery in the notebook clean, don't see the battery point is not much, began charging, this is wrong. The output power of the notebook belt is to protect the battery, so it must be exhausted before it can be charged.2., the first three charging time between 12 hours to 14 hours, each full power to be used up, in the second charging.3., the first three charging is very important, although now that the battery has no memory function, you can use it casually, but the battery is a battery after all, a good start can determine your battery life in the future. Whether it's a previous battery or a current battery, you need to pay attention to that.
Use up again, look at the instructions, must be full of charge, activation of the battery, or it will affect its service life. I hope I can help you
