I haven't used it for one or two years. Electricity is still there. But in this case, how long is the battery life? Model: winner DA-1210G portable microphoneCome to think of it, it was bought last December. It has not been used for weeks.
Generally speaking, the normal life of a good battery is repeated charge and discharge 200-250 times, converted to know.
The quality of the winning megaphone is still very good. I've been using it all the time. It worked really well.
Lithium battery normal service life is about 3 years, and quite repeated charging and discharging 500 times, if not used for a long time, it is recommended to full storage before the electricity, to take out the charge, so as not to damage the battery.
