How does the button battery charge?
You can use three general 1.5V battery in series to charge it just keep the time very little.
Button battery is a one-time lithium-ion battery, can not be charged, otherwise it will cause an explosion. If you insist on charging, you can use the phone's charger to lead the positive and negative lines out to charge, must be a short time of contact, not a long charge, but also pay attention to safety.
You can use two copper on the 1st or 5th battery positive and negative poles fixed, and then the corresponding copper poles fixed to the two electrodes on the button battery. About 15 to 30 minutes or so, the electricity is good.
