Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Are you asking how to CHARGE or CHANGE the battery?To charge, you remove it and connect it to an auxiliary charger device. Do you need help with finding a replacement battery or charger?
Then you will have to buy one. I cannot control what equipment you do or do not own.
You either leave it on the camera and plug in an auxiliary power cord for on board charging, or you purchase an external charger. One or the other is necessary, there is no other possible way of charging it. If you need help finding a charger to purchase, I can help you with that.
