Battery Voltage 0mV on getvar, while it is full

sprint HTC one M8, in a try to unlock it, SIM unlock helper app locked my device and after failing to perform the regular factory reset I had to use the recovery to wipe all data including system, as deleting user data only using fastboot failed. As I am trying to restore a stock rom after relocking bootloader I keep getting a less than 30% battery level while it is full.. please assist me on what to do.. the below info might help you!
