Invalid battery for LG V10 phone.
This battery is labeled and marketed as though it is a legitimate replacement for the original LG battery. Unfortunately, within about 30 seconds of inserting it into my phone, an error message declaring it an "invalid battery" is displayed and the phone powers down. I looked for solutions to this issue online, and although there are some suggestions, none worked for me. I am not willing to do a hard factory reset simply to see if that might work. I decided to return the battery and the seller will not even pay for shipping for this item. Very disappointing purchase. I won't be ordering from this seller again.
