The seller sold me what they claimed was a brand new OEM LG battery. When charged it only lasted 30 minutes. It drops 3 bars in that time. That is WITHOUT using it. I mostly only use my phone for texting. There was NO mfg. or expiration date on the battery so who knows how old it actually is. Real batteries have a date on them. It wasn't even in the original packaging. Could be a faux LG battery. Total junk. Seems to be scores of negative reviews about them selling defective batteries. 166 negative reviews is pretty bad and not a coincidence. They had the gall to ask me to remove my negative review of them. Amazon should be contacted just how many buyers received defective batteries. They should not be allowed to sell anything on Amazon. What a sham.
