Got a new battery for my razer blade 13 as it was old and wouldn't hold a charge for more than a few hours. I replaced the battery and the laptop turned on, so I plugged it in to calibrate. It won't charge above 94% and now shuts off when disconnected from ac. I got a second battery as I thought the first one was defective and it did the same thing. If I plug in the old battery, it works fine and has no issues running without being plugged into ac. Could this be two defective batteries? The model number (RC30-0916) is the same and the website ordered from (ifixit) claims to work with the razer blade 13.
