Hi, I have a Gigabyte p34g v2 gaming laptop. When I use it on battery for browsing, it works fine (doesn't last too long though), but as soon as I launch a game, the laptop with shut down (just cut power). This happens no matter if the battery is on 100% or lower. When plugged in games work fine. I was wondering whether this is a battery issue, or something else, as if it is a battery issue, I would buy a new one, but just want to make sure that that's the problem, as a new battery is quite expensive, and I want to make sure it would fix my issue. Note that when plugged in, BatteryInfoView says the batteries voltage is 16,715 millivolts, but when the ac is disconnected, it immediately drops to around 15,278 millivolts.

My specs are:
CPU: I7 4700hq
GPU: GTX 860m
RAM: 16gb
Storage: 250gb ssd

Battery information (from BatteryInfoView):

It lasts for around 2:30 hours when browsing though, so I don't thing the battery percentage is wrong. Also note that battery health on BatteryInfoView is now suddenly showing 89.6%, which is weird. The problem still persists though. A new battery would cost $100, which is annoying.
