XPS 9570 battery upgrade from 56Wh to 97Wh

Hi guys,

So I bought a Dell 6GTPY 97Wh battery to replace the smaller one that came from factory. Thing is computer completely powers off when in 80%. I bought a new one, still behave weird... sometimes it shuts at 10%, yesterday at 60%. There's no pattern. Is there any configuration or BIOS set up I should do after I've switched. By the way, the 56Wh works fine and doesn't shut my computer down, it just works normal. The other two 97Wh are behaving weird, I cannot unplug the computer with low battery (around 40% for example) without making the computer go off.

Thanks in advance! 

Kevin.
