Gonna replace the battery in my tablet this weekend. Done this sort of thing before, but not with this specific tablet (not quite a simple slot in a new battery job). Got all the tools. Shouldn't really be a problem but thought I'd let people know, just in case.
I'll use all my troopers tomorrow after tick-over and then later in the day I'll replace the battery. Should be back without interruption, and this gives me ~36 hrs in which to swap it over and get the tablet put back together.
Hopefully this will stop some of my crashes. *Fingers crossed*
