I see the problems of both sides, because, with an icon
would be hard to change it depending on plasma theme
limited only for some sizes

however:
it is absolutely true that a svg rendered at a random size can look really bad 
when is not aligned at the pixel grid or it too detailed (or not enough) for 
the rendered size (in the end this is why true type fonts have that scary 
hinting language)

so what i propose is the following:
use the svg for the battery as now, -but-
if we are rendering at a certain size, and the element in the svg we want to 
render is "battery" search another one with the proper prefix, for instance 
"22-battery" before. it can be a svg, an embedded pixmap whatever (we should 
really understand what is the more efficient between the two probably)
if is found paint that, otherwise paint  the fallback general one.

we will need probably just a couple of really used sizes, probably 22x22 that 
is the (still fixed) systray icon size and a slightly larger, like 32x32?

for big "in the desktop" sizes an one and only free scaling svg probably would 
be just fine
