I thought you might be on KitKat.. KK doesn't use image files for the battery icon unlike every previous version of Android. The battery icon is rendered by code.
To use the battery icons in TMA, you'll need to first mod your SystemUI.apk so it uses image files again.

Is there any tutorial for that? Or could you at least give me a short how-to? Or a modifyed SustemUI.apk?
