Cheers. It looks like the problem might be simpler than that. It just so happens that my battery cover has one of the three plastic notches that seat the cover in has broken off - Which happens to be the one at the side of the contacts. Luckily, I've found the broken piece, so I should just be able to glue it back together, and that should be okayThis probablem usually occurs when the battery isn't making full contact with the pins.
Reseat the battery: just take it out and put it back in. Sometimes a piece of folded tissue paper between the battery and the cover helps.
Neither - it's to do with the battery/battery caseIs that with the charger or over USB? If it's over USB, then from my experience that's pretty normal.
