Can you buy a battery pack for this model or one that is compatable as the batteries last bugger all?

Your camera takes a proprietary NH-10 battery, but if you search online it's widely available and not particularly expensive even if you buy the Fuji-branded version over the slightly cheaper Uniross model.

Note that the link to a UK supplier is for reference only, you will find other suppliers both in the UK (where I'm based) and in other countries by just entering "FujiFilm NH-10" into your search engine.

Please take a moment to rate my answer, and I hope that your "bugger all" battery life days are soon behind you!
