I've just realized that my DiMAGE X1 won't charge when it's plugged into my cradle dock that came with my camera. When plugged in, the charge light illuminates for about a minute and then goes out, but when I turn on my camera, the battery indicator only shows 1/3 power. Is the problem likely with my cradle or my battery? Also, when I pulled out my battery, I noticed that it's a little bloated. I imagine that when the battery was new, the casing was completely firm, but now it's a little squishy on both sides. Is that going to be an issue?
