Yeah, right....

If there's one lesson I've learned from all stuff I've wrecked over the years, there's usually always someone who has done it before, so always check the forum before trying something that's new to you, to avoid this kind of situations.

If the store, you bought the battery from, is half decent, 'they' should give you a refund or a new battery to compensate for their incompetence.
