Starting with the obvious, have you taken it for a long drive yet? if you have purchased it from a garage, it may have been sitting round for a bit.
It could be the alternator too, presumably the previous owner/ garage may have fitted to battery to get rid of a battery warning.
Is it starting OK, unusual to have the warning and starting ok, check the ground cable to the battery, a few people have complained theirs was not connected up to the chassis correctly (if it is starting OK, I would check all the connections first), there are a couple of threads on this.
