One of the failure modes of Lead-Acid batteries is that one or more cells can develop internal short circuit paths that result in varying amounts of self-discharge current. If your existing battery maintains its voltage above 12.5 Vdc for a week or more while sitting disconnected from anything else, it should be good.
The new battery might not be charged, or the battery terminals might be loose or have corrosion preventing the flow of electrical current. There could be burning smells . Usually accompanied by a massive spark after connecting the terminals backward, reversed polarity can be responsible for blowing fuses, damaging the alternator, causing burnt ...
