An ordinary alkaline battery in normal use in your home is unlikely to catch fire spontaneously. However, if a battery is kept in a device for too long, it may leak the contents and this could potentially start a fire. You might also short circuit a loose battery to cause a fire. There are some safety concerns when it comes to batteries and fire.
Without the stored potential energy, the battery has a difficult time generating the heat required to ignite the electrolyte, even when there''s a short-circuit. Puncturing a less than 25% charged battery might generate sparks and smoke, and the battery could get really hot, but it''s unlikely to catch on fire and enter thermal runaway mode.
