A 12v battery can sit unused for about 6 months before it requires a recharge, provided it's kept under ideal conditions (cool and dry). After 6 months, the battery may start to lose its charge due to self-discharge. To prolong its lifespan and maintain its health, it's recommended to charge the battery every 6 months. Furthermore, storing the battery in a cool, dry place and disconnecting it from any power drains can significantly help in preserving its charge over periods of inactivity.
