How Often Should I Charge My Motorcycle, ATV or Boat Battery?

Any type of lead acid battery should always be left in a fully charged condition. Having done that, you should either charge your battery every 30 days or so, or consider getting a smart charger to maintain your battery all the time. These new ‘smart’ chargers will hold the voltage at its prime voltage, while reducing the current to almost nil, thus preventing overcharge even when left on for months at a time. A battery will self discharge over time, even while not in use or connected to anything, thus the benefit of constant maintenance charger.
