Carmen,
Im installin a battery maintainer on mine just to make the PA winter storage less of a pain I have one on my 67 Triumph motorcycle and my bass boat and love them.
If you are only gonna run it a few times/month it sure wouldnt hurt to have one on your ride.
Put it to bed plug it in an forget it.
at least ya know the battery will have a full charge the DAY you wanna roll.
just my thoughts.
Tim
