Quote: Never used one and my battery's last 8 to 9 years. I usually just toss the charger on them twice during winter storage for 3 or so hours, and right before I start it in early April. My garage stays at around 52 degrees over winter.
Works for me also.
Same here.... If you do use a trickle charger, watch your water level
Me three, I just charge them a few times a year when they are not being used.
Feels good doing it and you can say "I worked on the car today"
