what do your guys think of trickle chargers, I have a couple cars that are sitting and was thinking about purchasing trickle chargers to keep the batteries from going dead?
Are you using an old-style "dumb" trickle charger? Generally the situation you describe is why they're not a good idea. The modern, microprocessor controlled ones should not do this, as they stop the trickle charge once the battery is full and only restart it after the battery drops below a certain threshold.Used one of the battery tenders in the boat while it sat between uses, and found that the slight but continual charging by the tender will slowly drive the water out of the battery, thus ruining the battery. If you use one of these things, you have to keep an eye on the fluid level in the battery.
