Batteries losing charge while in storage
My four six volt AGM batteries are losing there charge while the trailer is parked in storage. I disconnected all the wires from the positive terminal but still find them slowly discharging. In a se...

I should have mentioned, be sure you get one that measures DC current. Less expensive ones may only measure AC current.
Sears sells a decent DC clamp meter. I wouldn't buy one just for this job, unless you are a tech type and want one for the future. Here's what I'd do: many meters have a 10 amp input. It's usually separate from the normal scale. Buy or borrow one, preferably one with a fuse. Unplug all the 12 volt fuses in your panel. Connect the 10A meter in line with the battery - between the battery and the battery cable. Then slowly replace fuses until you see some current showing. The drain is on that fuse. If you get all the fuses back in and see no current, then it's not a drain problem and you have to look at the battery. The problem should have shown in the initial test of just watching the battery voltages with the batteries disconnected.
