Is there anything that needs to be done if I leave the battery disconnected for a month or two? Does the alarm need to be reprogrammed? I'm more comfortable leaving the battery tender on the work bench for a month or two with other batteries that need to be maintained than in the trunk of the car.

As long as you make sure the immobilizer and alarm are not set/on at the time you remove the battery cables, you will have no need to reprogram the alarm after removing the battery for long periods of time.

What about the alarm's backup battery, though? I can't imagine this being good for that.

Probably not but I do not know what type of battery they used to know for sure. It is generally not a good idea to kill a battery and leave a draw on it with some electronic gizmo.

The back up battery is in the siren and its only use is to sound the siren if the power is removed from the alarm module while it is armed. In other words, there is no draw from the battery under any other circumstances.

Why? I've been hooking up Battery MINDers on my cars during winter storage for many years now, and never had a problem. That's what the maintainers are made for, and leaving the battery in the car/boot is no problem at all. :shrug:

Maybe because he has multiple batteries which can all be connected to the Battery Minder together, in parallel :shrug:.

You can also get a Battery MINDer (or Battery Tender) that has multiple connections so that they can maintain multiple batteries. I wouldn't think that connecting them in parrallel would be a good idea (different charging/discharging rates and all that...)... :shrug:

Actually, with the 12117 you can connect up to four batteries.

Someone else guessed it: One timer, multiple batteries. Between boat batteries and car batteries, my workbench used to look like the battery rack at Pep Boys in the winter.

Just being creative here because it's fun, but if the conditions were right, you could leave the battery in the Lotus and still connect the others up in parallel. They would either have to be close enough, or the jumping cables would have to be large enough to diminish the voltage drop. Only you know your logistical conditions, but there are many ways to solve a problem ;).
