Just spoke to blokey from datatool, he works on the tech support so should know what he's on about!
He says it won't be a problem at all if the internal battery drains... just plug it all back in when ready and the alarm will come back on in service mode when the bike battery is reconnected, and the alarm battery will charge itself up again. The zappers won't even need to be re-aligned.
steve, you also have a u2u with some more info
