Quoted from daley:I think most people seem to have missed the OP's statement that you should use a remote battery holder. If your only concern is battery acid, and you are using a remote battery holder, then why change your batteries every year? Since even if the batteries do leak, it wont get on anything of importance.
Well you would still have to replace the remote battery holder?.......right.
Anyways. I still change them every year and have remote holders. Doesn't mean they won't start leaking in the a years time though. A few bucks for batteries is pretty cheap in this hobby.
