FWIW, I have remotes on all my pins-17 at the moment, and change them religiously every 1st week of the new year. The remotes are all located right by the plumb-bob tilt so they're easy to get to. To date, no leakage, but just to ensure that it never happens, I'm swapping all batteries out this year to lithium. You can get multi-packs of these online cheap. I know that lithiums would last much longer than a year but I'll still swap out after 1 year and just use them up in some other non-essential device...
