For remotes that don’t draw a lot of current I use good carbon zinc batteries Everedy for AA and AAA. This is because they are less proned to leaking which is what has damage so many of my remotes. Alkalines leak, Duracell has been the worst for me. For 9V, I use Everedy Lithiums. I know you didn’t ask, but I’ve found Everedy AA lithiums to be the best for my HVAC thermostats and high current draw devices. Those lithium batteries last a long time and I haven’t been disappointed yet. On the other end, their AAA lithiums, have not impressed me.
Remote Maintenance
So here's a topic I haven't seen covered. How do you maintain your remotes? With all the gidgets, gadgets and gizmos we have, they all seem to have a remote. 9v, AAA, AA batteries in everything. Do you have a regular battery replacement plan, do you just check once in a while or do you wait until they stop working altogether and then replace batteries? And what about those leakers?
