If you have time and energy today, please check the batteries in your remotes, electronics, flashlights (especially your flashlights!) and whatnot!
If they're not being used, remove them. If they're dead, remove them. If they're corroded, remove them and carefully clean the battery compartment and contacts before leaving empty or replacing.
Disposal varies by location (local recycling center takes mine).
Brought to you by me finding a lot of bad/dead batteries this weekend while checking things and the low-battery light on my autodark welding helmet.
