AI Overview
The code
Honeywell 10012/1/2 refers to a specific Honeywell Central Processing Unit (CPU) module, not a battery for household devices; it's for their industrial automation (FSC) systems, needing 5VDC/24VDC power, and is often listed on sites like eBay as industrial hardware. If you're looking for batteries for a Honeywell thermostat, you likely need common household batteries like AA or AAA (check your specific model), while alarm systems use sealed lead-acid batteries (like UC12102).
