CR2025 3V Lithium Coin Cell Battery

The CR2025 is one of the most widely used coin cell sizes, powering everything from small remote controls and keyless entry fobs to backup clock circuits and compact sensor modules that can't fit a bulkier AA or AAA cell. Its lithium chemistry gives it a notably long shelf life compared to older alkaline coin cells, so it holds its charge reliably even in devices that only draw power occasionally, such as a real-time clock module's backup supply. This generic version covers everyday replacement needs where the specific battery brand doesn't matter as much as simply having the right size and voltage on hand.
