CR2025 (2.5mm) and CR2016 (1.6mm) are thinner and will fit physically but may have loose contact. For reliable contact, use the correct CR2032 battery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: How long does a CR2032 battery last in an Arduino DS3231 RTC module?\u003c\/strong\u003e\u003cbr\u003eA: A CR2032 (225mAh) powering a DS3231 RTC in backup mode (typically 0.84μA) will last approximately 30 years theoretically. In practice, 5–10 years is typical due to self-discharge. The DS1307 draws more current (~500nA) and lasts approximately 5 years on a CR2032.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What is the pin spacing of this battery holder?\u003c\/strong\u003e\u003cbr\u003eA: The two through-hole pins are spaced to fit standard PCB footprints for CR2032 holders. The positive (+) terminal connects to the top spring contact, negative (−) to the bottom plate contact.
