While they share the same diameter, the CR2025 is thinner and has lower capacity. Ensure your battery holder provides sufficient contact pressure for the thinner cell.
Non-Rechargeable Primary Batteries Component Intelligence
Engineering-grade primary cells for RTC, memory backup, and low-power IoT.
What are Non-Rechargeable Primary Batteries components?
Primary batteries are designed for single-use, high-energy-density applications where recharging is impractical. Selection hinges on discharge rate, operating temperature, and self-discharge characteristics, especially for RTC and memory retention circuits.
How to Choose Non-Rechargeable Primary Batteries Components
Selecting the right primary cell requires balancing energy density against the specific discharge profile of your load.
Chemistry Selection
Choose Lithium (Li-MnO2) for high energy density and wide temperature ranges, or Alkaline for cost-sensitive, moderate-drain applications.
Discharge Profile
Analyze whether your application requires continuous low-drain (e.g., RTC) or periodic high-pulse currents (e.g., wireless transmission).
Self-Discharge Rate
For long-life designs, prioritize chemistries with low self-discharge to ensure the battery retains capacity over years of shelf life.
Physical Constraints
Verify PCB footprint and mounting style, such as coin cell holders versus tabbed or leaded configurations for direct soldering.
Operating Environment
Account for thermal extremes; standard batteries may fail or leak in harsh industrial or outdoor environments.
