Power Glory’s CR-PH coin cell batteries are engineered specifically for modern smart car keys requiring high-pulse discharge and extended lifespan. Featuring a 20% higher peak current and 10–20% greater capacity than standard models, the CR-PH series powers advanced keyless entry, push-button start, and UWB digital key systems without voltage drops. Built with precise sizing, ultra-low self-discharge (<2%/year), and wide operating temperatures (-20°C to +70°C), it delivers long-lasting, automotive-grade reliability.

Car keys generally use CR2025 and CR2032 lithium batteries. You can buy them based on the old battery model. The cr2032 button battery provided by Power Glory always provides strong power for your car key every day.
