CR2025 vs CR2032
A CR2025 is 0.7 mm thinner than a CR2032. If the holder is designed for CR2032 (3.2 mm), the thinner CR2025 can wobble or lose contact; devices stamped CR2025 (2.5 mm slot) usually accept a CR2032 only with risk. Match the printed size.
Wholesale & Custom Supply

FAQ
What is a CR2025 battery?
A 20 mm diameter, 2.5 mm thick 3V lithium coin cell, about 165 mAh typical capacity.
Can I replace a CR2032 with a CR2025?
Only if the slot fits — a CR2025 is 0.7 mm thinner and may not seat properly in a CR2032 holder.
Is CR2025 the same as ECR2025?
Yes — ECR2025, 5003LC and DL2025 are equivalent designations.
