CR2025 और CR2032 सबसे common coin cell batteries हैं। Car key fobs, watches, calculators, small electronics में use। Similar दिखती हैं, लेकिन हमेशा interchangeable नहीं।
Basic Specs
दोनों 3 volts, lithium chemistry, 20mm diameter। CR2025: 2.5mm thick, 150-170 mAh। CR2032: 3.2mm thick, 220-240 mAh। CR2032 roughly 30-40% longer lasting।
Size Fit
Same diameter (20mm)। 0.7mm thickness difference matters in tight compartments। Device specifically CR2025 designed तो CR2032 fit नहीं होगी। Loose connection problems vice versa।
Common Uses
CR2032: CMOS motherboard battery, car key fobs, glucose monitors, fitness trackers। CR2025: slim watches, certain remotes, compact medical devices। Both low-drain applications।
Interchangeable?
Electrically compatible (same voltage)। Physical fit depends on compartment space। Always check device manual। Never force wrong size, contacts damage हो सकते हैं।
Shelf Life
Both excellent: 8-10 years unopened। Low self-discharge rate। Room temperature dry storage ideal। Good for emergency kits।
Brand Quality
Energizer, Duracell, Panasonic, Sony = consistent quality। No-name brands often overstate capacity। Reputable brand worthwhile especially for critical applications।
Safety
Serious child ingestion hazard = immediate medical emergency। Always store away from children। Dispose at proper recycling centers, not regular trash।
