3V Ultra-Thin Coin Battery CR1025: Compact Size with Long-Lasting Stable Power

As electronic devices keep trending thinner, lighter and more miniaturized, traditional bulky button batteries can no longer match the design demands of slim portable gadgets. The CR1025 lithium manganese coin battery stands out as a premium 3V ultra-thin power solution. Boasting an ultra-compact wafer size and outstanding long-lasting discharge performance, this tiny battery delivers steady and durable power despite its minimal footprint.

Many users overlook this miniature battery due to its small appearance. However, its reliable 3V constant voltage output, ultra-low self-discharge rate and durable service life make it an ideal built-in power source for all kinds of slim low-power electronics. This article fully introduces the core strengths, key parameters, working performance and mainstream application scenarios of the 3V CR1025 ultra-thin coin battery.

1. Basic Core Specifications of CR1025 Battery

Designed exclusively for space-limited ultra-thin equipment, CR1025 features standardized dimensions and stable electrical parameters that fit most miniature low-power devices perfectly:

• Rated Voltage: 3.0V constant working voltage, matching most micro intelligent chips

• Physical Dimension: 10mm diameter × 2.5mm thickness, ultra-thin wafer-like body

• Nominal Capacity: 30mAh, optimized for long-term micro-current discharge

• Annual Self-Discharge Rate: ≤1%, extremely low power loss during standby and storage

• Shelf Life: Up to 5 years long storage life with over 90% remaining capacity

• Operating Temperature: -20℃ ~ +60℃, stable performance in daily indoor and mild outdoor environments

• Battery Type: Non-rechargeable primary lithium battery, leak-proof fully sealed structure

2. Two Core Advantages: Miniature Size & Long-Enduring Power

2.1 Ultra-Thin & Mini Compact Body

Different from conventional CR2025 and CR2032 large-diameter coin batteries, CR1025 adopts a smaller 10mm diameter while retaining 2.5mm ultra-thin thickness. Its tiny wafer shape occupies nearly no internal space inside slim electronics, helping manufacturers produce more lightweight, ultra-flat and portable products. It solves the core pain point that regular button batteries cannot be installed in ultra-narrow device cavities.

2.2 Long-Lasting Stable Power Supply

Small size never means short battery life. Equipped with mature lithium-manganese electrochemical formula, CR1025 maintains a flat 2.7V-3.0V stable voltage platform throughout most of its discharge cycle. There is no sudden voltage drop or power outage during daily use.

Thanks to ultra-low self-discharge technology, the battery hardly loses power when devices stay in sleep standby mode. For electronics working with long standby time and short intermittent pulse discharge, one single CR1025 battery can support continuous operation for 1 to 3 years without replacement, realizing truly durable power output.

3. Extra Practical Performance Highlights

• Excellent Pulse Discharge Response: Fast voltage recovery after instant current output, adapting to periodic signal wake-up of smart sensors and remote control modules

• Premium Leak-Proof Sealing Technology: Precision crimped shell and insulating gaskets prevent electrolyte leakage effectively, protecting delicate internal circuit boards of mini devices

• Consistent Voltage Output: Hardly affected by slight temperature changes, avoiding data errors or device crashes caused by unstable power supply

• Wide Compatibility: Interchangeable with BR1025, DL1025 and ECR1025, easy for global battery replacement and after-sales maintenance

4. Widely Applicable Mini Electronic Devices

Combining slim size and long-lasting power, CR1025 is widely applied in various portable ultra-thin electronics:

• Ultra-thin minimalist quartz watches and slim digital watches

• Lightweight wearable fitness devices: slim pedometers and motion tracking tags

• Outdoor portable gadgets: mini electronic compasses and keychain laser indicators

• Micro smart sensors, instrument clock backup power and miniature remote control modules

• Ultra-flat small smart home induction equipment and portable medical auxiliary devices

5. Important Usage Notes

1. CR1025 is a disposable lithium battery, charging is strictly prohibited to avoid bulging and leakage risks

2. Never replace it with 3.7V rechargeable LIR1025 battery, which will damage device circuits due to overvoltage

3. Avoid squeezing or piercing the ultra-thin battery shell to keep intact internal sealing structure

4. Store spare batteries in cool and dry places to extend overall shelf life

Conclusion

The 3V CR1025 ultra-thin coin battery breaks the stereotype that small batteries equal short service life. With an ultra-mini slim body, stable 3V voltage output and ultra-long standby endurance, it perfectly balances compact structure and durable power supply.

For all ultra-thin, space-limited miniature electronic devices that pursue lightweight design and long battery life, CR1025 is a reliable, cost-effective and stable dedicated power supply solution — small in appearance, but powerful and persistent in performance.
