With the continuous miniaturization and low-power upgrade of consumer electronics, smart home gadgets, and industrial sensing equipment, miniature coin batteries have become an indispensable core power component. Among numerous button cell models, the CR1130 3V lithium manganese coin battery stands out for its ultra-stable voltage output, ultra-low self-discharge rate, long service life and compact body structure. It has gradually become the preferred standard power source for countless slim, low-current, and long-standby miniature electronic devices. This article comprehensively introduces its core performance, structural advantages, application scenarios and product value, helping users and engineers complete efficient and reliable battery selection.
The CR1130 is a non-rechargeable primary lithium manganese dioxide coin cell that complies with international universal industry standards. Its model naming clearly defines its size and chemical system: "CR" represents 3V lithium manganese chemistry, "11" refers to 11.0mm diameter, and "30" stands for 3.0mm thickness. Its compact and ultra-thin size perfectly adapts to the slim structural design of modern miniature electronic products.
The core standard parameters are listed below:
Nominal Voltage: 3.0V (stable flat discharge voltage)
Rated Capacity: 40mAh
Physical Dimension: 11.0mm × 3.0mm
Working Temperature Range: -20℃ to 60℃
Annual Self-Discharge Rate: ≤1%
Ultra-Long Shelf Life: Up to 10 years of room-temperature sealed storage
Optimal Discharge Mode: Long-term micro-current steady discharge
Different from ordinary alkaline batteries that suffer from continuous voltage attenuation during operation, the CR1130 maintains a nearly flat discharge curve throughout most of its working cycle. It stably outputs 2.9V–3.0V voltage without sudden voltage drop or power fluctuation. This ultra-stable power supply effectively avoids abnormal shutdown, signal instability and timing deviation of precision miniature devices, ensuring consistent and reliable equipment operation.
Equipped with high-purity lithium manganese chemical system and optimized internal electrode structure, the CR1130 delivers high energy density in a tiny size. For low-power standby devices such as electronic clocks, car key fobs and motherboard backup modules, it can provide continuous power support for 1 to 3 years of daily use. For static industrial standby equipment, its service life can even reach 5–8 years, greatly reducing frequent battery replacement costs.
Thanks to the high-tightness laser welding sealing process and stable electrolyte formula, the CR1130 achieves an extremely low self-discharge rate. It retains more than 80% of its original capacity after 10 years of sealed storage, far exceeding the storage performance of ordinary alkaline and silver oxide batteries. It is very suitable for product inventory backup, long-term equipment standby and disposable electronic devices with long shelf-life requirements.
The CR1130 performs well in both low-temperature cold environments and high-temperature indoor scenes. It can work stably at -20℃ low temperature without power attenuation, and maintains structural stability at up to 60℃ high temperature. It adapts to complex temperature changes in vehicle interiors, outdoor monitoring and household environments, with strong environmental tolerance and low failure rate.
Relying on its stable performance and miniaturized advantages, CR1130 is widely recognized as a standard power source for multiple industries, covering consumer electronics, automotive accessories, industrial intelligent equipment and smart home fields.
It is widely used in ultra-thin electronic alarm clocks, kitchen timers, LED cosmetic mirrors, portable mini flashlights, small electronic toys and daily miniature gadgets. Its long-lasting and stable performance ensures daily equipment runs smoothly for years.
Slim car key fobs, tire pressure monitoring sensors (TPMS), vehicle-mounted wireless reminder devices and other automotive accessories all adopt CR1130 as the core power supply. Its excellent temperature resistance perfectly adapts to complex vehicle working environments.
As CMOS backup power for industrial control motherboards, low-power RFID tags, miniature temperature and pressure sensors, and portable precision detection instruments, CR1130 provides stable standby power to prevent data loss and ensure long-term unattended operation of industrial equipment.
To meet the needs of mass electronic production, CR1130 can be customized with positive and negative nickel tabs for direct PCB welding, replacing traditional battery holders. This solution saves product internal space, optimizes structural stability, and improves the consistency and durability of finished electronic products.
For daily replacement and bulk procurement, CR1130 has multiple fully interchangeable equivalent models, including DL1130, ECR1130 and KCR1130, with identical size, voltage and discharge performance. For ultra-low power static equipment, BR1130 can be used as a backup alternative, though it is not recommended for pulse signal devices such as remote controls.
It is worth noting that look-alike models such as CR1116 and CR1125 have different thicknesses and cannot be replaced blindly, so users must confirm the exact model during selection to avoid poor contact and equipment failure.
The CR1130 3V lithium manganese coin battery integrates stable voltage output, ultra-long service life, low self-discharge and strong environmental adaptability. Its miniaturized size and reliable performance make it an ideal preferred power source for modern low-power miniature electronic equipment. Whether for daily consumer product replacement or industrial batch supporting applications, CR1130 can deliver stable, cost-effective and long-lasting power solutions, fully meeting the high-quality power supply demands of miniature electronic devices.
