As one of the most common 3V lithium manganese coin batteries in the miniature power supply industry, the CR1130 coin battery is widely adopted in low-power portable electronic devices thanks to its ultra-small size, stable voltage output and long shelf life. However, most users lack systematic cognition of its core parameters, performance advantages, interchangeable models and usage taboos. This article will conduct a full-dimensional and detailed interpretation of the CR1130 battery to help engineers, procurement personnel and ordinary consumers complete accurate battery selection, replacement and daily maintenance.
The model naming of coin batteries follows unified international industry standards. The "CR" stands for lithium manganese dioxide primary battery with a nominal voltage of 3.0V; the number "11" refers to the battery diameter of 11.0mm, and "30" represents the battery thickness of 3.0mm. Below is the complete official parameter table of CR1130 battery:

Key Reminder: CR1130 is a disposable non-rechargeable battery. Any attempt to charge it will cause internal short circuit, battery bulging or even safety hazards such as liquid leakage.
Compared with silver oxide batteries and alkaline coin batteries of the same size, CR1130 lithium manganese coin batteries have irreplaceable performance advantages, which are summarized into four core characteristics:
Different from alkaline batteries whose voltage drops rapidly during use, CR1130 can maintain a stable 3.0V voltage output in the whole discharge cycle. It will not cause device failure or signal interruption due to voltage attenuation, which is very suitable for precision electronic components that require strict voltage stability.
The internal sealed structure and stable chemical system make its annual self-discharge rate less than 1%. After 10 years of sealed storage at normal temperature, the remaining power can still reach more than 80%. It perfectly meets the long-term standby power demand of equipment that is not frequently replaced with batteries.
It can work normally in both low-temperature cold environments (-20℃) and high-temperature indoor environments (+60℃). It has better low-temperature performance than alkaline coin batteries, so it can be used for outdoor miniature sensing equipment and automotive on-board accessories.
With ultra-compact 11mm*3mm size, it can provide sufficient lasting power for tiny electronic devices without occupying extra internal space of equipment, matching the miniaturization development trend of modern consumer electronics.
In actual procurement and daily replacement, many brands use different coding rules for the same specification battery. The following are fully compatible replacement models of CR1130, which can be directly interchanged without modifying equipment circuits:
Universal Industry Equivalent Model: DL1130, ECR1130, KCR1130 (fully consistent in size, voltage and performance, universal for all equipment)
Cross-border Brand Specific Model: BR1130 (note: BR series is lithium carbon fluoride battery, with slightly lower discharge current but compatible in size; can be used as a backup replacement for low-power equipment only)
Model That Cannot Be Replaced: CR1125, CR1116 (different thickness leads to poor assembly, do not replace blindly)
Replacement Suggestion: For precision equipment such as motherboard backup power and high-precision sensors, prioritize standard CR1130/DL1130; avoid BR1130 for equipment requiring instantaneous large current output.
Combined with its low-current long-discharge characteristics and miniature size, CR1130 is concentratedly used in low-power miniature electronic devices, covering consumer electronics, industrial intelligence, automotive electronics and office supplies:
Mini electronic watches, smart glasses, bluetooth earphone compartment backup power, small LED flashlights, electronic thermometers and portable cosmetic magnifying mirrors. These devices have low daily power consumption and match the long-standby advantage of CR1130 perfectly.
Part of car remote control keys, tire pressure monitoring sensor backup batteries, smart door lock auxiliary power supply, infrared remote controls for small household appliances. Its excellent temperature resistance adapts to complex vehicle and indoor and outdoor temperature environments.
PCB motherboard CMOS backup power for industrial control boards, RFID electronic tags, miniature pressure sensors, medical wearable monitoring equipment, and electronic counters. Stable voltage ensures long-term error-free operation of precision circuits.
CR1130 batteries with positive and negative pole tabs are widely customized by electronic manufacturers, which can be directly welded on PCBs without battery holders, reducing product assembly volume and improving overall structural stability of finished electronic products.
Prohibit charging: CR1130 is a primary battery, charging will trigger chemical reaction inside the battery and cause safety accidents.
Positive and negative installation distinction: The smooth steel shell side is the positive pole, and the matte gasket side is the negative pole; wrong installation will lead to equipment failure.
Storage specification: Keep batteries in dry and normal temperature environment, avoid humid environment and direct sunlight to prevent liquid leakage.
Discard treatment: Waste lithium batteries belong to hazardous electronic waste, please put them into special battery recycling bins instead of domestic garbage.
Although the CR1130 coin battery is a miniature inconspicuous power component, it undertakes critical power supply and backup power functions for countless precision electronic devices. Its 3.0V stable voltage, 10-year long shelf life and wide temperature working performance make it irreplaceable in the low-power miniature battery market. Mastering its parameter indicators, compatible models and application scope can help users avoid wrong selection and replacement failures, and maximize the service life of electronic equipment.
