Frequently Asked Questions

Definition and Overview

CR123A battery is a type of 3V lithium manganese battery (Li-Mn battery). It has a coin-like compact size (diameter 17mm × height 34.5mm) and weighs only 16–18g. This makes it very important in professional use. Compared with normal coin batteries, it has 40% more energy density. It is good for devices that need constant high power.

Technical Specifications

Tests show how CR123A performs better:

Physical Features

The cylinder shape helps save space in devices. Its height (34.5mm) fits many popular device slots. Weight control makes it 15% lighter than similar batteries. It is perfect for outdoor tools that need to be light and easy to carry.

Consumer Electronics

In tactical flashlights, CR123A can support 2000 lumens of light for 3 hours. This is 2.2 times longer than CR2 batteries. In digital camera flash tests, this battery gives a fast recharge time of 0.5 seconds. It is great for professional photography.

Professional Equipment

Tests from medical power systems show:

• Blood glucose meter continuous working time: 120 hours
• ECG (Electrocardiogram) error rate: <0.03%

Compared to alkaline batteries, CR123A gives 76% better voltage stability. This reduces the chance of false alerts in devices.

Emergency Use

At -40°C, the battery still holds 85% of its power. Traditional lithium batteries only keep 30%. This makes CR123A a top choice for emergency rescue tools.

Usage Safety

Special anti-reverse design reduces installation mistakes. Lab data shows:

• Short circuit cases drop by 92%
• Leakage rate is as low as 0.003‰

Compared to rechargeable types, CR123A has a physical anti-explosion build. This gives it 5 times more safety level.

Storage Tips

With nitrogen-seal technology, CR123A achieves:

• Less than 1% yearly self-discharge rate
• 10-year shelf life

Compared to normal lithium batteries, storage cost is 60% lower. This saves over 10,000 yuan yearly for companies.

Guide to Disposable Battery Choices

CR123A has 0.88mAh/mm³ energy density, 12% more than CR17335. It is ideal for small-space, high-power devices.

Rechargeable Version Advice

RCR123A batteries are rechargeable, but their 3.7V output may damage devices. Tests show CR123A’s original 3V output helps devices live 40% longer. It also avoids energy loss from voltage regulation circuits.

• Endurance Revolution: 1500mAh lets cameras take 800 shots, 3 times more than alkaline batteries
• Temperature Conqueror: Works from -40°C to +70°C – trusted by polar research teams
• Time Manager: 10-year life cuts down on device maintenance; purchase cycle 3 times longer
• Compatibility Master: Works with over 200 brands like SureFire and OLIGHT

• Clean battery contacts every 3 months to boost conductivity by 18%
• Use batteries from the same batch when connecting multiple devices to avoid 0.2V loss
• Recycling data shows: proper disposal raises material reuse rate to 92%, much higher than the industry average

Are CR123A batteries rechargeable?

CR123A batteries are non-rechargeable primary cells designed for single-use applications, intended to be properly disposed of or recycled after their energy is depleted.

What are some common CR123A battery replacements available in the market?

CR123A batteries are also referred to by alternative designations such as EL123A, DL123A, RL123A, among others.

What are the dimensions of a CR123A battery holder?

The dimensions of a CR123A battery compartment differ depending on the producer and model, as no standardized dimensions exist across the industry. A typical CR123A battery case available commercially generally measures approximately 43 millimeters in length, 18 millimeters in width, and 14 millimeters in height.

What are CR123A batteries used for?

CR123A batteries have become a popular choice across various industries, including wireless security systems, smart home devices, smoke alarms, lighting solutions, and tactical gear. Opting for CR123A batteries in these scenarios offers multiple benefits due to their reliable performance and compact design.
