How Do Battery Specifications Impact Performance?
Battery specifications significantly influence performance by affecting energy capacity, voltage, discharge rate, and temperature tolerance. Understanding these factors helps in selecting the right battery for specific applications.
Energy capacity: This specification, measured in ampere-hours (Ah) or milliampere-hours (mAh), indicates how much energy a battery can store. Higher capacity results in longer usage time. For example, a battery rated at 3000 mAh can supply 3 Amps for one hour or 1 Amp for three hours. According to a study by Parker and Liu (2019), larger capacity batteries can sustain high-drain devices for extended periods.
Voltage: Battery voltage, measured in volts (V), determines the power a device receives. A battery with a higher voltage can deliver more current to power demanding devices. Most common batteries, like AA, provide 1.5V, while lithium batteries can offer 3.7V or higher. Wang et al. (2020) noted that increased voltage enhances performance in devices requiring rapid energy bursts, like digital cameras.
Discharge rate: This specification indicates how quickly a battery can release energy. It is measured in C-rating, where a higher C-rating allows faster power delivery. For instance, a battery with a 10C rating can theoretically discharge its energy in one-tenth of an hour. The Journal of Power Sources explains that batteries with high discharge rates are essential for applications like drones and remote control vehicles (Smith, 2021).
Temperature tolerance: This attribute defines how well a battery performs under varying temperature conditions. Most batteries function optimally between 0°C and 40°C, but extreme temperatures can reduce their lifespan and performance. The research by Chan and Lee (2022) found that lithium-ion batteries frequently exposed to high temperatures could lose up to 20% of their capacity over time.

Why Is Reliability Crucial When Selecting a CR123 Flashlight Battery?
Reliability is crucial when selecting a CR123 flashlight battery because it directly affects the flashlight’s performance and safety. A reliable battery ensures consistent illumination and long-lasting power. Without reliability, users may experience unexpected failure during critical situations.
The National Institute of Standards and Technology (NIST) defines reliability as “the probability that a product will perform its intended function under stated conditions for a specified period.” Reliable batteries provide predictable performance, minimizing risks associated with power outages in essential tools like flashlights.
Several reasons underscore the importance of reliability in CR123 batteries. First, these batteries are often used in high-stakes situations. For instance, in search and rescue missions, a failed flashlight due to battery unreliability can jeopardize safety. Second, reliable batteries have better quality control standards, meaning they are less likely to leak or explode. Poor reliability may lead to diminished performance or even hazardous situations.
Technical terms like “capacity” and “voltage” are essential to understand battery reliability. Capacity refers to the amount of energy a battery can store, measured in milliampere-hours (mAh). Voltage indicates the electrical potential difference. Both capacity and voltage impact how long a flashlight will operate on a single charge, affecting its reliability during use.
The mechanisms behind battery reliability involve chemical processes. CR123 batteries typically use lithium chemistry, which provides high energy density and efficiency. Over time, chemical reactions within the battery can lead to degradation, resulting in reduced performance. Factors like temperature fluctuations and storage conditions can accelerate this degradation process.
Specific conditions affecting battery reliability include temperature extremes and humidity levels. High temperatures can cause batteries to swell or leak, while extreme cold can reduce capacity. For example, using a CR123 battery in a high-temperature environment may result in unexpected flashlight failure during critical moments. Keeping batteries stored in appropriate conditions can enhance their reliability over time.
