How to Calculate Run Time of CR1632
Many factors affect battery longevity, including operational temperature, discharge current, dynamic loads, etc. But, for simplicity, let’s pretend we’re powering a standard load of roughly 15K ohms at 20°C. In that situation, our battery’s capacity is 130mAh. This indicates that if we pull 130mA from our battery, it will last 1 hour, and if we draw 65mA, it will last 2 hours.
However, because these batteries are rated for a low output current, the battery should last for (130/0.19) 684 hours if our load consumes just 0.19mA. This statistic, however, will not be correct due to the system’s fluctuating current and operating temperature. A tidy graph can also be found on the CR1632 data page, which can be comprehended in the same way.
Internal Resistance Characteristics
The battery’s internal resistance is another crucial factor to consider when choosing a battery. Unfortunately, every battery has some internal resistance, which prevents you from drawing the full electricity from it. The higher the IR of the battery as it ages or due to its operating environment, the more current you will draw from it and the better the battery’s performance.
The lower the IR of the battery, the more current you will draw from it and the higher the battery’s performance. The continuous outflow at 15k ohms during a Pulse Test at 25°C is 0.19mA @ 2.9V. And at 400 ohms, the pulse drain is 6.8mA @ 2.7V every 2 seconds *12 times/delay.
What criteria do you use to select the best Cr1632 battery for your needs?
Brand Value
Every Cr1632 battery manufacturer has a different price. Most brands have a distinct value proposition that distinguishes them from their competitors.
Size
The CR1632 is a button-shaped Lithium battery with a 3V density and high power voltage. Coin pill units are quite small and similar to regular pill units. The first and most important step is to choose the right size. As the digits reflect the battery capacity, make sure they match the original values. 16*3.2mm is the size of a CR1632 battery.’
Safety
The brand name of a respected big brand is printed on the container and the battery cell. Make sure you’re buying high-quality batteries from a known brand or a big company. Batteries with no brand name on the pack could be made in a small plant using old technology. It could lead to a battery leak or explosion, posing a major threat to your family’s safety.
Stability
Different technologies imply varying amounts of stability. Materials and technology influence instability. Many common brands’ shells are constructed of iron or stainless steel, whereas name brands’ shells are nickel coated. Because they are better insulated and more stable, batteries with a nickel-coated shell, a rare metal with exceptionally high precision and a higher cost, can last up to 5 years without leaking.
Durability
A good battery should have the longest potential lifespan. Battery replacement is a chore that no one enjoys. The terms “capacity” and “durability” are often used interchangeably. A good producer or brand mark performance should be on the card packaging or description. The longer the lifespan, the greater the storage capacity. XXXmAh is the capacity of the battery. Please keep your eyes vigilant because some don’t disclose capacity while others make a show of it.
Factors Affecting How Long the CR1632 Battery Lasts
The battery life varies depending on whether the battery is being used to power a device or stored.
When in Storage
This coin battery has a shelf life of about 10 years if kept in ideal circumstances. They’ll be at 90% capacity after 10 years if they’re stored properly, with a discharge rate of 1% per year.
They should be kept in their original packaging to get the longest shelf life. Temperatures of -20°C to 60°C and humidity levels of 35 to 75 percent are ideal storage conditions.
When in Use
When in use, the service life is determined by the following factors:
User Device
They live longer when utilized in applications that need a high current drain or intermittent power pulses, such as keyless entry devices or watch alarms. They are, however, less suited to low-drain applications such as memory backup due to their chemistry.
Operating Temperatures
The temperature should be between -30 and 60 degrees Celsius. Self-discharge accelerates when exposed to temperatures outside this range, shortening the service life.
