Imagine responding to an emergency but being unable to do a simple life-saving test or procedure because there is no power to run the device? Imagine someone dying because their pacemaker cell is damaged? Battery packs for medical equipment are quite literally agents in life and death scenes. The cells enable portability and use of the devices when the main power is out.
One common type of cells is called Zinc air. This is just a cell that oxidizes zinc with oxygen from the air. Experts say that as long as the cell is kept in an airtight package, it has a shelf life of up to three years. As soon as it gets exposed to the air, degradation starts. This may be thought to be one of the cheapest options out there. It replaced the mercury zinc oxide cells which were banned by legislation.
A more standard type is the Lithium iodide. This is more commonly used in medicine. It uses lithium as an anode. Unlike the aforementioned type, it is fairly expensive. It is also very long serving. It is said that with proper use and maintenance, this cell can b used for up to 15 years. It also has a long charge life.
One of the key components of cells and their suitability for any device is the chemistry. The chemistry determines whether the cells will run that device efficiently. Chemistry will also determine how long it will stay in use. The chemistry might also compromise the device itself. That is if it is not appropriately analyzed. One aspect of chemistry is the internal resistance. This is a phenomenon that causes the cell to heat up excessively and causing a drop in voltage, therefore, causing a shortcoming in functionality.
Without a bit of tweaking, a cell will not be working at its best in very high ambient temperatures. Over time the cell structure will break down. In general, the cell will not give as much service as it would have an optimum temperature. In the short term, the contrary will be perceived. Optimum temperature is considered to be room temperature.
Does everyone like a cell that charges quickly, right? This is not a good thing, while convenient, it is not good for the long-term wellness and functionality of the cell. This is due to the chemical and physical changes brought about by fast charging. This degradation might also affect the structure of a device.
The bottom line is that one should go for a cell that holds power for a long time. One that can run the device for as long as possible. Remember these are used in life and death situations. It is best if they can provide service for longer rather than the alternative.
As a reminder, try to keep these cells fully charged and ready to go at all times. Have extras too. A cell could have degraded in the chaos of a trauma. An important tip, read the instructions on the packaging. These are good at guiding the use of the batteries and ensuring longevity.
