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.
Though not very common in medicine, the Zinc-air is one type of cell used to run such devices. The science is actually quite smart and therefore makes the production cost very low. For that reason, this could very well be the cheapest option. The cells pull oxygen from the air and oxidize the zinc in there. The only issue is that it has a short life.
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.
When determining the suitability of a specific type, one looks at the battery chemistry. This is all about the technical functionality of the batteries. It is about the chemical processes that occur once the cells are engaged. It may even extend to the possible processes after an engagement that could lead to degradation. One of these is the internal resistance. The internal resistance should be matched to the load requirement of the device for best performance.
Any cell regardless of where or how it is used works best at room temperature. Some advice that a higher ambient temp is ideal. It may be. Though the positive effect is only short term. In the long term, the cell structure is compromised and life is shortened.
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.
Some cells do not require manual charging. Especially those that are only in place as backup power sources. If the batteries require manual charging, someone should have the responsibility to ensure they remain fully charged at all times. The same person should ensure to keep extras.
