There are many instances in which backup power source for devices at a hospital or health facility might be needed. Say there is a blackout. Or there is a need for extra devices to be set up because the facility is past capacity. Battery packs for medical equipment then come in handy to help save lives. They become the saving grace in emergency situations. More so in remote areas and war zones.
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.
With a longer shelf and charge life is the lithium iodide cell. This is more expensive. It is also quite commonly used in medicine. It may be considered by some as the standard. A third but fading type is the Nickel Cadmium cell. This is being phased out as better options are discovered. Except of course in situations where it is absolutely necessary to use this.
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.
As a layman, one will usually be interested in one thing. The charge life. How long will the charge keep? How long will the device run on the cell only? Is it long enough? Is there some sort of mechanism that allows for a backup cell to be attached?
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.
