Medicine has greatly benefited from cell innovations. Battery packs for medical equipment are meant to ease portability. They are also meant to act as backup power sources. In remote areas, they come in handy as some tests and life-saving procedures can be done en route to the hospital or nearest facility. They also come in handy in war and travel. Picking the right one can be tricky especially without guidance. Even with guidance, one should know what the professional is talking about.
How about a quick look at some of the common types? The first is Zinc air. This is not quite the standard option in medicine but it has been known to make an appearance. Many many years ago legislation banned the mercury zinc oxide cell. This has been found to be a suitable replacement for that. It has a short shelf and charges life but it has been found to be very affordable. The mechanism of action is oxidation of the zinc with O2 in the air.
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.
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.
Fast charging would be ideal especially for situations where one forgets to charge the batteries or an emergency that requires a quick fill up. Even though it is possible to get such, it is not advisable. There are adverse physical and chemical changes caused by fast charging. These changes shorten the life of the cell. A compromise might even spill over into the device.
Away from the complicated stuff, look for battery life. This is the period during which the cells can run the device before requiring a recharge. It is always better to go with the highest charge life. Who knows what situations will come up? It would be very sad to lose a patient because the charge ran out.
Whatever cells must be manually charged should be kept fully charged at all times. Life in medicine is very unpredictable. The cells should be on standby at any time. There should also be as many extras as possible. Just keep an eye on the shelf life.
