Lithium Ion batteries were invented as long ago as 1912 just by Gilbert N. Lewis, but it was quite a long time before they were developed enough to get launched on a standard market level. This happened within the early 1990’ s with Sony pioneering their professional use.
Lithium Ion batteries have several benefits.
They can be constructed in a multitude of shapes and sizes, resulting in them being tailored to the available space in the 780 in which they should be used.
The batteries will also be much lighter than other sorts of equivalents, due to the nature of the material additionally, the high open circuit voltage as opposed to other batteries. This low weight causes it to be ideal in hand held and mobile devices for obvious reasons, and popular in these days of high tech machines.
Another major advantage is that they don't suffer from memory appearance. This is the circumstance, whereby other rechargeable batteries, if not fully dismissed before recharging, lose their maximum energy capacity with time and thus hold reduced charge.
They also don't have such a drastic home discharge rate as other batteries – just 5% monthly, compared with up to 30% a month in other battery designs. However, Lithium Ion batteries aren't perfect, and there are drawbacks.
One of these is that their life span depends upon their get older – and not the time from which they are charged, or the number of times they have been charged. They begin to lose capacity gradually through the date of manufacture irrespective of the amount of charging cycles they need. Therefore the manufacturing date is useful to know, e specially when there is a big time lapse from manufacture to being employed e.. g due to storage.
Some Lithium Ion batteries (such as laptop batteries) may well lose around 20% of the capacity per year, whenever stored at normal conditions. However, when exposed to prolonged higher temperatures, this figure can increase to as much as 35% per year. Another key factor is the charge tier – when stored in part charged, these figures could be dramatically reduced.
This makes Lithium Ion batteries unsuitable for several applications – such as back up batteries.
The battery must certainly not be discharged below a particular threshold, otherwise the battery is going to be damaged irreversibly. Therefore, the devices that use them have a built in system to shut them down if your charge level meets who minimum threshold. For this reason, Lithium Ion batteries are made and manufactured specifically to the device they are to power and they are not available as common names batteries.
Having said that, there are some models available that have a built in circuit to monitor a minimum charge level and even shut the battery off when it reaches of which level. These are known as “ smart” batteries.
How you can prolong the life of your respective Lithium Ion battery
- Charge the battery early and frequently, unlike other rechargeable batteries.
- If you you should never intend to use the battery for a long time, charge it to a level of approximately 40% involving capacity.
- The battery ought to be kept cool. They will certainly age faster at more significant temperatures, so keep as cool as you possibly can when not in usage. They can be safely stored in a refrigerator for optimum prevention of aging. (note: they shouldn't be frozen)
- If the device you are using can often be run from a mains power (e.. g laptop) which is possible, remove the battery when using mains power. This prevent the battery from being subjected to high prolonged temperatures which often can shorten it’ s life.
- Any steps to lessen the heat that the battery is subjected to will benefit it’ utes lifespan.
- When getting replacements, try to get a battery that has typically the shortest possible time out of manufacture to retail. (though it might be difficult to find out and about this information).
In short Lithium Ion batteries are a very versatile battery, ideal in lightweight applications and never subject to memory result. However, they do degrade at higher temperatures meaning they are not a universal battery solution.
