Lithium Ion batteries were invented as long ago as 1912 by means of Gilbert N. Lewis, but it was quite a long time before they were developed enough for being launched on a standard market level. This happened within the early 1990’ s with the help of Sony pioneering their business oriented use.
Lithium Ion batteries have many advantages.
They can be constructed in a multitude of shapes and sizes, resulting in them being tailored to available space in the gps unit in which they should be used.
The batteries will also be much lighter than different equivalents, due to the type of the material and therefore the high open circuit voltage when compared to other batteries. This low weight causes it to be ideal in hand held and cellular phones for obvious reasons, and popular in these days of high tech machines.
Another major advantage is that they don't suffer from memory results. This is the circumstance, whereby other rechargeable electric battery, if not fully cleared before recharging, lose their maximum energy capacity with time and thus hold a lot less charge.
They also don't have such a drastic self applied discharge rate as many other batteries – just 5% monthly, compared with up to 30% every month in other battery models. However, Lithium Ion batteries aren't perfect, and there really are drawbacks.
One of these is that their generation depends upon their age – and not the moment from which they happen to be charged, or the number of times they are charged. They begin to lose capacity gradually on the date of manufacture irrespective of the length of charging cycles they possess. Therefore the manufacturing date pays to to know, e specially when there is a big time lapse from manufacture to being utilized e.. g due to make sure you storage.
Some Lithium Ion electric battery (such as laptop batteries) can certainly lose around 20% of the capacity per year, whenever stored at normal temperature. However, when exposed to make sure you prolonged higher temperatures, this figure can increase to as much as 35% per year. Another key factor is the charge levels – when stored in part charged, these figures could be dramatically reduced.
This makes Lithium Ion batteries unsuitable for several applications – such as back off batteries.
The battery must never ever 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 in the event the charge level meets who minimum threshold. For this approach reason, Lithium Ion batteries are made and manufactured specifically with the device they are to power and are also not available as common batteries.
Having said which usually, there are some models available that have an internal circuit to monitor the particular minimum charge level in addition to shut the battery downwards when it reaches this level. These are termed “ smart” batteries.
How you can prolong the life of this Lithium Ion battery
- Charge the battery early and frequently, unlike other rechargeable electric battery.
- If you will not intend to use the battery a long time, charge it to a good of approximately 40% connected with capacity.
- The battery ought to be kept cool. They will probably age faster at better temperatures, so keep as cool as you possibly can when not in benefit from. They can be safely stored within the refrigerator for optimum deterence of aging. (note: they shouldn't be frozen)
- If the nuvi you are using is normally run from a mains power supply (e.. g laptop) which is possible, remove the battery when exercising on mains power. This prevent the battery from being undergo high prolonged temperatures which will shorten it’ s your life.
- Any steps to lessen the heat that the battery is pass through will benefit it’ utes lifespan.
- When paying for replacements, try to try to find a battery that has all the shortest possible time coming from manufacture to retail. (though it might be difficult to find available this information).
In short Lithium Ion batteries would be a very versatile battery, ideal in lightweight applications and never subject to memory results. However, they do degrade at higher temperatures meaning they are not the universal battery solution.
