debunking  myths about li-ion and li-poly batteries  -  lithium ion polymer battery

There are several common myths (
There are more, but most of them are just changes in both)
Around lithium-ion and lithium-polymer batteries, most of them come from the fact that people don't know the difference between the two, and people mistakenly think that what applies to other rechargeable batteries also applies to lithium-based ones. Myth 1 -
Charging the battery when it is not completely exhausted shortens its life, which is called the "memory effect", where the battery gradually loses its maximum energy capacity when charging regularly after only partial discharge. The Truth -
This is a mythical example that stems from the belief that lithium-based batteries behave the same way as other types of rechargeable batteries.
Memory effect is only applicable to nickel-cadmium batteries (Ni-Cad)
, Actually happens on such a slow scale that it takes about a hundred discharge/charge cycles before noticing the effect. Li-Ion and Li-
On the other hand, the poly battery is immune to the "memory effect" and, in fact, will benefit from charging after partial discharge.
This is because lithium-based batteries have a fixed number of discharge cycles after which they will start to lose their charging capacity.
So if you use it with a capacity of up to 50% and then fill it up with electricity, you consume only half of the discharge cycle.
Use it for up to 50% capacity, then recharge again, shorten the charging cycle by another 50%, and so on.
Myth 2: overcharging is dangerous and will explode your battery
Because there is some truth behind it, it is a myth that is broken. Lithium-
Polymer batteries can explode when overcharged.
However, they all have special circuits that can stop or decrease the charging rate when fully charged.
This means a Li-
The polymer battery will only be overcharged if there is a defect, so you need a defective battery before the battery explodes.
Even if the battery is full, you don't have to be afraid to plug it in, just like you just charged your laptop to 100% and decided to keep using AC, because your laptop does not allow you to use its separate graphics card when using battery power.
Still, you have to be rational.
When you don't use the battery for a long time, it's just a bad habit to have a full battery plugged in and charged, and it's also a sign that you're not taking good care of your gadgets.
The problem with the above two myths is that they cause people to actually be harmful to the battery, for example, constantly drain the battery before charging, making sure they pass the set number of discharges faster than normal. Lithium-
Rechargeable battery based is not a new invention in any case, but they are much better than the old nickel
Top-up products based on capacity and ease of use.
Don't waste the benefits they provide just because of the myths handed down by people you don't know.
