What will happen to lithium ion batteries if they are not used for a long time?

The lithium battery industry development is very rapid, and it also has wide application. We can say that our life of science and technology has been inseparable from the lithium battery. At present, the market tends to use 18650 lithium battery. Compared with traditional lead-acid batteries, lithium batteries have advantages of high open circuit voltage, low self-discharge, high discharge rate, wide working temperature range, fast charging, no memory effect, no pollution, etc.

Never use the new stock: under normal circumstances lithium battery pack the factory GB charge is 30%.Such as:18650 battery14.8 V / 2200 mAh capacity, the factory capacity is about 600-700 mAh. But the lithium battery will discharge batteries themselves, also is what we usually call the leakage.

Battery protection board has a lot of electronic components, IC, MOS, capacitance, resistance and so on their own will also continue to the consumption of electricity, plus batteries own self-discharge (all rechargeable batteries, lithium batteries, polymer battery、lithium iron phosphate batteries, nickel metal hydride batteries are the same) although the self-discharge volume is small, a few micro amps/hour like this, in the process of normal use of a few call can slightly, but if long time need not, be it is not small, one hour a few micro amps, * down could reach 1-2 Howe.

So in 14.8 V / 2200 mAh, for example, the factory 30% of about 600-700 mAh capacity is more than a year would be completely dry leakage, if the battery assembly on the product, then combined with some of the above products electronic components, may leak faster, time is shorter. When the dew did complete when the lithium battery power, batteries, diaphragm paper completely dry rotten, electrolyte to "0" thoroughly, can't active, also cannot charge back. Some customers may speak, that a full battery factory when your good isn't a lot you, for this problem is really much better, but the factory power with full, very unsafe, so the industry standard is everyone charged 30%.

Used: used to discharge the battery pack into the protected, also is the basic power after state (in fact, only a little more than electricity state).Under the condition of the normal use, when the lithium battery discharge voltage protection, automatic shutdown protection board, lithium battery power nearly finished state at this time, about 5% more than just some electrical parts, normally finished filling, sometimes busy forget it after a few days at once again no matter, basic charge again half a month, a month, problems are slim. But ran out of this situation if put three, four months without charge whatever it's pretty much scrap.

To solve these problems, we just have no problem to do the following,

* : new battery if never used, please don't put too long. Especially the new battery unused, don't throw is four, five months. If really can't be out in time off, please remember to fill the battery!

Secondly, if it has shipped the goods, it needs to mark for the customer on the product manual. If don't charge the new product for long time, the battery will fail. If run out of electricity normally, recharge it on time. Otherwise, the battery will fail.
