5 Practical Tips for Using Lithium-Ion Batteries
Lithium-ion batteries are not as “picky” as their nickel-metal-hydride counterparts, but still require some care. Adhering to five simple rules , you can not only extend the life cycle of lithium-ion batteries, but also increase the operating time of mobile devices without recharging.
Do not allow full discharge. Lithium-ion batteries have no so-called memory effect, so they can and, moreover, need to be charged, without waiting for the discharge to zero. Many manufacturers calculate the lifetime of a lithium-ion battery by the number of full charge cycles (up to 0%). For high-quality batteries, this is 400-600 cycles . To increase the life of your lithium-ion battery, you often charge your phone. Optimally, as soon as the battery charge indicator drops below the 10-20 percent mark, you can put the phone on charge. This will increase the number of discharge cycles to 1000-1100 .
Experts describe this process by such an indicator as Depth Of Discharge. If your phone is discharged to 20%, then the Depth of Discharge is 80%. The table below shows the dependence of the number of discharge cycles of a lithium-ion battery on the depth of discharge:
Discharge every 3 months. A full charge for a long time is just as harmful for lithium-ion batteries as permanently discharging to zero.
Due to the extremely unstable charge process (we often charge the phone as necessary, and where it will turn out, from USB, from the socket, from an external battery, etc.), once every 3 months it’s recommended to completely discharge the battery and then charge it to 100% on charge 8-12 hours. This helps to reset the so-called top and bottom battery charge flags. Read more about this here .

Keep partially charged . The optimal condition for long-term storage of a lithium-ion battery is a charge level of 30 to 50 percent at a temperature of 15 ° C. If you leave the battery fully charged, its capacity will decrease significantly over time. But the battery, which for a long time was collecting dust on a shelf discharged to zero, most likely is no longer a long-term tenant - it's time to send it for recycling.
The table below shows how much capacity remains in the lithium-ion battery, depending on the storage temperature and charge level during storage for 1 year.
Use the original charger. Few people know that in most cases the charger is built directly into mobile devices, and the external network adapter only lowers the voltage and rectifies the current of the household power grid, that is, it does not affect the battery directly. Some gadgets, such as digital cameras, lack a built-in charger, and therefore their lithium-ion batteries are inserted into an external “charger”. This is where the use of an external charger of dubious quality instead of the original one can adversely affect the performance of the battery.
Do not overheat. Well, the worst enemy of lithium-ion batteries is high temperature - they do not tolerate overheating at all. Therefore, do not allow mobile devices to come into direct sunlight, and also do not leave them in close proximity to heat sources, such as electric heaters. Maximum allowable temperatures at which lithium-ion batteries can be used: from –40 ° C to + 50 ° C
