How to maintain Li-battery

Friends who have purchased Justsends' emergency ventilator and transport ventilator may be confused about how to maintain the built-in lithium battery of the ventilator. Let's talk about this briefly, so that you can gain something:
1.The work temperature of Li Battery should be kept in indoor temperature, if the temperature is too high (more than 45 degrees centigrade) or too low (less than 5 degrees centigrade), the life of battery will be reduced; 
2.Storage: The capacity will be reduced quickly during the static initial stage (1 month); during the 1-2 months, it will be reduced few; and during 2~3 months, the capacity will be reduced obviously. So, if is not used for a long time, it should be checked regularly.
3. If it is laid up for a long time, the charge time should be in 3~4 hours; if it is lack of capacity, the charge time should be in 2~3hours; if the battery is lack of capacity for a long time, the charge time should be in 8~10 hours;
4.Charge Time: The battery charge of this equipment is similar to the battery charge of cellphone. If you want to play a best role of the battery, you'd better use it usually, letting the electrons in the lithium battery are always in a state of flow. If you do not use it usually, please recharge it every month, doing a power calibration. that is to say, deep discharging and deep charging once:
5. After finishing full charge, you'd better take out of the end connected with the charger first, and
then take out of the other end connected with the AC Adapter connector;
6.You'd better do not use the ventilator when charging.
