1. the use of environmental temperature

Be sure to give the battery to work properly at the right temperature and keep going, in terms of general battery, should ensure that the temperature of its environment between 20-25 degrees Celsius, and lithium-ion battery UPS can work normally at -20-60 degrees Celsius, do not air conditioning, reduce equipment installation costs, maintenance costs, electricity costs.

2. regular checks should be conducted

Regularly check the terminal voltage and internal resistance of each unit battery. Lithium-ion battery UPS power supply in the course of operation, due to changes in the characteristics of each cell battery over time and the above imbalance is no longer possible to rely on the lithium-ion battery UPS power supply internal charging circuit to eliminate, so the characteristics of this has occurred significantly unbalanced battery pack, if not taken offline in a timely manner even charging treatment, its imbalance will become increasingly serious.

3. certain conditions to refloat the charge

The lithium-ion battery UPS power supply shutdown for more than 10 days, before restarting, the UPS power supply should be started under the conditions of no load to use the charging circuit in the machine to re-float the lithium-ion battery for more than 10 to 12h before running with load. If this state lasts too long, resulting in lithium-ion battery failure and scrap due to excessive storage, it is important to show the increase in internal resistance of the battery, serious internal resistance up to a few.

4. the need to reduce the depth of discharge

The service life of the lithium-ion battery UPS is closely related to the depth of its discharge. The lighter the load carried by the lithium-ion battery UPS power supply, the greater the ratio of the available capacity of the lithium-ion battery to its rated capacity when the utility power supply is interrupted.

When the lithium-ion battery UPS power supply in the utility power supply interruption, the lithium-ion battery to the inverter power state, the vast majority of lithium-ion battery UPS power supply will be a gap of about 4s sounding a periodic alarm to notify the user is now supplied by the battery energy. When you hear the alarm become urgent, it means that the power supply is in deep discharge, you should immediately carry out emergency treatment, shut down the lithium-ion battery UPS power. Not as a last resort, generally do not let the lithium-ion battery UPS power supply has been working until the end of the automatic shutdown due to low battery voltage.

5.Can use the power supply peak charging

On the lithium-ion battery UPS power supply for a long time in the utility low voltage power supply or frequent power outages for users, in order to prevent premature damage to the battery due to long-term undercharge, should make full use of the power supply peak (such as late at night time) to charge the battery to ensure that the battery has sufficient charging time after each discharge. Generally, after the battery is deeply discharged, it takes at least 10-12h to recharge to 90% of the rated capacity.
