Frequently Asked Questions

The main components of lithium-ion battery are: upper and lower battery cover, positive electrode sheet (the active substance is lithium cobalt oxide), diaphragm (a special composite film), negative electrode (the active substance is carbon), organic electrolyte, battery shell (divided into two types of steel shell and aluminum shell), etc.

Charging method of LiFePO4 deep cycle battery:

Constant current and constant voltage charging: The battery is first charged at constant current (CC), and when the battery voltage rises to a certain value, the voltage remains constant (CV) and the current in the circuit drops to very little and eventually tends to 0.

Discharge efficiency is the ratio of the actual power discharged to the end voltage to the rated capacity under certain discharge conditions, which is mainly affected by the discharge rate, ambient temperature, internal resistance, etc. Generally, the higher the discharge rate, the lower the discharge efficiency. The lower the temperature, the lower the discharge efficiency.

We have passed ISO9001:2000 quality system certification and ISO14001:2004 environmental protection system certification; our products are CE certified by EU and UL certified by North America, passed SGS environmental protection test, and have obtained Ovonic’s patent license; meanwhile, our products have been insured by PICC worldwide.

01) Charging.

When choosing a charger, it is best to use a charger with the correct termination charging device (such as anti-overcharge time device, negative voltage difference (-dV) cut off charging and anti-overheating induction device) to avoid shortening the life of the battery due to overcharging. In general, slow charging than fast charging to extend the life of the battery.

02) Discharge.

a. The depth of discharge is the main factor affecting the battery life, the higher the depth of discharge, the shorter the life of the battery. In other words, as long as the depth of discharge is reduced, the life of the battery can be significantly extended. Therefore, we should avoid over-discharging the battery to a very low voltage.

b. When the battery is discharged at high temperature, it will shorten the life of the battery.

c. If the design of electronic devices can not completely stop all the current, if the device is left unused for a long time, without taking out the battery, the residual current will sometimes make the battery overconsumption, resulting in battery over-discharge.

d. Mixing batteries of different capacities, chemical structures or different charging levels, as well as old and new batteries, can also cause excessive battery discharge, or even reverse charging.

03) Storage.

If the battery is stored at high temperature for a long time, the electrode activity will decay and shorten its service life.
