FAQ

• What is charge retention and how to test?

  Charge Retention is characteristics to evaluate self-discharge performance of the cell/battery, usually measured with a discharge current of 0.2C and a discharge final voltage of 2.0V after standard charge and storage time of 28 days.
  
  Criteria: Discharge capacity ≥85% of initial capacity

• Why does a battery discharge time be shorted?

  Normally the battery internal resistance will be increased with more use, then the battery discharge performance will be degraded, and voltage drops more fast, so the discharge time be shorted.

• What is the difference between parallel and series circuits?

  Parallel circuit is involved two or more batteries connected to extend the capacity. In this case, the positive terminals are connected together, and the negative terminals are connected together until the desired capacity reached.Series circuit connects two or more batteries together to increase the voltage. We connect the positive terminal to the negative one until reaching the voltage we need. For example, if we series circuit two batteries with 12V, that will be 24 voltage in total.

• Does the LiFePO4 battery have a memory effect?

  LiFePO4 batteries do not have memory effect. That means deep-discharge cycles are not required. In fact, it's better for the battery via shallow discharge and charge cycles.
