1. Internal Resistance:
A practical electrical power source may be represented as an ideal voltage source in series with an impedance. This impedance is termed the internal resistance of the source. When the power source delivers current, the measured voltage output is lower than the open circuit voltage; the difference is the voltage drop caused by the internal resistance.
A battery as a voltage source in series with a resistance. Practically, the internal resistance of a battery is depends on its size, chemical properties, age, temperature, and the discharge current.
2. Charge - Discharge Cycle Life:
It denotes how many times a battery can be charged and discharged. The higher the charge discharge cycle battery life is longer.
3. Charge Time:
This is the time taken by a battery to full charge after a deep discharge.
4. Overcharge Tolerance:
This parameter shows that if we connect a battery with charger and remains connected after fully charged, then how much a battery is prone to permanently damage. It is called Overcharge tolerance.
5. Self discharge/Month:
This defines the shelf life of a battery. If a fully battery putted in unused condition then how long the charge will be maintained. In a month how much charge is gone.
6. Cell Voltage:
As i told previously a battery is a group of cells. The cell voltage is the voltage of individual cell.
7. Charge Cutoff voltage:
When charging a battery when we need to disconnect the charger, the voltage level is reached to its maximum is called Charge cutoff voltage. If we didn't disconnect charger after reaching to its maximum voltage, the battery may be damaged permanently.
8. Discharge Cutoff voltage
It denotes how many times a battery can be charged and discharged. The higher the charge discharge cycle battery life is longer.

7. Charge Cutoff voltage:
When charging a battery when we need to disconnect the charger, the voltage level is reached to its maximum is called Charge cutoff voltage. If we didn't disconnect charger after reaching to its maximum voltage, the battery may be damaged permanently.
8. Discharge Cutoff voltage
This is the minimum voltage level of the battery that could be permissible without damaging it. If a battery extremely deep discharged shortens the battery life.
9. Peak Load Current(non-permissible):
This is the highest current can drawn from a battery without short circuiting it. It ma affect the battery life.
10. Peak Load Current(permissible):
This is the highest current can drawn from a battery without short circuiting it. It does not affect the battery life.
