[Live matter] The point at which the battery discharge, able to provide electricity on the positive and negative plates of paste, in lead-acid battery, anode material is lead dioxide, cathode material is spongy lead.

[when Ann (Ah)] (ampere hour) Used to define a battery capacity of the unit, when the battery is discharging, with discharge current (amps) for the duration of the discharge left (hours) of the proceeds of the value.

[Effective capacity]In the specified state of charged, discharge rate, temperature and termination voltage, can provide capacity.

[Battery] By two or more than two single cells, are usually connected in series and, sometimes, a single cells can form a battery. [capacity] means the battery can provide power, expressed in ampere hour (Ah), is in a certain environment temperature, in a specified current value, electricity to a lattice constant exile termination voltage (typically 1.75 V/single) the measurement duration time (hours), with the current value (amp) multiplied by the discharge time (hours) it is concluded that the battery discharge capacity (Ah).

[Restore capacity]Also known as recoverable capacity when the battery is in low capacity of the state, through a variety of charging and discharging processes, can receive the discharge capacity.

Single cell can also be called monomer battery, is the minimum unit of storage battery, in lead-acid battery, a single nominal voltage is 2 v, most of the battery is made up of two or more than two single composition, for example of three single 6 v battery; Six of the single 12 v battery.

[Charging] A process of battery to regain power, in the process of charging, the voltage of the battery will be rise.

[Charging efficiency]Is the battery discharge capacity (Ah) and recharging when the ratio of filling the capacity (Ah).

[Constant voltage charging] A kind of charging method, the control voltage of use this method to discharge the battery recharging, the charging current will decrease gradually, constant voltage charging is the most commonly used VRLA battery charging method.

[Constant-current charging]One of the control current charging method, by controlling the charging time, can be fixed into electricity. When the constant current method to VRLA battery, need to install the timer to avoid overcharge.

[Termination voltage] Voltage of the battery at the end of the charge and discharge.

[Loop] Cells following an one time charge and discharge is called a cycle.

[Cycle life of battery] Iin failure before can provide charge cycles, cycle life and the battery discharge depth has a lot to do.

[Recycling batteries] Need to be used after repeated cycle of filling a kind of method.

[Deep discharge]The battery discharge to the rated capacity of 80 ~ 100%.

[Discharge depth] Refers to the battery out the percentage of its rated capacity.

[Discharge] Refers to the process of battery output current.

[Discharge rate] often use a multiple of capacity (C), refers to the battery discharge rate. Such as 0.1 C discharge refers to with a capacity of 0.1 times the current (amps) discharge.

The battery discharge voltage in the terminal voltage in the process of discharge.

[Electrode] Refers to with active characteristics of the positive and negative.

[Conducting ion] in the electrolyte battery, lead acid battery, sulfuric acid aqueous solution.

[Floating] to keep the battery charge is full and continuous charging, the process of the load connected to the battery and provided by current charger.

[Gel electrolyte] Mixed with sulfuric acid aqueous solution by silicon compounds formed by a stagnant jelly, colloid is contained in the thick glass fiber mesh or microporous separator, in this kind of VRLA batteries, gel sheet instead of the more common diaphragm effect of super fine glass fiber materials.

[High rate discharge/charge] With relatively high current density of discharge or the charging process, several practical USES the rated capacity C ratio design depends on the battery charging and discharging.

[Internal impedance/resistance] Battery for a measure of the current block, cause a big or small voltage drop and some degree of heat resistance and impedance (ac) and resistance (dc) value is proportional to, but it is different, the reason lies in the differences in measurement.

[Internal short circuit] To point to inside the battery, the positive and negative plate contact together.

[Life] until the batteries lose characteristic of time and cannot be used again.

[Load outside]The battery power equipment or institutions. The resistance of the load and battery voltage determines the size of the current, as well as the battery run time.

[Maintenance-free] Non-sealed conventional batteries need to be on a regular basis to fill with water, and sealed lead-acid battery don’t have to maintain.

[The rated voltage ] Used to represent the battery voltage rating, in terms of VRLA battery, monomer battery rated voltage is 2 v.

[Open circuit voltage] Without load terminal voltage of the battery.

[The overcharge]Psych has continuous recharge batteries, overcharge will shorten the battery life for a long time.
