GLOSSARY OF TERMS FOR VALVE-REGULATED LEAD-ACID BATTERIES - CONT.
NOMINAL VOLTAGE
A nominal value to indicate the voltage of a cell
battery. Generally, nominal voltage value of a
battery is somewhat lower than its electromotive
force. Nominal voltage of the lead-acid battery is
2.0 V per unit cell.
OPEN CIRCUIT VOLTAGE
Measured voltage of a cell/battery which is
electrically disconnected from the external
circuit.
OVERCHARGE
Continued charging of a fully charged cell/
battery. With batteries which require watering,
overcharge causes electrolysis of water,
resulting in rapid decrease of electrolyte.
Generally, overcharge adversely influences
battery life.
OVERDISCHARGE
Discharge of a battery to a voltage below a
predetermined cut-off voltage.
PARALLEL CHARGE
Simultaneous charging of two or more batteries
connected in parallel. In cyclic use of batteries,
specifically, the parallel charge tends to cause
an imbalance in charge state among the
batteries, which may shorten their service life.
POLYPROPYLENE RESIN
A plastic material which is often used for the
case and cover of batteries.
POSITIVE PLATE
The battery electrode from which a current flows
to the external circuit during discharging. The
positive plate has higher electric potential than
the negative plate to the electrolyte. The positive
plate is incorporated with connection parts such
as the electrode pole.
QUICK CHARGE (RAPID CHARGE)
Charging in a short time with a large current.
RATED CAPACITY
The stated capacity of a battery; namely, the
ampere-hour amount which can be drawn from
the battery in fully charged state at a specified
temperature, at a specified discharge rate, and
to a specified cut-off voltage. The symbol CN
may be used to express the rated capacity of N-
hour rate.
VRLA BATTERIES PAGE 64
RECHARGEABLE BATTERY
The rechargeable battery is a system
comprising two different electrodes and an ion-
conductive medium, which is capable of
converting chemical energy to electric energy,
and vice versa. It is also called a secondary
battery.
REFRESH CHARGE (AUXILIARY CHARGE)
Charging of a battery mainly to compensate for
its self discharge.
RESIDUAL CAPACITY
Residual capacity of a battery after partial
discharge or after storage for long time.
RETAINER TYPE
A method to control flowing electrolyte in a
battery with the retainer mat, etc..
REVERSE CHARGE
Charging of a battery with its polarity reversed.
Namely, the battery discharges.
SELF DISCHARGE
Reduction in capacity of a battery while no
current is drawn by the external circuit. Self
discharge depends on temperature: amount of
discharge approximately doubles by each
(10°C) rise of ambient temperature.
SEALED LEAD-ACID BATTERY (SLA
BATTERY)
See: Valve-regulated lead-acid battery. (VRLA)
SEPARATOR
A porous or microporous liquid-absorbent
material which is installed between the battery
electrodes for preventing short-circuit, securing
the separation of the electrodes and retaining
electrolyte. The separator should be resistant to
oxidation and chemicals; it should excel in
electric insulation and liquid-retention; and it
should not disturb diffusion of the electrolyte and
ionic conduction.
