GENERAL INFORMATION ON VALVE-REGULATED LEAD-ACID BATTERIES -
Applications
Features
A required-minimum quantity of electrolyte is
impregnated into, and retained by, the positive and
negative plates and the separators; therefore
electrolyte does not flow freely. Also, the terminal has
a sealed structure secured by long adhesive-
embedded paths and by the adoption of strong epoxy
adhesives which makes the battery leak-resistant.
(Note) In stand-by/back-up uses, if the battery
continues to be used beyond the point where
discharge duration has decreased to 50% of the
initial (i.e. life judgment criteria), cracking of the
battery case may occur, resulting in leakage of the
electrolyte.
Service life of our long-life series (LC-P, LC-X series)
is approximately double that of the conventional LC-R
series batteries (Temperature 25°C, discharge rate
0.25 CA/ 1.75V/cell, discharge frequency every 6
months, 2.30V/cell charge).
Stand-by/Back-up power applications
Leak-resistant structure
Long service life
Main power applications
automated transports, electric wheelchairs,
cleaning robots, electric automobiles, etc.
Communication equipment: base station,
PBX, CATV, WLL, ONU, STB, etc.
Back-up for power failure: UPS, ECR, com-
puter system back-up, sequencers, etc.
Emergency equipment: lights, fire and burglar
alarms, radios, fire shutters, stop-position
controls (for machines and elevators), etc.
Communication equipment: transceivers
Electrically operated vehicles: picking carts,
VRLA BATTERIES PAGE 14
*(Note) When any medical equipment incorporating a Panasonic VRLA
battery is planned, please contact Panasonic.
Unlike the conventional batteries in which electrolyte
can flow freely, VRLA batteries do not need specific-
gravity checks of the electrolyte nor do they need to
have water added; This makes the battery function
fully and makes maintenance easy.
Unlike the conventional batteries in which electrolyte
can flow freely, VRLA batteries generate no sulfuric
acid mist or gases under the use condition we
recommend. In uses under conditions other than
recommended, however, gas generation may occur,
therefore do not design the battery housing with a
closed structure.
As seen in the figure on the next page, our VRLA
battery shows exceptional rechargeablity even after
deep discharge, which is often caused by failure to
turn off the equipment switch, followed by standing
(approx. 1 month at room temperature is assumed).
Easy maintenance
No sulfuric acid mist or gases
Exceptional deep discharge recovery
hedge trimmers, cordless drills, screwdrivers,
jet-skis, electric saws, etc.
critical medical equipment*: measuring equip-
ment, non life-critical medical equipment
(electrocardio-graph), etc.
movie lights, etc.
drives, lights, etc.
tape recorders, other portable equipment, etc.
Tools and engine starters: grass shears,
Industrial equipment/instruments and non life-
Photography: camera strobes, VTR/VCR,
Toys and hobby: radio-controllers, motor
Miscellaneous uses: integrated VTR/VCR,
