The Deka Solar Valve-Regulated Gel Monobloc series offers reliable, versatile, maintenance-free power. The thixotropic gel enables these batteries to be
completely spillproof providing many available optionsfor installation. The gelled electrolyte gives more
protection to the battery plates, and is better suitedfor deep cycle discharge. With longer discharge and less charging time, these batteries are ideal
for many renewable energy applications.
Deka Solar Flooded Monobloc batteries are designed tooffer reliable, low-maintenance power for renewable energy applications where frequent deep cycles arerequired and minimum maintenance is desirable. The Deka Solar Flooded Monobloc series include
3 cell (6 volt) and 6 cell (12 volt) batteries.

ENVIRONMENTAL PROTECTION PROGRAMDistillation and Treatment Plant reducing the use ofprecious ground-water by over 100,000 gallons perday. Companywide sustainability initiatives arespread throughout its facilities such as collectionsto recycle paper, cardboard, plastic, used aluminumcans, and glass bottles.
East Penn was one of the first in the nation to installa scrubber unit, which eliminates sulfur dioxide emis-
sions. The company continuallymonitors the ambient emis-sions around its plant site,which continues to decline evenwith a steady increase in pro-duction. The company’s modern facilities as well as its long-standing “green” culture hasmade East Penn the most environmentally conscious proactive battery manufacturer,and recycler in the world.

BULK CHARGE STAGE
TIME CALCULATION
Max Time (Hr) = (Ahr x 1.2) / Avg. Current (A)
Ahr = Amp hours removed during discharge.
1.2 = Recharge multiplier
Avg. Current= Average current available to battery from charger.
Note: Avg. Current should be .s. limits expressed in preceeding chart
Max Time (Hr) - Maximum charge time for battery to reach 80% - 90% state of charge
EXAMPLE OF TYPICAL
3 STAGE CHARGER
Bulk Charge Stage - Current is applied to the batteries at the maximum safe rate they will accept until voltage rises to near (80-90%) full charge level. The battery voltage rises because the charging current that is provided by the battery charger is replenishing its internal charge capacity. The charger current is flat (constant) and the battery voltage is rising.
EXAMPLE OF TYPICAL
3 STAGE CHARGER (can't)
Absorption (Regulation) Stage - The charger will attempt to hold its output voltage constant while the battery continues to absorb charge (draw charging current) from the charger. The rate at which the battery continues to absorb charge in this mode gradually slows down. The amplitude of the charger current is gradually decreasing. The charge current is falling and the battery voltage is flat (constant).
Float Charge - The optimum voltage level at which a battery string gives maximum life and full capacity.
Equalize Charge - A charge, at a level higher than the normal float voltage, applied for a limited period of time, to correct inequalities of voltage, specific gravity, or state of charge that may have developed between the cells during service.
Note: Equalize charging not required on VRLA (AGM / Gel) as part of a daily charge setup. Based on PV applications, unpredictable recharge availability, periodic equalize may be required. Consult EPM (East Penn Mfg) for recommendations.

GLOSSARY
AGM - Absorbed Glass Mat - A class of VALA (Valve Regulated Lead-Acid) battery in which the electrolyte is absorbed into a glass mat.
Ambient Temperature - The average temperature of the battery room. Temperatures below 77°F (25°C) will reduce battery capacity. Temperatures above 77°F (25°C) will reduce battery service life.
Amp Hour (Ah) - Amps times Hours
C20 - Battery capacity measured in Ah (amp hour) at the 20hr rate.
End Voltage - The minimum voltage at which a DC system will operate.
Flooded - A battery in which the products of electrolysis and evaporation are allowed to escape to the atmosphere as they are generated. Electolyte is free flowing throughout the battery.
Gel - A class of VALA (Valve Regulated Lead-Acid) battery in which the electrolyte is immobilized in gel form (sulfuric acid mixed with silica).
Overcharge - The number of ampere-hours (Ah) charged divided by the number of Ah discharged times 100. Typical overcharge values are between 105% and130%.
Temperature Correction - A factor used to compensate for battery capacity and/or adjust battery voltage at ambient temperatures greater than or less than 77°F (25°C).
Undercharge (Deficit charge) - Charging a battery with less ampere-hours (Ah) than is required to return the battery to its initial state-of-charge. This results in a reduction in the battery state-of-charge.
VPC - Volts per Cell
VRLA - Valve Regulated Lead Acid - a lead-acid cell / battery that is sealed with exception of a valve that opens to the atmosphere when the internal gas pressure exceeds atmospheric pressure by a pre-selected amount. VALA batteries provide a means for recombination of internally generated oxygen and the suppression of hydrogen gas evolution to limit water consumption.
