Lifeline Batteries Featuring AGM Absorbed Glass Mat Technology
How They Work
For the past 15 years, Concord Battery Corporation has been a leader in the research, development and production on Seal Lead Acid Batteries.
The older flooded electrolyte storage batteries had numerous faults, some hazardous and some merely an inconvenience. They leaked acid and produced abundant quantities of hydrogen and oxygen gases during charge. They required frequent additions of water to replenish that lost by electrolysis and by evaporation.
The LIFELINE Series Battery was designed to correct many of the defects of the earlier batteries. The cells are sealed with pressure relief valves that confine any gases produced during cell operation. These gases are then recombined back into water, substantially eliminating the loss of water from the cells and need for water replenishment.
Early on, some of these features were present in what came to be known as gelled electrolyte battery or GEL-CELL. The electrolyte in these batteries consists of a mixture of finely divided silica or sand mixed with a sulfuric acid solution. The gelled electrolyte is highly viscous and during charge and discharge often develops voids or cracks which impede acid flow and result in loss of battery capacity. As these voids continue to increase, more and more plate area is left dry and unable to provide a path for ionic flow, thus progressively reducing the capacity of the gelled electrolyte battery.
Not a Gelled Electrolyte
In Contrast, the electrolyte in the LIFELINE AGM Series battery is absorbed and held in place by means of a micro fibrous silica glass mat which is sandwiched between the plates. The electrolyte is still liquid and remains so for the battery life. Since the glass mat is only about 90% saturated with acid electrolyte, the oxygen produced during charge can rapidly migrate to the negative plate and recombine into water. This recombination mechanism, and along with charge voltage control, substantially eliminates water loss, making the LIFELINE AGM Series a truly non-spillable, maintenance free battery.
The Life Cycle Performance Chart below shows the advantage of LIFELINE AGM over the standard leading gel battery.
And with LIFELINE you get:
Aircraft class cell construction
Lower internal resistance for high repeated engine start current.
withstands shock and vibration much better than standard flooded or gelled electrolyte designs.
Twice as many discharge/charge cycles as the leading gel battery depending on depth of discharges.
Faster recharge, no current limitations with voltage regulated recharging.
Much better charge retention than low cost, flooded cell types, even at high ambient temperature.
Full recharge after 30 days storage in a full discharge condition (77°F)
Less than 3% per month self discharge at 77°F; less at lower temperatures.
Sealed construction with absorbed electrolyte-no shipment restrictions, submersible without damage; no need for watering.
install in any position
Cell safely vent valves-pressure regulated, non-removable.
Rugged, non-marring polypropylene (copolymer) case/cover.
Safety - even during sever overcharge the LIFELINE AGM battery produces < 2% hydrogen gas (4.1% is required for flammability in air)
