Lifeline® AGM Deep Cycle Batteries
Integrated Power Systems is the Authorized
Midwest Distributor for Lifeline® AGM Deep Cycle batteries.
Originally designed for demanding military applications, Lifeline®
AGM batteries are now being used as standard equipment on
many of the finest luxury motor homes and bus conversions.
Reliability, extended cycle life, safety and true maintenance
free operation are just a few of the reasons Lifeline®
AGM batteries are gaining popularity in the RV OEM market
and aftermarket. Independent testing supports the superior
performance of AGM technology. The batteries are totally sealed
and never require water to be added. No corrosive and potentially
flammable fumes or gasses are produced during normal operation
making the Lifeline® AGM batteries one of the safest on
the market. Lifeline® owners typically experience significantly
higher cycle life and faster recharge times with Lifeline®
About AGM Technology:
AGM stands for Absorbed Glass Mat.
AGM battery technology was designed to provide increased safety,
efficiency and durability. Lifeline® Advanced AGM batteries
are based on liquid lead acid battery chemistry, however the
electrolyte in an AGM battery is absorbed and held in place
by micro-fibrous silica glass mats which are sandwiched between
the lead plates. The electrolyte is still in liquid form and
remains so for the life of the battery. The glass mats are
over 90% saturated with electrolyte allowing the oxygen produced
during charging to migrate to the negative plate and recombine
into water. Because the plates are kept "moist"
instead of "flooded", gas recombination efficiency
is very high (typically 95%). This allows for a sealed valve-regulated
battery case which vents less than 2% hydrogen gas (Over 4%
is needed to support combustion).
This also eliminates water loss and makes the Lifeline®
the safest deep cycle lead acid battery on the market. In
addition to superior safety, AGM technology provides much
faster battery recharge and provides up to three times the
cycle life of leading deep cycle batteries.

A temperature compensated charging source is highly recommended.
AGM construction and technology
significantly reduces the possibility of battery damage and
premature failure due to sulfation (a build up of lead sulfate
on the plates). However, like all lead acid batteries, some
sulfation can occur over time through normal battery use.
In addition, normal battery cycling tends to develop slightly
different voltages internally within each cell over time.
To correct both of these conditions, an "equalizing" or "conditioning
" charge is often recommended. The equalization process involves
charging the battery beyond its gassing state for a specific
period of time on a scheduled basis. Frequency of equalization
depends upon several factors including the quality of your
charging system and how often you cycle your batteries. Performing
an equalizing charge at least once a year is a good maintenance
practice that will prolong the life and performance of your
For long term storage, (more
than 2 months) it is a good idea to lower the float voltage
to 12.9 to 13.1 volts. Prolonged voltage above this level
will tend to dry the cells on any liquid lead acid battery.
Keeping the float voltage lower in long term storage applications
will simply increase the life expectancy of your battery.
