Lifeline® AGM batteries are valve-regulated, recombinant gas, absorbed electrolyte, lead acid
batteries. The cells are sealed with a pressure relief valve that prevents gases within the battery
from escaping. The positive and negative plates are sandwiched between layers of glass mat
consisting of a blend of glass micro fibers of varying length and diameter. This blend features
superior wicking characteristics and promotes maximum retention of the electrolyte. An
envelope of micro porous polyethylene surrounds each wrap of glass mat to further protect the
plates from shorting. Electrolyte is absorbed and held in place by the capillary action between
the fluid and the glass mat fibers. The mat is over 90% saturated with the electrolyte. By design
it is not totally saturated with electrolyte, a portion is filled with gas. This void space provides the
channels by which oxygen travels from the positive to the negative plates during charging.
When the oxygen gas reaches the negative plate, it reacts with lead to form lead oxide and
water. This reaction at the negative plate suppresses the generation of hydrogen that otherwise
would come off the negative plate. In this manner, virtually all of the gas is “recombined” inside
the cell, eliminating the need to add water, resulting in “maintenance free” operation.
Furthermore, since the acid electrolyte is fully absorbed in the AGM separator, the battery is
nonspillable even when turned upside down.
GPL-24T and GPL-27T also incorporate strap handles.
Handles not available on part numbers GPL-4CT and GPL-6CT.
Models GPL-4D & GPL-8D are equipped with rope handles.
Ratings: Capacity ratings are stated at 77° F (25° C) to 1.75 volts per cell.
Completely discharging a battery significantly reduces it's cycle life,
and lifespan. To optimize battery life, discharge batteries to 50%
