Recombination of AGM (Absorbed Glass Mat) VRSL
(Valve Regulated Sealed Lead-Acid) Lifeline Batteries
Lifeline AGM Technology Batteries are the culmination of continual improvements since the introduction of this technology in 1985. Dedicated research and development motivated by the desire to engineer an improved sealed battery without compromising safety, Lifeline has refined this new technology to its current state. With proven reliability and safety, the Lifeline AGM Technology Batteries have received great acceptance in both military sea, air and land applications and commercial deep cycle, starting, and standby/back-up (UPS & Photovoltaic) applications.
How They Work: Unlike gel batteries, AGM recombination takes place within the separator in a molecular state, therefore, the Lifeline sealed batteries are safe for Marine/RV, UPS and Photovoltaic applications. The cells are sealed and relief valves provide a safe positive pressure during charging. A fiber floss glass mat with wicking characteristics is sandwiched between the plates for retention of electrolyte. The electrolyte is absorbed and held in place by the capillary action of this glass mat.
By design, the mat is only 90% saturated with electrolyte allowing a portion of the mat to be filled with gas. These gas spaces provide the channels by which the freshly generated gasses, which are in their atomic state and very reactive, are allowed to recombine rapidly and safely. Due to this engineered reaction, and coupled with the purity of the plate material and grid material, Lifeline Batteries have much lower internal resistance and thus can provide higher rates of discharge and quicker rates of recharge. Additionally, this glass mat provides a higher degree of support against shock and vibration than other types of batteries. Lifeline Battery electrical performance is comparable to nickel cadmium batteries without the expense and maintenance.
Not a Gelled Electrolyte: In contrast to the Lifeline AGM design, gelled electrolyte batteries are manufactured using a silica gel and acid mixture. As a semi solid, voids develop between the gel matrix and plate to allow passage of gases. This renders that area of the cell inert thus reducing the capacity of the gel battery. In addition, recombination takes place in a compressed gas state in the space between the plates and the battery lid.
SAFE: LIFELINE BATTERIES EXCEED SAFE BATTERY TESTS
Increased Capacities: Unlike other sealed battery technologies, the AGM battery technology allows for more positive plate material in its cell construction. Therefore, there is an increase in Amp Hours, Reserve Capacity, depth of cycle, cycle life and a reduction of internal self discharge over other sealed batteries.
Unrestricted D.O.T. Shipping: Lifeline batteries are not restricted by air or any other means of transportation. They are classified as non-dangerous, shipped fully charged, and do not have corrosive labels on their shipping cartons.
Lifeline batteries have been tested by an independent laboratory and passed D.O.T. shipping requirements for hazardous materials, 49 CFR Section 173.159. There are no "UN" labels required. (The "UN" label marks a product as hazardous material)
