Description

Concorde's AGM technology was originally developed in 1985 for military aircraft where power, weight, safety and reliability were paramount considerations. We've incorporated this technology in the LIFELINE Series of maintenance-free deep-cycle batteries for your electronics, housekeeping and engine starting requirements.

AGM Technology - The Difference
Some of the main differences between the old vented acid batteries and the LIFELINE AGM valve regulated sealed lead-acid batteries are:

• The electrolyte is absorbed in a glass mat (AGM) seperator in the LIFELINE and it is spillable in the flooded or vented type.

• The cells have pressure relief valves in the LIFELINE that are designed to keep positive pressure in each cell. The older vented or flooded type battery cells are open to atmosphere through the vent cap holes (should the vented battery be tilted or inverted, the result can be electrolyte (a sulfuric acid/water mixture) spilled all over your equipment, a highly corrosive and potentially dangerous condition).

• The cell groups in the old vented type batteries are loosely packed and thus have high plate seperation. In contrast, the LIFELINE AGM marine battery has every square inch of positive and negative plate material tightly packed and compressed with the AGM and supported by the walls of each cell.

With this type of construction, LIFELINE batteries offer much lower internal resistance...greater starting power (particularly in cold temperatures)...and a much higher degree of protection against shock and vibration than the old flooded batteries.
