Some of the main differences between the old vented lead acid batteries and the LIFELINE AGM valve regulated sealed lead acid batteries are:
• The electrolyte is absorbed in a glass mat (AGM) separator 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 (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 separation. In contract, 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 offers much lower internal resistance ... greater starting power (particularly in cold temperature) ... and a much higher degree of protection against shock and vibration than the old flooded type.
