  • With a 70AH capacity and 760 cold cranking amps (CCA). Provides reliable performance and long service life, Up to 2 times the cycle life of conventional batteries. If your car's original battery is an AGM type, you must continue using an AGM battery, as your car will not accept a "downgrade" to a flooded battery. Nominal Voltage:12V. Charging Voltage:14.4~15.0V. Acceptable Charging Current:0~21A. Operating Temperature Range: -22°F~158°F.
  • Heat / Cold Resistance: The materials used in the construction of AGM batteries (such as glass fiber mats and specialized separators) have better heat resistance. This allows AGM batteries to maintain their performance and capacity even in the hottest climates, They are also more resistant to extreme temperatures, making them ideal for hot or cold regions.
  • Low Self-Discharge: AGM batteries have lower self-discharge rates compared to flooded batteries. Self-discharge refers to the loss of capacity that batteries experience over time when not in use. In hot climates, when the battery may need to be stored for extended periods or not frequently used, AGM batteries can better maintain charge, providing higher voltage output and easier engine start-up in any climate.
  • Enhanced Safety: AGM batteries have a lower risk of acid leaks and spills compared to flooded batteries. This is because the acid is absorbed and held within the glass fiber mats, reducing the risk of corrosion or damage to surrounding components,this makes AGM batteries more durable and long-lasting, is also two to three times longer than flooded batteries. AGM batteries also have a lower risk of explosion and are safer to handle, making them ideal for high-performance vehicles.
