Dual-Purpose vs. Deep-Cycle

• Rather than having a starting battery and a deep-cycle battery, the dual-purpose batteries can handle both jobs at the same time and can be used to start the engine and deliver service power for accessories and electronics.
• AGM Battery has 20x more vibration resistance than flooded marine batteries.
• AGM batteries have 2x more cycle life than traditional flooded marine batteries.
• AGM technology provides superb shock and vibration resistance.
• This battery is designed to handle all accessory demands in RVs and boats.

Charging

• Need full charge AGM battery when the voltage falls to 12.7V.
• AGM battery storage period at 25℃ is 6 months, generally do not need to recharge the battery in 6 months. Storage for more than 6 months, need to fully charge the battery.
• Use constant voltage 14.4± 0.1V, max current 0.2C₂₀A (C₂₀ is battery rated capacity) charging battery. For example, if the power is 55Ah, use max current 11A to charge the battery until the current has no change for 2 to 3 hours. But the maximum charging time must not exceed 24 hours.
