Detailed Description

free maintenance lead acid battery 4~300Ah NPseries KEY FEATURES 1.Good reliability and stable quality :The unique construction and sealing technology ensure that no electrolyte leakage nor bulge nor cracking can occur during normal usage. Excellent discharge performance: Steady discharge current and mild discharge platform 2. Good ability to bear vibration: when the batteries are in the state of fully charge as well as complete fixed. By 4mm swing, frequency of 16.7 Hz, no spilling occurs, no bulge and no cracking with well-balanced open circuit voltage. 3. Excellent endurance for impact: No spilling nor bulge nor cracking occur and well balance open circuit voltage for the fully charged battery fall down from 20CM high for three times. 4. Exceptional discharge recovery performance: Discharge the fully charged batteries for three weeks by the fixed resistance (equal to the requested resistance of 1 Ca discharge of this battery) in the temperature of 25C –Low self discharge characteristic. The capacity comeback is 75% 5.Exceptional charge acceptance :Charge the fully charged battery by 0.1Ca for48 hrs the battery still keep the well-balance open circuit voltage and no spilling nor cracking occur 6.Good endurance for strange current :Discharge the fully charged battery for 5 minutes by 2Ca or 5second by 10Ca, no melt occur for the part of up conduction of electricity and no distortion for the appearance of the battery.
