Maintenance-free (no need to add water to the acid plus lifetime). ● Use strict production process, the cell voltage balancing resistance. ● using a special grid alloy, good corrosion resistance and deep cycle performance, self-discharge is minimal. ● absorbed glass fiber technology allows up to 99% gas recombination efficiency and low internal resistance, excellent high-current discharge performance. 4. MF Lead Acid Battery Installation Requirements ● Check the batteries before using the appearance of cracks, breakage, leakage phenomenon, once discovered in time to find the cause or be replaced. ● The battery should be installed away from fire, heat (greater than 2M) in place, must have good exhaust ventilation, make sure the battery is running loop mirror temperature 15-25 degrees. Making a longer battery life. ● charging current and voltage, the time specified by the manufacturer must perform, to avoid battery overcharge and over-discharge. ● complete model, price, reliable quality!
