VRLA battery is composed of a positive electrode plate, a negative plate, AGM separator, sulfuric acid electrolyte, safety valves, batteries and other components and the battery cover. It has the following main features: corrosion-resistant lead-calcium-tin multi-alloy high-rate discharge very excellent self-discharge rate is very low fine glass fiber separator aspiration no harmful gasses from escaping excellent low temperature properties of high strength ABS resin shell and equipment installation will not pollute the environment with the Department Sealed no leakage without adding water valve automatically opened and closed for Free build battery room two, lead-acid batteries using 12V series battery float float voltage per cell 13.50-13.80V ± 0.02 (25 ℃), are charging pressure per unit Georgia 14.10-14.40V, this float voltage with the ambient temperature by 3mv / ℃ lower. 2V series battery float voltage per cell 2.23-2.27V ± 0.02 (25 ℃), charge voltage per cell 2.35-2.40V, this float voltage with the ambient temperature by 3mv / ℃ lower. Recycle 12V series battery charging voltage to each of the largest ever single cell 14.4-14.70V, the recommended initial charging current current rated capacity of 0.1 to 0.2 (A). 0.006CA when the current drops below three hours unchanged and stable, can be put into normal use. 2V series battery charging voltage to each of the largest ever single cell 2.35V, the recommended initial charging current current rated capacity of 0.1 to 0.2 (A). 0.006CA when the current drops below three hours unchanged and stable, can be put into normal use. Third, installation, use precautions GFM VRLA batteries should be placed in ventilated, dry place away from heat and sparking easy, safe distance of 0.5 meters. The availability of long life 25 ℃ temperature environment, long run if the temperature rise 10 ℃, life expectancy was reduced by approximately half. Within a temperature range of 25 ℃ -0 ℃ if each drop 1 ℃, the discharge capacity decreased by about 1%. Note that the battery polarity when installing the positive battery positive then charging the device or load, battery charging equipment or the negative pole negative load prohibited reversed. Since the voltage of the battery pack is relatively high, the installation, use and maintenance process should wear gloves edge, to prevent electric shock. Different models, different types and different battery newness can not string, and together. Battery pack before connecting with a fine wire brush to clean the oxide film on the terminal block, making it appear metallic luster, the battery pack must be securely connected at each connection, bolt and nut torque is about 11 Nm. When handling batteries should be at a normal position, should not be subject to severe vibration and shock. Note that when you install do not touch the terminals, the terminals must not allow short circuit, non-hanging terminals handling, so as not to affect the sealing performance. Charging the battery is factory finished, there are varying degrees of damage from the factory to the installed capacity between use, should be a reply before use charge. For a longer battery life, good performance, use automatic voltage limiting the charging device. When the load in the normal range, charging equipment should reach ± ??1% voltage precision, charging equipment should be able to meet the charging requirements of this specification requirements. Do not stop working during non-floating float use. Non-discharge, the process of using every single cell voltage generally not less than the factory standard or less. We must adopt advanced constant voltage charging, the charging voltage limiting device. Fourth, maintenance and Note: the battery is used for a period of time, should be carried out to determine the battery discharge test online capacity. Once a year to check for the actual load discharge test, the release of 30% -60% of the rated capacity. Every three years to do a capacity test shall annually for six years after use. 1, the battery is put into operation, the float voltage measured weekly, and make the following records: (1) Each single battery float voltage (2) The total battery voltage (3) The ambient temperature for 2, a proven track record in time Elimination of battery charging, maintenance or environmental aspects of the adverse effects caused by batteries, battery failure to provide the basis for the exclusion. 3, regular (1-2 times a year) to check strap is loose, if there is loosening, should be tightened. 4, can not use the battery in a sealed container. 5, after use of scrap batteries should not be thrown away, please contact the manufacturer for regeneration and recycling.
