Branch, battery voltage battery 12V120AH affect the reliability of the battery cell is a single "original battery", each of the original battery voltage of about 2 volts, primary batteries connected in series to form a high-voltage battery, a 12-volt battery from 6 composed of primary batteries, 24 volt battery from a primary battery 12 composed like. When the UPS battery charge, each primary batteries in series have been charged. Original battery performance will lead to some slightly different primary battery charging voltage is higher than other primary battery, the battery will advance this part of aging. As long as a certain concatenated primary battery performance, the performance of the entire cell will also decrease. Test proved battery life and the number of the original series the battery, the battery voltage is higher, the faster aging. UPS capacity is constant, the design should be as far as possible so that the battery voltage is low, so the longer the UPS battery life, battery voltage for a certain time, you should choose a small number of voltage primary battery cells in series, do not select the number of multi-voltage low primary batteries in series battery. Some manufacturers UPS's battery voltage is relatively high, because the capacity of a certain time, the higher the voltage, the less current, the wire can be chosen smaller and smaller power semiconductors, thereby reducing the cost of UPS. Capacity 1KVA UPS battery voltage so generally 24ˉ96V. Branch gfm Series Battery Features ● Maintenance-free professional design highly reliable professional VRLA design, effectively ensure that the battery does not leak (infiltration) liquid, mist-free, non-corrosive gases generated during charging substantially reduced electrolyte recovery when used without adding water, rehydration and electrolyte specific gravity measurements ● long life unique formula, effectively resist corrosion plates; high-current discharge characteristics, fast charging performance, deep discharge recovery capabilities, ensure that the battery life of the floating design life of up to 6 years (25 ℃) ● minimal self-discharge current of high-quality high-purity material, less than 4 percent of monthly self-discharge current, reducing battery maintenance work ● customers a very wide operating temperature range at -15 ℃ ~ + work under the temperature conditions of 40 ℃. battery resistance is less than conventional batteries. can be large current discharge ● reasonable installation and structural design using the latest international structure design, easy to install, easy to maintain ● Battery charging notice a stable standard charge voltage battery is not used for a long time should be all batteries are rechargeable adjust to more than 90% charge capacity of the battery should enter the float reaches maximum capacity Notes (1) non-professionals do not open the battery, avoid danger, such as accidentally ruptured battery case exposed to *, rinse with plenty of water, seek medical attention if necessary. (2) the use of multiple batteries, pay attention to the connection between the battery correctly, be careful not to short circuit. (3) the use of the process should avoid strong vibration or mechanical damage (4) the use of the upper and lower battery container with air vents for cooling. (5) Do not let the rain poured into the battery, or the battery is immersed in water for VRLA batteries, the charging method is best VRLA battery charge. Cleaning (6) battery with a try wrung damp cloth, do not use a dry cloth or duster, etc. Do not use chemical cleaners to clean the battery. (7) Do not mix different capacity and different old and new batteries of different manufacturers in the same box.
