US SORENSEN battery 12V100AH_SAL series American SORENSEN battery 12V100AH ??detailed description: SORENSEN battery high practical advantages: lower float design application mode battery life of more than 10 years. Advanced Pb - Sn - Ca - Ag alloy anode, help prevent corrosion of the high pressure valve, greatly increasing the battery internal gas recombination rate (more than 99% at 25 ℃) the unique positive grid expansion capacity, is greatly reduced the possibility of a short circuit bending and vertical plates can be equipped with additional carrying handle, easy to install and transport. All Dorset batteries are manufactured under strict ISO9000 quality control system, the factory 100% quality inspection, 24-hour service. Technical support services provided by the company: The company provides technical services including telephone support and on-site support two, to assist the user equipment failure timely to be resolved to ensure that equipment is reliable, stable operation. A telephone support service A, the user during maintenance, equipment failure occurs due to technical causes, which led to not work, the service request may be made to the Company by telephone. B, maintenance engineers telephone support team with the fastest time in response to user service requirements, to answer questions raised by users, user assistance and guidance to develop solutions. 2, on-site support services A, in the case of telephone support can not properly resolve the problem within 48 hours we will send technical personnel to the scene to help users troubleshoot. B, for the product during the warranty period, the warranty period, we will replace free of charge due to technical problems of raw materials, design and manufacturing processes and quality issues and the failure of the product, and the buyer can not deal with the main issues, free provide replacement service and timely solutions to the problems existing in the product and product repair problems. C, for product warranty expires, upon the buyer's request we provide for any faulty equipment maintenance services, repair bad product in a timely manner to the best price replacement. When replacing the battery should pay attention to what? Replace the battery check feature is the use of reverse diode artificially make old battery (GB, GB ') between the voltage difference, the new battery GB' input, when the old battery GB exit from the diode as an electronic switch instantaneous power to the DC bus, thus avoiding the old battery pack voltage is generated due to the difference in the parallel process of circulation, to ensure the stability of the DC power supply. While avoiding the UPS battery battery pack battery-powered process without interruption due to the DC bus DC bus replacement power supply box, which may cause the DC system unreliable factor. The methods are: 1, 2 # U charger stops running, remove the UPS battery GB 'in series fuse FU. 2. A fuse in FU5 ends, C point and connect the diode V (2CZ 200A / 800V). 3, check the wiring is correct evacuation battery fuse FU. 4. Remove the fuse FU5, V diode string to the circuit, together SA3, check for -WOM cathode of the diode voltage of about 241V, for -WOM anode voltage of about 218V, reverse blocking diode. DC bus by the charging machine 1 # U, battery GB, GB 'parallel power supply, but the battery GB' low voltage DC load by Charger 1 # U, GB battery power. 5. Disconnect SA1, remove the fuse FU3, FU4. Batteries GB 'V power supply via a diode to the DC bus instantly. 6, start charging machine 2 # U, and rated voltage to DC bus by the charging machine 2 # U, battery GB 'parallel power supply. 7, remove the old battery from the battery panel group GB, and in the immediate vicinity of the DC panel connection number, which is the positive and negative leads, respectively charger 1 # U of positive and negative corresponding connection. 8. Start charger 1 # U, so that voltage and assembly of old batteries in parallel for after 241V. 9, disable the charger 2 # U, battery GB 'short voltage down to about 235V. 10, co-SA1, charger 1 # U, old batteries GB, the new battery G B 'parallel power to the DC bus, but the charger voltage 1 # U GB in parallel with the old battery is higher than after the new battery GB 'voltage, the load current from the charger 1 # U and old GB battery-powered, but V reverse blocking diode, not to the new battery GB' reverse charging. 11. Disconnect SA3, the new battery GB 'dismantle the battery installed to screen. 12, and will be connected to both ends of the fuse FU5 V diode connected to both ends of the fuse FU3. 13, mounted fuse FU4, charger 1 # U, old and new batteries in parallel to the DC bus, because the diode V role, charger 1 # U, the old battery to the DC bus power supply only, not to the new anti batteries charging. 14. Disconnect SA1, the new battery-powered UPS via a diode V to the DC bus. 15, mounted fuse FU3, V diode is shorted. At this diode V has been out of action, should be charged removed. 16, remove the old battery. 17, co-SA1, charger 1 # U with a new battery pack, parallel to the DC bus.
