Pace direct superior official website of UPS batteries under normal use, maintenance hosts rarely, mostly dirt and dust regularly. Especially dry climate regions, more dust particles in the air, fans will be inside the deposition of dust into the machine, when the case of moist air will cause the host to control disorder caused by a host of work disorders, and the occurrence of inaccurate warning, a large number of Dust can also cause poor cooling devices. General should be thoroughly cleaned once every quarter. The second is when the dust, and inspection of all fittings and connectors for loose and contact is not strong. Storage battery maintenance-free batteries are currently using, but only eliminates the previous measure than the ratio, the timing of the work to add distilled water. But the impact of external factors on the working status of the battery does not change, does not affect the normal operation of the battery caused no change in this part of the maintenance and overhaul work is still very important to a lot of maintenance repair work UPS battery power system, mainly in parts of the reservoir all the work cell is in a floating state, in this case should be conducted at least once a year discharge. Discharge the battery pack should be preceded by a balanced charge, in order to achieve a balanced whole set of batteries. To clear behind the battery before discharging the battery pack that already exists. If the discharge process to reach a discharge voltage, discharge should stop, continue to discharge the battery and then put behind the first elimination. Check the discharge, not the pursuit of what percentage of the release of the first volume, but to focus on the discovery and processing behind the battery, the battery handle backward after discharge experiments for verification. This prevents accidents, in order to avoid discharging the battery behind the deterioration of reverse polarity battery excellent professional and excellent Pace Pace YUPPLES battery UPS battery, excellent battery DC panel Pace, Pace solar excellent, excellent communication system battery power Pace, YUPPLES batteries and other electronic equipment. MF65-12 Rated voltage: 12V Rated capacity: 65Ah Dimensions: 349 * 166 * 174 ± 2mm at 25 ℃ (77 ℉) resistance when fully charged: Approx 6.4mΩ charging method (constant voltage) cycles: the maximum charging current 16.25A charging voltage 14.5-14.9V / 12V77 ℉ (25 ℃) temperature compensated charging voltage is -24mV / ℃ Float: The maximum charging current for charging voltage 16.25A 13.6-13.8V / 12V77 ℉ (25 ℃) temperature compensated charging voltage - 18mV / ℃ 【Application】 solar garden lighting l l l small home solar street lighting system, solar outdoor lighting l l advertising for a variety of low-power appliances, emergency lights Yeah, advertising lights, traffic lights, household lights, fans, For example, solar water pumps, solar lights, small solar systems [Description] 1) installation, use and maintenance process, not short-circuit the battery, not inverted position, use insulated tools, and equipped with insulated gloves to prevent electrical shock and cause a short circuit . 2) When the battery is abnormal, treatment should be professionals or contact the manufacturer to prohibit dismantle repair. 3) The product should be charged on a dedicated charging system, charging system, the DC output voltage fluctuation should not exceed plus or minus one percent. 4) prohibit the use of gasoline, thinner or other organic solvents to clean the battery, otherwise it will damage the battery casing. 5) prolonged excessive charging (overcharging) will shorten battery life; charging time is too low (not enough) will affect the load of work or cause abnormal voltage. Charging the best charger with constant current limiting. Do parallel charging, otherwise shorten battery life. When the charge must first charger positive (red) and negative (black) battery charging clip corresponding good clip, do not reverse. After charging, turn off the power switch, and then take the battery holder.
