Although maintenance-free batteries do not need to manually when using special maintenance work, but when you use or have certain requirements, if used improperly can affect battery life. Factors affecting the battery life are the following: The installation, temperature, charge and discharge current, charging voltage, depth of discharge and long-term charge and the like. 1) The battery Install the battery should be installed as far as possible in a clean, cool, ventilated, dry place, and to avoid sunlight, heaters or other radiant heat source of influence. The battery should be placed upright, not tilted angle. Between each battery terminal connections firmly. 2) Ambient Temperature Ambient temperature greater impact on the battery, the ambient temperature is too high, the battery will overcharge produce gas, the ambient temperature is too low, the battery will charge less, this will affect battery life. So generally require ambient temperature at about 25 ℃, Hills UPS float voltage value is set Click to temperature. 3) the charging and discharging current of the battery charge and discharge current is generally represented in C, the actual value of C is related to the capacity of the battery. For example speaking, if it is 100AH ??battery: C = 100A. Panasonic lead-acid maintenance-free battery charging current is about the best 0.1C, the charging current must not exceed 0.3C. The charging current is too large or too small will affect the battery life. Discharge current general requirements in 0.05 ~ 3C, UPS in normal use can meet this requirement, but also to prevent the occurrence of unforeseen circumstances, such as a battery short circuit. 4) UPS batteries are charging voltage due to alternate ways of working, under normal circumstances, electricity is charging only when power outages will discharge. To extend battery life, Hills UPS charger generally use constant current limiting control mode, the battery is fully converted to float state after each festival float voltage is set to about 13.7V. If the charging voltage is too high will cause the battery overcharge, otherwise the battery will charge less. Charging voltage is abnormal, it may be a configuration error caused by a battery or charger failure caused due, so when installing the battery, be sure to pay attention to the size and number of batteries correctness, different specifications, different batches of batteries do not mix. Do not use inferior charger plus charger, but also to consider the heat problem during installation. Depth on the battery life of 5) discharge depth of discharge is also very large, battery discharge the deeper, less its cycle times, and therefore should be used to avoid deep discharge. While Hills UPS has a battery low protection, generally single battery discharges to about 10.5V, UPS will automatically shut down, but the situation discharge light load or no-load discharge if the UPS is in, can also cause deep battery discharge . 6) regular maintenance battery after a certain time should be checked regularly, as observed its appearance is abnormal, measure the voltage of each battery is average and so on; if not long-term power outage, the battery will always be in a state of charge of the battery so that the activity will deteriorate Therefore, even without power, UPS also require periodic battery discharge test in order to remain active. Discharge test is generally three months time, the practice is UPS load - preferably at least 50%, and then disconnect the mains, so that UPS is in battery discharge status, discharge duration depending on the battery capacity is generally speaking a few minutes to tens of minutes to restore electricity supply, continue to charge the battery after discharge. Check the battery set is also recommended to use Panasonic lead-acid battery maintenance-free battery or other brand of high quality maintenance-free battery. Users do not choose to use inferior because of freeloaders batteries will self-discharge phenomenon (SELF-D1SCHARGE), if the long-term placement, will lose energy, thus the need to regularly charge and discharge. Engineers can measure the open circuit voltage of the battery to determine if the battery is good or bad, with 12V battery, for example, if the open circuit voltage is higher than 12.5V, it indicates that there are more than 80% battery energy storage, if the open circuit voltage is lower than 12.5V, you should immediately supplement charge, if the open circuit voltage is less than 12V, the battery is stored electrical energy is less than 20% of the battery unusable in danger. As a result of maintenance-free battery electrolyte absorption systems, in normal use does not produce any gas, but if the user used improperly, causing the battery overcharge, it will produce a gas, then the pressure will increase the battery, the battery will pressure valve on the top open, serious cause battery Guzhang, deformation, leakage or rupture, these phenomena can be judged from the appearance, such as found in the above situation should immediately replace the batteries. 3. Although the use and maintenance free batteries do not need to manually when using special maintenance work, but when you use or have certain requirements, if used improperly can affect battery life. Factors affecting the battery life are the following: The installation, temperature, charge and discharge current, charging voltage, depth of discharge and long-term charge and the like. 1) The battery Install the battery should be installed as far as possible in a clean, cool, ventilated, dry place, and to avoid sunlight, heaters or other radiant heat source of influence.

Between each battery terminal connections firmly. 2) Ambient Temperature Ambient temperature greater impact on the battery, the ambient temperature is too high, the battery will overcharge produce gas, the ambient temperature is too low, the battery will charge less, this will affect battery life. So generally require ambient temperature at about 25 ℃, Hills UPS float voltage value is set Click to temperature. 3) the charging and discharging current of the battery charge and discharge current is generally represented in C, the actual value of C is related to the capacity of the battery. For example speaking, if it is 100AH ??battery: C = 100A. Panasonic lead-acid maintenance-free battery charging current is about the best 0.1C, the charging current must not exceed 0.3C.
