ups电池维护（UPS battery maintenance） Use and maintenance of UPS batteries -------------------------------------------------------------------------------- 1. overview The types of batteries are generally divided into lead-acid batteries, lead-acid free maintenance batteries and nickel cadmium batteries Lead acid battery General type battery, also known as the water battery maintenance life expectancy 1~3 charge and discharge will produce hydrogen cars, the site must set the exhaust pipe so as to avoid the danger of electrolyte is acidic, metal corrosion will often need to maintain low prices of water free lead-acid battery maintenance free battery. The new battery without adding water of life expectancy is generally 5~7 years sealed charge does not produce any harmful gas equipment easily, without considering the location problem of ventilation, maintenance free, maintenance free discharge rate is high, stable characteristics high price of nickel cadmium battery. Special occasions and special equipment on the water of life expectancy 20~40 water as the medium for advanced battery, charge and discharge will not produce harmful gas loss rate is low, but need to fixed time and maintenance water discharge characteristics of the best can be placed on any harsh environment high price of UPS considering the load conditions, the use of the environment, service life and cost factors, general select the lead-acid battery maintenance free battery. 1) what is the concept of the number of ah battery The size of the battery capacity number ah. The battery rated capacity to 25 DEG C, with a constant current discharge for 20 hours until the voltage (1.75V/ cells), which is 20 times the current capacity of the battery, the battery charge and discharge current in C to say, the actual value of the battery capacity associated with C. For example, if its 100AHs battery: 1C = 100A. Cn indicates 20 hour discharge rate. Some batteries are calculated at 10 h discharge rate, expressed in C10. Ex
