BaseBuild Battery From the current situation, widespread decline in battery capacity too fast, short-life issues, just 1 to 2 years battery capacity of only a nominal capacity of 30% to 40%, some only 10% to 20% , and most of the base station battery after a 4 years running, Hp laptop battery its capacity is only 50% of its nominal capacity of about fall far short of its design life, and ExchangeBureau stations compared to similar batteries, their life is also greatly reduced. In this paper, the base station Damage to the battery during the operation carried out an analysis of the reasons put forward to extend the battery life of the base station approach. HP Laptop Battery TOSHIBA Laptop Battery First, the definition of battery life Battery life generally refers to floating state of life. For the non-floating mode of operation of the battery, its life cycle of discharge from the number and depth of discharge measured in two dimensions, as shown in Table 1. It is not simply in order to be able to use for many years to measure battery life. For the number of battery discharge cycles, the battery must be sufficient after discharge electricity, enough power to at least 24 hours charging time (based on YD/T799-2002 requirements). For the charge is insufficient, its difficult to determine the number of discharge cycles, will certainly be lower than the data described in Table 1.Dell Laptop Battery Depth of discharge of the battery life impact is very large, the deeper the depth of battery discharge, the fewer the number of recycling, as shown in Table 1, and therefore should avoid the use of depth of discharge. Second, battery end of life factorsLaptop BatteryACER Laptop Battery For valve-regulated lead-acid batteries, there are four kinds of failure modes: positive plate corrosion,HP 398876-001 Battery, water loss, thermal runaway, sulfate. One positive grid corrosion due to alloy Improvement in the corrosion rate is very slow, generally 10 to 15 years. Water loss are more ways: throttle design unreasonable, frequently open; the power of the batteries are rechargeable frequently; the ambient temperature is too high. Which is the most important factor in high-temperature, high temperature will accelerate the pace of battery water loss, leading to decreased battery capacity. With 25 ? as the benchmark, when the battery operating environment up 10 ?, life expectancy reduced by 50%, as shown in Figure 1.
