Thermal runaway is the battery in charging the heat generated in the process is not released in time, temperature and chemical reactions between the formation of a positive feedback gets out of control. Thermal runaway of the battery is devastating, resulting in battery case deformation caused serious battery explosion. Thermal runaway because the room the ambient temperature exceeds 45 ℃, high temperature float voltage is too high (without temperature compensation), the charge current exceeds the design value (more than 2.5C10).Toshiba pa3399u-1brs battery TOSHIBA PA3399U-2BAS Battery
Sulfate is generated in a very white-board hard lead sulfate crystals, particle relatively large, active low,HP PB992A Battery, charging hard to get into lead sulphate as active substances, resulting in battery capacity decline or failure. Hydrochloride of the reason is that the battery in the installation set aside a long time before storage (more than 3 months), persistent or recurrent excessive discharge excessive discharge or a small current deep discharge, the ambient temperature is too high or too low, often inadequate and does not charge a regular basis are sufficient.
Years, four million mobile phone battery scrap the proposed processing center in Chengdu, "detoxification"
Recently, the reporter learned from the Municipal Environmental Protection Bureau, Chengdu,Laptop Battery
the proposed hazardous waste processing center has recently been
selected owners of units are currently located. The cooperation between
Chengdu and the Changhong Group, Waste Electrical Treatment Center has
recently initiated negotiations, the project most likely settled in
Jintang County Huai River Town. By then, most parts of Sichuan, Chengdu,
as well as waste electrical and electronic products, there will be
disposal of the Department.
Annual waste of about 4 million mobile phone batteries
"Also for mobile phone batteries, this battery waste, together with the ordinary rubbish put fear, let alone throw them powerless place, you should pay attention to the media about the whole thing." Recently, Chengdu Jinjiang District near the East than the field of property management of a residential area Members complained to reporters that an increasing number of electrical and electronic waste, the do not know what to do. TOSHIBA PA3421U-1BRS Battery TOSHIBA
Reporters in the East than the field, off the Hongqiao, four visits to shrines such as found in the streets, the residents do not know how to dispose of mobile phone batteries.Toshiba Laptop Battery In the four shrines plum garden district security, said the plot in 2008 prior to installation of dry battery recycling recycling bins provided. But in fact recovery of batteries is now being done is no longer handled.
It is understood that a cell phone battery pollution load equivalent to 100 ordinary dry batteries can be seriously contaminated by about 60 million liters of water, equivalent to an individual's life and the amount of drinking water. The popularity of mobile phones according to 70% of the amount of calculation, Chengdu, there are about 8 million mobile phones, if a battery replacement every two years, then every year about four million mobile phone batteries obsolete. Provincial Environmental Protection Office, who introduced similar to the discarded cell phone batteries, usually requiring that the manufacturer recall. The question now is, few people would surrender their waste battery manufacturer, PA3456U-1BRS Battery or do not know how to return the factory.
Third, the impact factor in the base station battery operating life
Remote location of many of the base station, AC power supply instability or frequent power outages, or even simply do not alternating current; no air conditioning or outdoor base station sites, the ambient temperature is high; site, remote and quantity, can not be refined to maintain. These are the base station battery working conditions of the environment.
China's base station batteries through the analysis of the damage, collecting Xinjiang, Zhejiang, Shaanxi and Yunnan provinces battery damaged specimens analyzed in conjunction with overseas Vietnamese, Egypt, Pakistan, Ethiopia, the base station power can corrupt data, we have come to affect the operational life of battery There are the following factors:TOSHIBA Pa3356u-1brs battery
(1) AC frequent power cuts
Frequent power outages, power outages a long time, outage time irregular, so that frequent battery charge and discharge, or the base station simply do not alternating current, through the turn of diesel generators and battery power, is caused by rapid decline in battery capacity and shorten the life of a major reasons.
The base station blackout frequency is too high, power outages several times a day, or even power outages for several days straight, so that the base station after the battery discharge fully charged yet another case of discharge, battery charging time is owed to the state. As has occurred many times due to continuous charging, HP PB994A Battery, battery capacity will result in cumulative losses, sulfate of aggravated battery capacity will decrease in a relatively short period of time, its life will be quickly terminated.

(2) The battery is stored too long
Exist in the process in the storage battery self-discharge, if the time is not added, there will be the phenomenon of sulfate. If this is the absence of timely improved battery capacity would be reduced or even damage can not be used. Battery in the storage process, the ambient temperature also has great influence on the capacity, as shown in table 2.
