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.Laptop battery Dell Laptop Battery

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.

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).Dell Inspiron 1501 Battery  Dell Inspiron E1505 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.

Tyco Electronics Group announced that its TDI battery company in Shanghai, Sony laptop battery Laptop Battery the first independent full-function battery and battery-specific testing center has been fully operational. Test Center will serve as the global TDI battery service center battery pack, battery,Sony laptop battery PCB power plant and other components of the research and development, quality assurance and safety testing.

TDI battery testing center so that the quality of the global testing and verification services to more than double capacity. Test Center area of more than 6,000 square feet, the battery environmental chamber configuration, the battery and the red battery discharge test circuit,Sony VGP-BPS3 Battery, Sony VGP-BPS5 Battery, Sony VGP-BPS8 Battery, Sony VGP-BPS9 Battery, as well as other specialized equipment,Sony VGP-BPS9 Battery, Sony VGP-BPS10 Battery, Sony PCG-R505 Battery, and set aside sufficient space for future expansion purposes.

New test equipment for the interior components and batteries certification, in particular, is a sealed battery, PCB and complete product assembly and design. Testing will be done through the internal, customer requirements and standards and specifications, the safety of products, failure, EMC, environmental reliability, electrical performance and service life, etc. Dell Inspiron 6400 Battery   and set the former standard test specifications.
TDI battery company in the world's well-established electronic,Sony VGP-BPS3 Battery, mechanical and chemical engineering design team focused on providing quality and cost-effective design, and the most cutting-edge design and manufacturing technology. Test Center Testing the independence of unique capabilities, will help large customers in the same testing center to complete all the necessary regulatory and environmental testing. In line with the company's flexible production methods, the extended battery so that TDI is able to continue to provide customers with a full set of complete power supply design.
he use and testing proved that the company's electric vehicles dedicated to the performance of sealed lead-acid battery has surpassed Japan to SBA S 8002-1996 "small lead-acid batteries used in electric vehicle standards" and the People's Republic of China machinery industry standards JB/T10262-2001 " Electric Bicycle standard sealed lead-acid batteries,

 

    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:

    (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.Compaq Presario CQ40 battery

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.
