Shanxi most of substandard lithium batteries
Wednesday, November 4th, 2009The first quarter of this year, Shaanxi Province marketable quality and technical supervision bureaus of the battery product quality spot checks showed that most of substandard lithium batteries. The extraction of the original 19 batches of cells, with a pass rate of 73.7%. Quality problems are the main signs and the minimum discharge time of failure.
The sampling lithium battery 18 batches, with a pass rate was only 44.4%. The main problem is that there is the quality mark, 0.2C5A discharge performance, 1C5A-discharge performance, and the free fall the project failed. Failure showed marked signs incomplete information. 0.2C5A discharge performance and discharge performance of battery capacity 1C5A key indicators, which failed in the performance of the measured value is less than the standard value. Free fall is mainly assessment products in the transport and use of product and the external structure of the solid nature of the stability of charge-discharge performance.
Free fall drop test for the performance of the project failed after the battery discharge performance. Experts advise, lithium batteries can continuously charge and discharge of about 500 or so, should try to avoid all the batteries I put End rechargeable power, or with the increase in number of charge cycles, battery performance will gradually weaken, the battery standby time also will decline; In addition, the battery afraid of the cold Heat intolerance, dog day day, do not put a mobile phone under the sun to withstand sun exposure, do not get the air-conditioned room on the air blowing straight places.
