Electric Bicycle Batteries

To safeguard the legitimate rights and interests of consumers, promote sealed lead-acid digital camera battery electric bicycle industry, healthy development of the Tianjin Bureau of Quality Supervision Organization sealed lead-acid battery electric bicycle product quality supervision checks. A total of 19 random distribution unit sales of 19 manufacturers produce 19 batches of products, results showed that: 16 batches of qualified, unqualified three batches, the product sample pass rate of 84.2%.

Spot checks found in the main quality issues:

First, the rate of capacity of individual products, two hours failed. 2 hours and the rate of the battery capacity is the key performance indicators, reflecting the batteries in normal use of the discharge time. Discharge time is short, then the electric car is also traveling a short distance. Standards require that electric bikes sealed lead-acid battery 2 hours the rate of capacity should be ≥ 100%. There are individual product sampling rate of 2 hours for 82% of capacity kodak klic-5001, up to standard requirements.

Second, low-temperature capacity of some of the products failed. Low-capacity related to the battery at low temperature environment using performance determines the condition of the battery used in the winter cold effects. There are three sample batches of low-temperature performance of substandard products, of which a minimum capacity of only 28.6% of rated capacity. The battery acid is mainly within the high density, viscosity increase, resulting in lower emissions of the battery.

The poor quality spot checks are: Nominal Power Co., Ltd. is appropriate Singshih the revitalization of the production of “Eagle” brand 6-DZM-14 Electric bikes sealed lead-acid battery, its capacity, low-temperature performance, two indicators of failure ; nominal kit for the Zhejiang Changxing Power Co., Ltd. can produce “special” brand 6-DZM-14-type sealed lead-acid kodak klic-7001 batteries for electric bikes. Its capacity, low-temperature performance, two indicators of failure.

For the sample reflected the major quality problems, Tianjin Bureau of Quality Supervision in accordance with the Product Quality Law and other relevant laws and regulations, product quality spot checks of enterprises according to the law failed to address and a deadline for correction. At the same time, will continue to track the quality of the products samples to promote electric bikes sealed lead-acid battery industry as a whole level of quality continues to improve, and create confidence for consumers satisfied with the consumer environment with kodak klic-7004.
