How: 4ways to Test Battery Capacity on an Electrical Product

4 Ways to Test Battery Capacity on an Electrical ProductAs you look at the products you manufacture in China, you need to evaluate the risks that something goes wrong.When it comes to electrical products, one of the major risks is that the supplier uses substandard components in order to earn more profit.From experience, the risk is particularly high with batteries. The product might work fine during an open-the-box-and-turn-the-product-on inspection, but might have a very small capacity.There are basically 4 options to check the battery capacity in a final inspection.Option 1: off-site testAll electrical testing labs, It is one of the most basic testing devices.Typically, the inspector takes a few samples of batteries and sends them to the off-site testing place. After that, the tester needs to be set up, and it needs to be operated (for several cycles). The point of doing several cycles is to check that the batteries can actually be discharged and recharged, and to have a better idea of average capacity over time.Option 2: accelerated testingIdeally, all could be done on site, in the factory, without sending any batteries. But it takes a long time, often 8 hours or more. The inspector often needs to go back (catch the last bus, work on reporting, etc.)So, why not accelerate it? It would be easy, if not for a non-linear relationship because of internal heating (extra energy loss).If your supplier has a solid expertise about batteries, ask them what result can be expected if the test is expected to last no more than 5 hours. (Their regular tester can certainly do that.)Option 3: overtime at the factoryAnother simple solution is for the inspector to stay for longer in the factory (which incurs an extra fee for overtime).But how late? You can ask the supplier how long the test will last if not accelerated.Option 4: aborting the testThe inspector stays until the time he needs to leave, and records the reading on the tester. This is better than nothing.

To ensure the quality of audit.Audit procedures specify the specific steps that must be taken to achieve the objectives and not only make the audit accountable.People can keep abreast of the progress of audit work at any time and ensure that auditors do not neglect important audit steps and procedures.Major matters in order to ensure the quality of audit work from the perspective of audit procedures.2.

What are the characteristics of internal audit procedures?

I. The Characteristics of the Preparatory StageInternal audit carried out by internal audit institutions of departments and units is basically the same as national audit in the preparatory stage, but the basis for determining audit projects and formulating audit plans is more the actual economic situation of the departments and units, as well as the cases handed over by the leaders of the departments and units. Internal auditors are generally familiar with the internal situation of their departments and units, so they can quickly move to the implementation stage without much preparation. At the same time, because the internal auditors are members of the Department and the unit, the audit work programme can be more flexible and flexible, and can be amended at any time.II. Characteristics of the Implementation PhaseInternal audit should inform the auditee in advance, but it is not necessary to make a preliminary investigation, nor to conduct a sound investigation, conformity test and effectiveness evaluation of the internal control system. Auditors rely on their own understanding of their own departments and units, and have accumulated an understanding of the audit environment, which is generally enough to enable them to go straight to the beginning of the implementation stage to conduct in-depth audit and inspection work, and then some general conditions need to be understood, and can also be carried out in combination with audit and inspection work. Suggestions for improvement may be made to relevant units and personnel at any time for problems found in the audit.III. Characteristics of the Ending StageThe audit report of internal audit shall be submitted by the auditors who handle the internal audit, and the opinions of the auditees shall be solicited and submitted to the leadership of the Department and the unit for examination and approval. The approved audit opinions and audit decisions shall be served on the auditees. The auditee must implement the audit decision. Follow-up audits should be conducted on major projects to check the implementation of audit decisions after the adoption of audit opinions. If the auditees have objections to audit opinions and audit decisions, they may submit them to the head of the unit in which the internal audit institution is located. The head of the audit institution shall deal with them in a timely manner. Audit institutions accredited by the state audit institutions shall act as internal audit institutions of the departments accredited by the state audit institutions, and the audit reports made by them shall also be submitted to the accredited audit institutions.
