How to test backup battery internal resistance
Battery internal resistance many different types of test equipment, their main difference between testing different types of batteries to test the capacity and the battery terminal voltage is different, and here I say was for electricity, telecommunications and UPS power supply battery testing and laptop battery test
Preparatory work before the test
1, to the tester is fully charged, check the tester is working correctly
2, prepare some necessary maintenance tools and personal protective equipment, such as insulation fastening tool
3, view the history of the battery being tested may be many units do not have the record, even when the PA3191U-1BAS battery is installed into use are not clear, but you must do some homework and find out it
4 in preparation for a number of self-adhesive labels, conditional on the label marked with models, internal resistance, test date, label
5, bring a thermometer to record the ambient temperature test, with thermometer, we must bring
6, to prepare a record book, record the test a number of unforeseen circumstances and experiences
Test Frequency:
In fact the cycle of bad batteries are weeks as a unit, in other words the performance of battery mutation is completed within 14 days, from this feature is concerned, we should be done once a week resistance testing, but the electricity and telecommunications industry, such work intensity can not be achieved, I recommend testing at least once every quarter, the United States to maintain such a standard is required, the minimum should also be a year of testing on critical systems, does not allow any power outages the unit, I recommend the use of On-line detection system.
Some engineers argue with me our Board order for so many years had not been implemented, nor out of any major incident, I told him, not when there is no PA3383U-1BRS battery power, are bound to occur associated major fire accident, or the burning main transformer, but this situation will continue, a major accident. This is a logical problem, I would not have discussed.
Test is prone to problems
Test Steps
1, reserve equipment
2, check the IBM laptop battery surface temperature, check the battery is a good idea to touch the battery temperature to prevent an explosion in testing accident when conditions permit, a friend can use the infrared thermometer and a thermal imager to detect the temperature.
3, sorted by battery test, an exception occurs when the internal resistance, it is necessary to connect the same time, resistance testing, if necessary, tighten and re-test
When the charging system, the ripple is too large, it can temporarily turn off inverter module carrying out tests
4, store test results
5, analysis of test results
7, in the self-adhesive label and marked
8, print test reports and archive
Several theories Mistakes
1, on the standard value problem
Apple laptop battery does not correspond to the standard and capacity within the resistance, we compare changes in the benchmark test is the initial value, and many of the industry boss spent a lot of time to verify the standard is meaningless within the resistance, the United States after 1996 are no longer further discuss this issue.
2, with regard to the problem of inaccurate test results
Testing is not an accurate only to a good sub-contractors into a bad battery and A1060 battery, sentenced to a bad battery into a good battery, this happens for the following reasons:
Charge state compensation with useless equipment testing the constraints of inadequate recharge the battery, and then filled with 25 ° under the internal resistance to compare the charge, the battery internal resistance as the reduction in battery capacity increased into the 80 % capacity when the resistance will increase more than doubled, with the capacity to compare the inner resistance will naturally be an error in the conclusions of the
Test Equipment Test the value of large deviations, even though different test equipment section of the test instrument on the same test Asus laptop battery test results will be slightly different, but if the tester if the measured deviation large, the performance of your equipment problems , you have to be replaced.
3, on the different devices the test resistance is not the same problems
The same principle of resistance tester instrument measured a few micro-Europe, there are some differences, but will not affect the state of technology to judge the conclusions,
4, discharge capacity and internal resistance of nuclear testing that good
How to choose battery internal resistance tester
Now on the market supply of resistance tester variety, price from tens of dollars to several thousands dollars, be particularly careful when shopping,
Trial time to focus on measuring consistency, temperature drift and anti-jamming capability, otherwise your device is deaf ears.
Consistency test, that is, a row of a A42-A2 battery test times, test if the inner resistance and proximity, that is, consistency is good, the testing process, we must change the location of test probe clamp, and then read the results
Drift; Tester in just getting on plane measured results and start half an hour after the test results and a uniform requirement, and the difference of a few micro-ohms
Anti-jamming capability that is connected A42-W3 battery charging module and disconnect the charger module measured data should have been.
