In our examinations we usually gathered "large" batteries with a capacity of 60 a⋅h for European cars. We have now examined a narrow batteries of different capacity for Japanese and Korean cars.
Accumulatory examinations of recent years have been collected by participants with the same declared capacity, for example, 60 A. hours However, it is known that the amper-hour marking on the label is not the most important parameter. The manufacturer of the ACB, for example, 58 or 62 A, has always passed the tests where we took only "sixty". This is why, when we fail to test the batteries of the "eastern" type, we are oriented on the dimensions: if the battery comes to its place and has "the right" conclusions, it will suit the car. Set "gate": 238 x 129 × 227 mm (which is a small amount of battery bay of Japanese and Korean machines) and purchase all batteries that will be held in them. We got 15 of them on the battery. Therefore, we are waiting for the "spots"! Move the batteries around the playing field after each of the five valid tests. Before the test series starts, charge all batteries: traders do not. It is suggested that we look closely at our final table, which shows the backup capacity of the batteries at the time of purchase. Almost all the batteries were defused at forty percent. All right, start the tests: the chips on the playing field come in motion!LESSES AND RESULTS. It shows how long a cold rainy night will hold the car that crashed the generator. The engineer will be more precise: for the number of minutes the voltage on the terminals of the 25 A current battery will be reduced to 10.5 V. The measurements shall be made at a temperature of 25 ° C. The higher the result, the better. The best result is Medalist: 84 minutes. The given intake energy. Characterize the power of the battery in a starting mode. The inspection shall be carried out at -18 ° C. At first, the battery is discharged with the declared current of the cold scroll Ich for 30 s and the voltage of U30 is recorded on its output. After a 20-per-cent pause, the battery is discharged with a current of 60 per cent of the declared Ihp until the voltage is reduced to 6.0 V. The t6 bit is written. The given launch energy is calculated using the formula: E = 0.3Ich (U30-6, 0) t6The higher the total, the better. The best result is Medalist: 26.19 kJ. The given intake energy is a single current. Compare the current values of all batteries under the same conditions, regardless of passport data. The inspection shall be carried out at -18 ° C. At first, the battery is discharged with a current of 300 A for 30 s and the voltage of U30 on its pole conclusion shall be recorded. After a pause of 20 seconds, the battery will discharge a 180 A current until the voltage is reduced to 6.0 V. The t6 bit is written. The given launch energy is calculated using the formula: E = 90 (U30-6, 0) t6The higher the result, the better. The best result is Medalist: 47.25 kJ. Pusher properties at 50%. The starting characteristics of the battery are assessed, half discharged, for example, after driving in traffic with a large number of energy consumers. The battery shall first be discharged with a nominal current of 10 hours. Then at 0 ° C, it is fully cycled 300 A for 10 seconds with a duration of 30 seconds. Record the number of attempts in which the battery provides more than 6.0 V voltage, and the length (in seconds) of the last, incomplete attempt at which the voltage is less than the specified voltage. The more result, the more natural it is. The best result is Panasonic: three launches and 6 s. Recovering from the full line. Simulate a situation caused by a complete discharge of the battery (forgot to turn off the headlamps, etc. ). The battery is discharged to voltage on the terminals of 2.0 V and held for two days, then recharging and evaluating the reserve capacity. The more it is, the better. The best result is Medalist: 85 minutes. GDE PROMURALY AND CAVERS SARVNIIMALL battery samples for expertise acquired in large stores of the retail chain. The measurements were carried out by the specialists of the Institute of Scientific Research and Scientific Research Institute of the Russian Defense Ministry. The data obtained refer to a particular sample of batteries and are not absolute criteria for their quality. According to the results of the measurements recorded in the report, the best and worst indicators were taken in each type of test, giving them 5 points and 1 point, respectively. All other participants received intermediate points according to the position they had taken between the leader and the outsider. For example, if the leader showed 84 minutes of the backup capacity, and the outsider was 68 minutes, the participant received 2.25 points with the result of 73 minutes. And all five kinds of tests. The final score is the arithmetic mean of five intermediate evaluations. We did not become equal to the weight values that increase the importance of one parameter relative to the other. At the same time, the figures we have given allow anyone who wishes to have their own calculations. It is clear that the placement of seats will necessarily change. MORE DETAILS!The gaming field is full: 15 batteries are lined up. Note that their price (scatter almost three times) did not guarantee expensive products in the first row. Yes, the road "Panasonic" became the second, but at the same time the cheap seal battery was the fourth, not the last. On the whole, the tiny batteries pleased: a huge supply of energy in such a modest size pleased. But notice that working at -30 ° C they all ... refused! Or rather, they were given away, but so grudally, that this stage of the tests should be called 'Who's Worse? '. No standards are provided for such degrees, but the owners of the relevant vehicles must be morally ready for such trouble. The table opens to the full size of the click. Explicit leaders-medalist and Panasonic, from domestic sources Tyn Asia, Tumen battery, and AKTEX. And those who are interested in the stability of results are like the three of our prize-winners of the past: 2010: medalist, VARTA, "Beast" 2009: VARTA, medalist, A-Mega 2008: Bosch, Medalist, VARTA 2007: Mutlu, ACOM, M. Aliliston all the launches and the happy journey!
