10. Output trigger method: The mainland pigeon tester has a self diagnostic and detection function for the battery. Under normal circumstances, a slight clicking sound should be heard when the repaired battery is connected to the tester, indicating that the internal relay of the tester is engaged. If the battery voltage is too low, connect the repair device and operate the corresponding functions such as starting repair. At this time, although the red digital tube on the panel displays normally. The digital display of charging and discharging flashes alternately, but there is no corresponding current and voltage output under the self protection detection function of the tester. In this case, a good battery with a voltage higher than 6V can be triggered and the positive and negative output lines can be quickly connected to the repaired battery. A simpler method is to prepare a 9V stacked battery (a commonly used battery in a multimeter that is easy to purchase) to trigger the tester output. Use the positive and negative terminals output by the tester to simultaneously contact the positive and negative terminals of the 9V stacked battery.

11. Cooling method: During the charging and repair process, the temperature of the battery casing should be checked frequently. When the overall temperature exceeds 40 degrees (feeling hot by touching with your hand), it is necessary to check whether the charging voltage and current are too high (the voltage and current of the mainland pigeon tester are very accurate). If they are normal, cooling treatment must be given. (1) Fan blowing cooling; (2) Immerse 2/3 of the battery in water to cool down without interrupting repair work (such as charging and discharging, sulfur removal, etc.); (3) Reduce charging current (such as shunting parallel batteries), extend charging time, etc.

12. Activation charging method: During storage or use, batteries can be regularly activated for charging, which is called balanced charging. This is very beneficial for preventing irreversible sulfation of batteries and is beneficial for battery life, and is worth promoting. The mainland pigeon battery capacity tester consists of three independent 12V circuits (36V type) and four independent 12V circuits (48V type). The output current and voltage are controlled by a microcomputer, making the output current and voltage very accurate and can be used as a balanced charger. Because the balance of series battery packs is common, there will always be lagging batteries during use. In general, using a tester to regularly charge, discharge, and charge the battery can achieve the goal of balanced charging.

13. Deep discharge and overcharging repair method: (Note: Suitable for voltage drop tester version during sulfur removal).

In repair practice, it was found that some batteries are stubborn diseases, with no short circuit or open circuit. However, regardless of multiple repairs and charging and discharging, they have no effect, and the test capacity is very small or even zero. The stubborn problems of such batteries can be repaired through deep discharge and overcharging. But deep discharge does not mean simple deep discharge, but rather skillfully using the potential function of the tester to immediately continue depolarization and sulfur removal after battery discharge, so that while deep sulfur removal is carried out, deep discharge is applied to the battery, causing the battery voltage to continue to decrease (using the tester to run repair function, the battery voltage naturally decreases slightly) to at least 9.5V below. It is best to achieve better results below 7.5V. Then charge to 16.2V (note: when the voltage exceeds 14.8V, the battery pressure limiting rubber valve must be manually opened or unplugged to prevent the battery from overcharging and causing deformation of the casing).
