1. Battery series repair method. This method is used when the nominal voltage of a single cell is lower than 12V. For example, rechargeable emergency lights on the market often use 6V4Ah batteries. The single-channel output of the tester is 12V. At this time, two 6V batteries can be connected to the tester for desulfurization repair (Note: The battery’s nominal capacity and appropriate charge and discharge current should be selected).
2. Battery parallel shunt method. If the battery temperature rises rapidly during the repair process. Charge and discharge should be reduced. At this time, two batteries can be connected in parallel and then connected to one circuit of the tester. The charging and discharging current is 1/2 of the original, and the effect is also very good.
3, the output combination method. For batteries that have been aged for a long time or batteries with serious self-discharge and serious vulcanization, this method can be used when the effect of water replenishment and charging recovery is not obvious enough. This method is more effective for severely vulcanized batteries, and this method is actually used. The charging current is best to choose 5A. Because of the superposition of repair functions, the repair negative pulse current is greater than the positive pulse, and 5A is selected to compensate for the offset of the resulting charging current.
4. Output parallel current increasing method. If it is repaired the battery capacity is large. If it exceeds 2OAh. Sometimes it is necessary to increase the charging current. At this time, two or more output terminals of the tester can be connected in parallel to the repaired battery at the same time to enhance the charging current. In the actual test, it was found that according to the difference of the battery, the T1000 digital multimeter DC 20A gear side test, the current of the side test instrument after two parallel connections of the battery gradually increased to the sum of the two currents.
5. Output parallel desulfurization method. The battery is severely vulcanized, and the battery with little effect has been repaired repeatedly. The repair function of two testers can be connected in parallel to the repaired battery at the same time to enhance the desulfurization effect. This method is not easy to master. It should be added in the same phase, otherwise, the desulfurization current will weaken, which can be judged by monitoring whether the voltage and current increase.
6. Output series boost method. This method is valid for batteries with a battery voltage of 24V or 36V, that is, connect two or more outputs of the tester in series and then connect to the battery, and the voltage of the two series is 24V. The Three-way is 36V. However, the actual test found that the voltage increased after parallel connection, but the current was still the selected current size. For example, both circuits are 3A current. The voltage obtained after connecting in series is 24V, but the current does not increase. When using this method, it should be noted that the current size of each channel of the Yuan tester should be the same. It must be started at the same time, for example, the voltage of three channels in a series is 36V. The charging current of each channel should be selected with the same size and started.
