12V автомобильный аккумулятор ремонт удаление серы уменьшенная пластина аккумуляторной батареи для ремонта пластины

The version has been upgraded.The non-replaceable fuse structure now used has added a polarity protection circuit, connected to the positive and negative poles of the power supply, does not burn the fuse, and does not damage the board.

The life extension device produced by our store is very simple to use. Just open the battery box and install it at both ends of the battery. The connection diagram is as follows. The terminal is marked with (+) positive and (-) negative. Connect the positive wire to the red wire (positive pole) of the battery and the negative wire to the black wire (negative pole) of the battery. After connecting, you can see that the blue light of the life extension device is on. The use of the battery is exactly the same as usual.

This board is not equipped with clips and cables, please contact

Length about 6.2, height about 2.5, width about 4 cm
Battery capacity: 4-200AH (because the board is on and on the battery, it will consume the power of the battery. When the battery is small, such as 4AH, you need to recharge it once a day, and charge it once every 7 days for more than 20AH)

Battery type: Lead-acid battery

The current limiting resistors of this board are two in parallel, R13, R14, when connected in parallel, the current consumption is about 60-70MA, and one current is removed at 25-30MA,

Refer to the use tips.In the initial repair, both resistors are retained, and the repair speed is faster.After the battery capacity has been restored, you can cut one of the resistors and keep only one, so that the current is small, and it is used to extend life and prevent sulfuration.

There are many battery repair products, called by many names: desulfurizer / repairer / life extender / recoverer, etc., their working principles are roughly the same. I think it can be divided into two categories: life extension devices and repair devices. The difference between a repairer and a life extension is:

The repair current of the life extension device is relatively small. Its main role is to offset the sulfur generated during the use of the battery and has a certain repair effect. The repair ability is not very strong and the repair speed is slow. However, it can be connected to both ends of the battery for long-term use and will not affect the battery. If damage occurs, the battery's repair degree is 100%, which is more conducive to extending the battery life, and is especially suitable for new batteries.

The repairer has a large repair current and a fast repair speed. However, due to the large repair current, long-term use will damage the battery, so the battery cannot be repaired completely, and the repair degree is generally 90%. Large-capacity battery life extension can be used as a small-capacity battery repairer.

 Life extensions produced by small shops are generally installed in the storage battery, and have a long-term effect. The new battery has an extended life of 1 to 2 times; it also has an effect on the old battery, as long as it is not completely damaged (for example, if the new battery of an electric vehicle is used for 20 kilometers, the complete damage can only be used for tens of meters, or shorter). It can also repair the battery to restore the performance of your battery and use more time. (It is best to use with the repairer, use the repairer to basically repair the battery in a short time, and then use the life extension device to maintain and restore the battery performance in good condition for a long time)
