Battery positive and negative sequence is a very important.
To remove the old car bettery, must be in accordance with the "remove the negative and positive down" sequence, because the body is connected with the car bettery anode (Da Tieduan), if the demolition of the first positive words, in the disassembly process of the screwdriver may touch the body, once touched, it is equivalent to the battery positive and negative direct connection, it may lead to short-circuit and burn the battery. Therefore, when the demolition of the "first negative after the positive pole", but in the installation, the contrary, follow the "first positive pole" of the order.
