What electronics 4V battery cells in parallel problem? E-called electromagnetic 4V refer to the same voltage in parallel, the same type of batteries can be used in parallel, it is positive then positive, then negative negative, use of time is the sum of the individual battery life, charge and discharge are not affected, electronic battery, 6v of Battery capacity and 4v battery can be used in series, the voltage is 10V, can not be used in parallel, parallel words 6V battery to 4V battery charge, Beijing electronics, said battery brands, the result is a 6V battery discharge deficit, Shijiazhuang electronics battery monopoly, 4V battery charge violence. Above content provided by Tianyi Electric Co., Ltd. Hebei Cangzhou electronic scale cell production, we want to help a friend in the same industry. You can not use electronic scales have not used a few times now for the new batteries after what is the reason? Glass health scale electronic scale is one meter. This scale power consumption is very low, with automatic switching function, a new look at it sometimes hidden phenomenon is caused by poor contact LCD version, because the liquid crystal film is not the pins, so it is prone to this kinds of fault. First, I suggest you put LCD version with the board of conductor strips clean look, conductor strips can not be inserted upside down, the conductor strip has a 2 side is non-conductive, the board designated fixed-line pinch foot row, Finally, the original small screws tight, should be able to show the numbers, the question is not very complicated. Second, check the battery installation contact is good, tried to put before the battery cover a small piece of confetti plugged. Third, if it can not solve it, you can send professional repair overhaul center. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry.
