Knowledge of lead-acid batteries

New and old batteries, different types of batteries and different manufacturers of batteries, it is best not to mix. Due to the new and old batteries, different types of batteries and the size of battery internal resistance produced by different manufacturers, the battery in charge and discharge is obviously different, such as series use will lead to a single over-charge or under-charge; Parallel use will lead to charge-discharge bias, the current of each battery will not be uniform, charging will not be uniform.

  During the operation and maintenance of the battery, it is necessary to check the following items: first, the end voltage of the battery, the charging current and the floating charging voltage of each battery; second, whether the connecting bar of the battery is loose or not, and the corrosion phenomenon; Third, the battery housing has leakage and deformation;

  Battery pole, safety valve around whether there is acid mist overflow, rust, etc., if necessary, pole coated with butter.
