Solution of YUASA Battery Can't Charge

First of all, we will consider YUASA battery failure, so we first need to check whether the charging circuit connection is reliable, whether the connection and plug contacts are intact, carefully check whether the socket and plug have "fire" arc, where there is no line damage.

If there is any damage to the charger, whether the charging parameters meet the requirements: the initial charging current is only 1.6-2.5a/the maximum charging voltage is 14.8-14.9v/unit, and the conversion current is 0.3-0.4a/unit floating charging voltage is 14.0-14.4v/unit. Then we must check whether there is drying phenomenon in Tangshao battery and whether the liquid of Tangshao battery is serious enough. The irreversible sulfation of the board should also be checked. The irreversible sulfation of the plate can be determined by measuring the change of terminal voltage by charging and discharging.

Attention should be paid to the charging of YUASA batteries. The voltage of storage batteries rises very fast. Some single grid voltages are especially high, which are much larger than normal values. The discharge voltage drop is very fast. The storage batteries do not store or store electricity. The above situation can be judged as irreversible vulcanization of Panasonic battery.

Secondly, YUASA battery fault detection and treatment. We must first connect the charging circuit and replace the charger. YUASA battery should be charged and discharged with pure water or 1.050 sulfuric acid to restore battery capacity. If irreversible YUASA is found, the charge recovery capacity is balanced. After charging, the maximum current should be controlled at 1.8A and the charging time should be 10-15 hours. The voltages of the batteries are all above 13.4 v/s. If the voltage difference of the battery exceeds 0.3v, the battery shows that irreversible YUASA occurs asynchronously. For batteries with irreversible YUASA Panasonic batteries need to be replaced.

Don't panic when the battery is not charged. After reading the above introduction, as a reference, I believe you will be able to better solve the problem.
