How should Panasonic batteries be solved when they are not charged?
Perhaps some people used Panasonic batteries when they were not charged, so do you know how Panasonic batteries when they were not charged?
First of all, we will consider the failure of Panasonic battery, so we should first check whether the connection of charging circuit is reliable, whether the connection and plug contact is intact, carefully check whether the socket and plug have "fire" arc phenomenon, there are wireless circuit damage and break.
If there is no damage to the charger, whether the charging parameters meet the requirements: the initial charging current reaches 1.6-2.5a per unit; the maximum charging voltage reaches 14.8-14.9v per unit; the floating charging conversion current reaches 0.3-0.4a per unit; and the floating charging voltage reaches 14.0-14.4v per unit. So let's see if Panasonic batteries are drying up, that is, whether Panasonic batteries are seriously short of liquid. Irreversible sulfation of the plates should also be checked. The irreversible sulfation of the plate can be determined by measuring the change of its terminal voltage by charge and discharge.
It should be noted that when Panasonic batteries are charged, the voltage of Panasonic batteries rises very fast, some cell voltages are very high, which exceed the normal value a lot; when discharging, the voltage drops very fast, and Panasonic batteries do not store electricity or have little storage. In this case, it can be judged that Panasonic batteries have irreversible sulfation.
Secondly, the inspection and treatment of Panasonic battery failure. First, we need to connect the charging circuit firmly. If the charger is abnormal, it should be replaced. Dry Panasonic batteries should be supplemented with pure water or 1.050 sulphuric acid for maintenance, charging and discharge to restore Panasonic battery capacity. If irreversible sulfation is found, a balanced charge recovery capacity should be carried out. When the dry batteries are charged with liquid, the maximum current should be controlled at 1.8A for 10-15 hours, and the voltages of the three Panasonic batteries should be above 13.4v/only. If the voltage difference between Panasonic batteries exceeds 0.3v, it indicates that the Panasonic batteries have undergone asynchronous irreversible sulfation. For Panasonic batteries with irreversible sulfation, it is necessary to replace the whole group of Panasonic batteries or activate Panasonic batteries.
Don't panic when your Panasonic battery doesn't charge. Having read the above introduction, as a reference, I am sure you will be able to solve the problem better.
