Storage batteries which long were not used, discharged independently, and, except that, their plate can be просульфатированы. If these batteries are charged with the help быстрозарядного devices they do not absorb зарядный a current or because of a so-called superficial charge appear too early "completely charged". They seem faulty. But before to consider these storage batteries faulty, they should be checked up.
Check up electrolit density. If in all cells electrolit density разнится among themselves no more than on 0,04 g/ml this storage battery can be charged standard зарядным the device.
If the density in one or two next cells deviates more considerably (more than 0,04 g/ml) the storage battery has internal short circuit and is faulty.
After gymnastics test the storage battery under loading. If at it preset values it is faulty are not reached.
To prevent ageing of the storage battery, it is necessary to recharge the stored battery each three months.
