Storage of the battery (Mazda Familia BG)

Batteries that are not used for a long time discharge themselves and may be subject to sulfation. If such batteries are charged with a fast charger, they do not accept the charging current and become "full" too early due to so-called superficial charging. They are defective.

1. Before rejecting a battery, it should be checked.

2. Check the density of the electrolyte. If the density in all the cans differs by no more than 0.04 g/ml, the battery should be charged with a normal charger.

3. Check the battery after charging under load. If the values are not as required, the battery is faulty.

4. If the density of the electrolyte in one or more cans is significantly lower than in the others (for example, in 5 cans the density is 1.16 g/ml, and in one 1.08 g/ml), the battery has a short circuit.

5. To avoid premature aging of the battery, the stored battery should be charged every 2 months.
