- Before rejecting the battery, it is necessary to check it.
- To check electrolyte density. If density in all banks differs no more than on 0,04 g/ml, the battery should be charged with the normal charger.
- To check the battery after charging under loading. If values do not correspond demanded, the battery is faulty.
- If electrolyte density in one or several banks is much lower, than in the others (for example, in 5 banks density is equal to 1,16 g/ml, and in one 1,08 g/ml), the battery has short circuit.
- To avoid battery presenilation, it is necessary to charge the stored battery each 2 months.
