Care of the battery

From time to time it is necessary to perform the following works that the battery served longer and its power was supported maximum.

1 Always you keep the battery and details surrounding it clean. The surface of the battery has to be always dry as differently between separate banks there can be superficial currents of leak because of what the battery is discharged in itself.
2 Level of electrolyte has to be constantly at a ring on the lower party of the jellied camera. For a dolivka use the distilled water.
