The location of a signal battery, aswell as any battery, is very separate room is desired which can bewell ventilated and kept dry at a moderatetemperature. The ventilation should befree, not only to insure dryness, but toprevent chance of an explosion, as thegases given off during charge form anexplosive mixture if confined. For thisreason an exposed flame should neverbe brought near the battery when it isgassing. The success of a storage battery ismeasured by the care it receives in daily. FIG. 6.

The battery should not be dis-charged beyond the safe limits or allowedto stand in a completely discharged stateas it will be badly damaged. iji ii at the surface of the liquid, on theli , in the glass tube-. in hydrometer illustrated by Fig. 9 is that used for signal batteries and can be placed in the cell itself where it will at a certain level corresponding to the specific gravity.
