Still another good feature is that no attention is necessary until the charge is entirely exhausted; that there are no noxious or poisonous fumes, and that the permanent parts of the battery do not deteriorate with time, as is the case with other batteries.

It can also be equally well employed for open circuit work, such as burglar alarms, hotel annunciators, telephones, call-bell 'circuits and railway crossing signals.
