[ri′zərv ′bad·ə·rē]Reserve Battery
a cell that is designed in such a way that it can be stored in an inoperative state for rather long periods and converted to an active state at the required time by bringing the electrodes into contact with the electrolyte or by converting the electrolyte into an operative state. The storage life of modern reserve batteries is 10—15 years and significantly exceeds the storage life of standard batteries.
