The Basic battery(GEB111) or the Pro battery(GEB121) is recommended for T105/T110 instruments. As an option, sixindividual cells can be used with theappropriate battery adapter GAD39.Six individual cells (1.5 V each)produce a voltage of 9 Volts. Thebattery indicator in the display isdesigned for a voltage of 6 Volts(GEB111/GEB121). For this reasonthe charge state of individual cells isnot indicated correctly. The batteryadapter with individual cells shouldtherefore be used as a backup. Theadvantage of individual cells is thelow self-discharge rate - even overlonger periods of time.T105/T110-1.3.0en13Simple measurements
