6. NiMH is the preferred option over the obsolete Nickel Cadmium type NiCad NiMH types have a higher capacity than NiCad batteries and they suffer less from memory effect However NiMH batteries have a higher selfdischarge rate and will be exhausted in a few months if not re charged Lithium Lithium batteries are more powerful but they are usually more expensive to purchase compared to Alkaline types They are not rechargeable They are toxic and should be disposed of properly at the end of their life in a hazardous waste facility BATTERY LIFE AND BATTERY LEVEL INDICATION Battery life is dependant upon the battery type frequency of system use the interval between use and ambient temperature Maximum battery current is drawn when the CIST 883 Readout unit is Bluetooth connected to the PC Assuming this is a rare event an 18 month battery life can be expected when using two AA alkaline type batteries based upon intermittent usage Battery level indication is displayed for the first 3 seconds after the unit is switched on Page 17 of 23 DO NOT LEAVE THE BATTERIES IN THE CIST 883 READOUT UNIT FOR LONG PERIODS If the CIST 883 Readout Unit is to be left for several months without use the batteries should be removed from the Readout otherwise corrosion from the batteries may cause damage to the internal electronics Care of Equipment Do not allow sharp edged objects to fall onto or press into the display window of the CIST 883 Re
