Using the Smart BatteryUnderstanding Temperature EffectsA typical plot of CG-5 service hours against the ambient temperature for theMoltech Smart Battery is shown in Figure 6 below. At low temperatures, theservice hours decrease rapidly for two reasons:• low temperatures reduce the inherent electrochemical capacity of the battery• the load on the battery increases as the temperature drops, in order tomaintain the CG-5 sensor at its constant operating temperature.To circumvent the first effect and extend the battery life under cold weatherconditions, an external battery belt (optional) can be provided. The batterybelt is strapped to the operator's waist underneath the clothing and therebykept warm. An extender cable to the charger plug on the Autograv providespower to the instrument.Once the external battery supply has been connected, the internal battery ifdischarged, should be removed, as it should not be kept in place for very longthereafter. When the internal battery has been replaced, the external batterymay be then disconnected without any interruptions of the temperaturestabilization of the sensor.MaintenanceFigure 5-1 - Typical CG-5 Capacity vs. Temperature(Moltech Smart Battery NI2020)5-3CG-5 Manual - part # 867700 Revision 2
