Batteries for iGauge, AMEtrolog, CGM and Multilog gauges
The Metrolog down hole memory gauges are powered by special lithium based batteries, called Smart batteries.
Thanks to the very low gauge consumption, the Smart batteries last much longer than usual lithium batteries. Moreover, special Smart batteries can be used for extra long duration jobs (up to 2 years).
A Smart battery knows what its initial energy is. During use (when the gauge is in acquisition mode), the battery records the energy used by the gauge, taking into account the surrounding temperature, the current programming and the actual gauge consumption. The remaining energy is recorded by the battery by subtraction. The parameters needed for the calculations and the required statistics are stored permanently in the battery, so a battery can be switched from one gauge to another without information being lost.
Smart batteries are designated by a letter and a two digits figure. The first letter indicates its voltage and geometry. The two digits figure indicates its maximum operating temperature in 10 °C
