I was out today and had cause to use the IIDtool without a power supply attached and I got the "low power shutting down" message. I had a small multi meter with me so I checked the voltage across the battery and it read 12.25v. I know this is not fully charged but it also doesn't seem that low to be shutting down. Has anybody else taken a volt reading at this point, is there a problem with the battery or does using the IIDtool take a lot of power out of it. 2010 3.6TDV8 Stornoway Grey/ Black interior - gone
