The last couple of flights when starting the cranking has been very sluggish. This morning it was barely turning over, but I got it started. I did a 25 min flight and the EFIS was reporting a steady voltage of 14.6V. No issues in-flight. Immediately after shut-down the EFIS was showing about 12V. I tried starting it again. During cranking the EFIS showed the voltage dropping to between 1V-2V.
Does this sound like a bad battery, or could it by my alternator or starter?
All components including battery, starter and alternator are 6 years old. The battery has been stored at room temperature during the winter (non-flying) months.
