Worked this morning ...

My cheapo battery checker (electrolyte float-type) showed all six cells very low charge in the main battery. Also was a little low on water (added after). Then charged the battery, but quickly said it was fully charged. Only gives 12.0 V with car off (should be about 13.6). So looks like I at least need a battery!

Darn ... was going to drive the XF next week. Now would like to find a replacement OEM (Varta?) battery, or make a long trip to Sam's Club for the cheapo Eveready as a temporary fix.
