I have been charging my 2013 GS battery in the car for about 3 weeks, with a CTEK 4.3, everything has been fine, except today noticed the charger light was at 4 instead of 7 or 8. I have the original OEM battery. Looked to see if there was water in a cell and really couldn't see anything. Where should the water level be?

Ok, the reason why battery charger stopped; power outage and it had to restart and to get from level 4 to higher takes a couple of hours, so, no problem with charger. Water level for battery can be found in manual, it is difficult to see level but a couple of cells did look low, and I put distilled water to bring them all up to approximate correct level.
