OK! So, aside from discussing the CTEK MXS 5.0 in general.. In my specific application, the battery WAS ran down to "dead enough to need a jump start" in the recent overheat/blown radiator incident in the Subaru. (Lots of jump starting from the Taurus. This is now my profile banner pic, too. Just for my own reference. A starting point and memento, if you will. Cool.)
The battery.... this one:
... I believe I charged it up for about a day and then put it back in the car for about a week and now and charging it in this manner until the engine comes.
Here is the voltage ️
And yes, it's probably about 100 degrees out in the garage I just don't realize it. Sides are NOT bulging (they do not squeeze in as previous batteries I had did, like the Infiniti battery) and it does NOT have caps to check the water.. this concerns me a little bit.
So, scenario set up.
Now as to the CTEK MXS 5.0 in general...
1. It is on Stage 7. I thought I read somewhere it maintains Stage 7 at 13.6V.. does the voltage change somewhat with heat?
2. Can Stage 7 KILL a battery?
3. Since this battery was discharged for some days.. is this an acceptable reading, before it gets to Stage 8 "in a week?" (I didn't believe it at first but it switches to Stage 8 at 10 days to the second/minute. It's amazing.)
4. The Stage 7.. does it have any effect to help the battery hold charge, or extend the life?
5. Is my battery screwed because it was low on charge for probably a few days, maybe as many as 5?
6. Is the CTEK MXS 5.0 one you use regularly?
Let's make this about the CTEK MXS 5.0, maybe Stage 7, and if you like it more than or less than other chargers, and why!
And yes, most of the labeling has been "wiped clean" off the battery just from use of Tire Foam etc. Most of under the engine bay is like that.
