Grim...good information but I have a question about this process. To help keep my battery charged I use a CTEK 4.3 and place it in snowflake mode and use the cigarette lighter plug. Everything seems to proceed through the charging process as you described except at the end. I go out the next day to check the results and notice no lit lights except for the power light is flashing green. The instruction booklet doesn't mention this so maybe someone on this forum can explain. I notice my car is fully charged when I take it out for a drive so it much be charging the battery.
