Battery maintenance?

In charge mode when battery went down to 95-98%, it supplied the battery with 13.2-13.3V and 0.7-0.8A for few hours then it slowly reduce the current while increasing voltage.


This charging / maintaining profile seems wrong to me. Here is what a 0.8 amp Ctek does:

I need to hook up the watt meter again to confirm the current value in maintain mode. I think I probably over stated the current, it may be less than 0.2A probably between 0.1A and 0.2A. The voltage is correct at 14.1-14.2V, and it was confirmed with Multi-Meter.

I felt very comfortable with 0.1-0.2A supplied to battery in maintain mode, with this low current it is not possible to damage the battery.
