AGM battery does not reach storage charge

Hey community,

I cleaned my car while listening to music. After half an hour, my vehicle indicated that the battery voltage was low and the ignition switched off.

I then connected my Blue Smart IP65 Charger and saw that the battery absorbed a significant amount of energy in bulk mode. Unfortunately, I had to interrupt the charging process because I had to leave. Later, I continued charging overnight.

I was surprised to find five additional individual cycles, but the storage charge was never reached. Instead, after 4 hours in float mode, a new cycle started each time. What could be causing this behavior?

When I interrupted the last cycle at float time 165 min, the current draw was at 0.1A.
