We can see at the end of the graph that it finally hit the end of the constant-current phase and entered constant-voltage, signalling the battery is finally full. So we know it will actually charge it fully, but we may have to do some tricks to get around the 5-hour limit.

"But Björn, if you can't increase the charging current, what is the point of a bigger battery anyway?" You're right. If we run the mower 24/7, then a bigger battery doesn't mean more time mowing per day, it just means fewer and longer charge cycles. But that has value too. Each charge cycle adds time spent for the mower to find its' way back to the charger. It does this in several ways, but one fallback is to follow the edge line. If this is done often, it will cause visible ruts there.
