Jump starting an aircraft isn't smart. The right answer is to trickle charge it, however dull that is and then do a capacity check.
There are a number of issues. Firstly, if there is an excessive charge rate, the battery can overheat. You can't control how much of the jump current passes to the battery
Secondly a hot battery requires less current to charge, but the increased temperature allows/causes more current to flow. On some batteries this can lead to thermal runaway/excessive charge rates/popping of the circuit breaker

FInally, it will take about three hours for the alternator to charge the battery back to full capacity. So for the duration of the first flight there is risk associated with insufficient battery reserves.
