We'll also be pulling the breaker supplying it when the robot is not in use

It is also best to disconnect the backup battery from the on-board charging circuit. Without an attached RC or connection on the 12V supply end the circuit still discharges through the charging circuit to ground. Granted we only measured 6-8ma, but why start off with a partially discharged battery. With supply side connected but without the main battery the discharge rate will be much higher (assuming things like victor fans, etc. are directly connected to breakers and not via spikes).
