Narrative:
Power cart had quit and the aircraft and lights drained the ni-cad battery. The battery temperature was enough to cause the battery overtemp light to come on. We disconnected the battery from the aircraft to let it cool. It was going to take several hours to cool and I tried to find another battery, but could not find one. I decided to leave the battery disconnected and start with the power cart and fly the trip (which was 1.5 hours and my main maintenance base). My copilot decided to quit because he said the battery has to be connected for flight. We do have an MEL and I checked the regulations and now think he was right. I was thinking I needed to get the plane to the maintenance base and would be ok with both generators. Supplying the electrical power. I am single pilot exempt on this aircraft. Also no mechanics were available until the next day and it would have taken 2 more days to order and receive another battery. Would also suggest going to lead acid battery.

Title: A CESSNA CITATION II WAS DISPATCHED IN NON COMPLIANCE WITH THE MAIN SHIP'S BATTERY DISCONNECTED DUE TO DISCHARGED CONDITION.
Narrative: PWR CART HAD QUIT AND THE ACFT AND LIGHTS DRAINED THE NI-CAD BATTERY. THE BATTERY TEMP WAS ENOUGH TO CAUSE THE BATTERY OVERTEMP LIGHT TO COME ON. WE DISCONNECTED THE BATTERY FROM THE ACFT TO LET IT COOL. IT WAS GOING TO TAKE SEVERAL HRS TO COOL AND I TRIED TO FIND ANOTHER BATTERY, BUT COULD NOT FIND ONE. I DECIDED TO LEAVE THE BATTERY DISCONNECTED AND START WITH THE PWR CART AND FLY THE TRIP (WHICH WAS 1.5 HRS AND MY MAIN MAINT BASE). MY COPLT DECIDED TO QUIT BECAUSE HE SAID THE BATTERY HAS TO BE CONNECTED FOR FLT. WE DO HAVE AN MEL AND I CHKED THE REGS AND NOW THINK HE WAS RIGHT. I WAS THINKING I NEEDED TO GET THE PLANE TO THE MAINT BASE AND WOULD BE OK WITH BOTH GENERATORS. SUPPLYING THE ELECTRICAL PWR. I AM SINGLE PLT EXEMPT ON THIS ACFT. ALSO NO MECHS WERE AVAILABLE UNTIL THE NEXT DAY AND IT WOULD HAVE TAKEN 2 MORE DAYS TO ORDER AND RECEIVE ANOTHER BATTERY. WOULD ALSO SUGGEST GOING TO LEAD ACID BATTERY.
