Hope it is just a good charge which is required.
Negative off first , then positive, then charge it up.
Keep the key out of the ignition at all times until reconnected battery, (my imobiliser scrambled itself and had to be reprogrammed even with the key in my pocket so i am now very cautious to reconnect the positive first then the negative and not to cause any sparks on the re-connection).
