Battery status

Question : I WILL be overseas for three weeks.

My car will be left untouched.

I feel that having someone merely start and let it run idle for 15 minutes or so daily or every other day will be more harmful ( to the atmosphere ) and gives no ( technical ) benefit to the car.

Thus, I am thinking of disconnecting the power source ( ie the battery ) and let the car be "dad" during my absence.

Will this affect the circuits of the various systems, such as the alarm system, immobiliser, etc ? When the power source is re-connected on my return, would the various systems require re-tuning ?

Alternatively, if the car is left as it is during the period ( battery connected, no warm-ups / idling ), will the battery be drained excessively ?

Answer : Leaving the batter connected when you are away for long periods of time would result in the battery being drained by the clock and some other equipment that may draw small currents even when on a standby mode. Disconnecting the battery would be a better idea for the short period that you would be away.

One month disconnected would do no harm to the battery and there should be no problem when you reconnect it.
