Haven't driven the NSX for about a week and it seems to have a flat battery now. (This happened a few weeks ago too and then I jump-started it from another car and drove it around for an hour or so to charge it).

Thought I would take the battery out to check its condition and either replace it or charge it fully using a charger. Problem is the alarm goes off when I disconnect both or either one of the battery terminals = upset neighbours! Needless to say, the battery is still in the car and uncharged.

Does anyone know how I can remove the battery without triggering the alarm system? The handbook strongly advises against charging the battery while still connected to the car.

Thanks,

Matt
