hey, i went away for 2 weeks and came home to find my 06 wrx battery flat. Electrics still turned on but the brant keypad wouldn't illuminate and the engine wouldn't tick over.
I jump stated the car no worries and it was fine for a day but leaving it over night left the battery flat again. So i jump started it again and left a trickle charger on it. I tested the battery first and it was showing it was holding 12v. I left it charging for a few hours and re tested and it was showing flat battery condition and the car again wouldn't start.
Its an RAC battery which i have no idea how old it is. I'm assuming i need to pull this battery out and replace it but am weary of the brant system.

After searching i found the info about the 2 man job and disconnecting the neg terminal for a while and putting in the code on the brant but was wondering if this is a definitive thing that is going to happen or a possible thing.
Also is 2 weeks really long enough for a flat battery in your opinion??
