as far as i recall, even if you disconnect the battery it’s still going to lose charge?
probably not as fast as when you have it connected to an immobilizer – but i still think that when you return to your car after a month, she wont start.
if you do take you battery out, OR unhook the positive terminal. i would seriously recommend using a battery charger that trickles the power into the battery to keep it alive or charging. there are a few of these on the market ranging from R 1000 – R 3000.
the worst thing you can do for a battery is let it go flat. when it goes flat – it significantly decreases the lifespan of the battery.
batteries are not cheap – perhaps the 4×4 guys can publish an article for you on Battery maintenance and care. ive learned many lessons from doing things the wrong way and trusting mates opinions than actual expert advice or fact.
i too would appreciate the insight.
