@Woo5ie , a TVR Chimaera 4.0 V8!! Fun!
@RichardS , I can't disagree with you, of course. Though we should educate some in recognizing that the quiescent drain on a 2006+ XK is rated at <35mA. That is 35 thousands of an amp! If the battery is 90Ah, 800 CCA... its going to take a lot longer than 30 days to drain!
In the workshop manual, section 4.2, it clearly states that batteries should be tested at 30 day intervals and charged at 90 day intervals, with the expectation and assumption that a sound battery is installed.
Not to mention that in some regions of the world, if you are parking on the street for 90 days... I'd be surprised if the wheels were still on it, which could negate the need for a battery, anyways.
And truly, there are periods within the calendar year that my vehicles sit for months on end, without issue.
So, back to 'what to do'. Fix the root issue or ignore it and play the charging game. We all have different approaches to this.
Cheers to all... global warming has afforded me a day of spring skiing ... in Feb! See ya!
