Swap your McLaren battery out for an lead acid type

The standard Lion batteries for all McLaren models are expensive (with a lot of suppliers ripping people off on costs) and subject to long delays. Avoid all that (if you really need a new battery) by swapping out to a standard lead acid one. Needs some programming with a proper diagnostic tool but all of our dealers (New Zealand, Munich, Boston, Scottsdale) can do it as can any McLaren dealer.
