Sport Series 12V Li-On Battery

[RBT0]

Based on your customer experience, how can I check status of a 570 12V battery?

How many days is it supposed to last with the car sat on the garage before it goes flat?

Any damage if it is let drop flat to 0%?

[RBT0]

Exactly.

So if I am interested in a car that had the battery flat once (god knows how incompetent some people are...) shall I ask for a replacement?

[RBT0]

What's the cost to customers?
I actually have an idea of actual cost to McLaren...

Let's put in this way.

If I buy the car and battery goes flat after a week, then I could claim a replacement under warranty, couldn't I?

Obviously part of the deal would be a battery charger, which I wouldn't use first week so to see if it keeps charge.

Just need to make sure dealer agrees battery should last 50 days...

The car tells you how much battery life there is. When you switch it off a gauge appears on the main screen showing how many days, mine usually says between 45 and 55 days depending on driving and if I've used the trickle charger. If you park it and it says 50 days, then return after a week and it says 20 days, the battery is toast.

I'm intrigued, how do you know the battery has been fully discharged in its distant past?

When I saw the car, battery was flat, had to release door with release cable inside....nice touch, it reminded me the GT3RS interior door handle lol

How can you tell others didn't and the one I saw it's fine? Yes need to try...
