Storing a McLaren: Battery Care & Long-Term Storage Guide
How to store a McLaren properly between drives or over winter, since low-voltage battery drain is one of the most common complaints reported across every model on this site.
Frequently asked questions
What's the single most important thing for a McLaren that sits for weeks at a time?
A proper battery tender/conditioner designed for vehicles with complex electronics. Modern McLarens draw a small continuous current for ECUs, immobilisers, and telematics even when parked, and an unmaintained battery is the single most common cause of the electrical gremlins reported across every model on this site.
Does tyre condition matter during storage?
Yes. For shorter storage periods, slightly over-inflating the tyres helps reduce flat-spotting; for multi-month storage, taking the weight off the tyres with axle stands is the more thorough approach.
What should I check with my insurer before storing the car?
Confirm whether your policy should be adjusted for a storage period, and separately confirm you're on an agreed-value policy rather than a market-value one, so a total-loss payout while garaged matches what the car is actually worth to you.
How often should a stored McLaren actually be started or driven?
Regular short inspections (checking for leaks or moisture) plus periodic actual driving — not just idling — is the recurring advice. A battery tender reduces electrical risk but doesn't replace running the car and its systems occasionally.
