Why Switch from Lithium to Lead-Acid?
Lithium batteries are often used by McLaren due to their lightweight design and high energy performance. However, some owners choose to switch to a lead-acid battery for several reasons:
- Cost: Lead-acid batteries are less expensive, making them a practical option when frequent replacements are needed.
- Reliability: AGM lead-acid batteries are considered more tolerant of deep discharges and extended periods of inactivity—common for seldom-used sports cars.
- Availability: Unlike specific lithium-ion models, lead-acid batteries are widely available and can be replaced quickly.
Our Intervention: From Les Sables-d’Olonne to Dieppe
As part of a service for a client, we traveled 480 kilometers from Les Sables-d’Olonne to Dieppe to carry out this operation. This distance reflects our commitment to delivering bespoke service—even for complex projects.
Key Steps of the Operation:
- Initial electronic diagnostics: We checked the energy management systems to prevent any conflict with the new battery.
- Installation of the AGM lead-acid battery: We selected a high-quality battery suited to the vehicle’s needs, accounting for the added weight.
- System recalibration: As always at Thorney Motorsport, electronic modules were reprogrammed to avoid any errors or malfunctions.
- Thorough testing: After installation, we performed on-road tests to ensure the vehicle’s performance remained optimal.
