Most Aston Martins do not need to be parked for long before voltage starts to fall below their comfort zone. If the car is not used weekly, a tender should usually be part of the ownership routine.
Use the right tender and the right connection method
Match the tender to the battery type fitted to the car and use the approved connection points or lead.
A poor-quality charger can create as much trouble as no charger at all.
Make the routine easy enough to stick to
The best tender setup is the one you will actually use every time the car is parked.
If connecting the tender is awkward, fit a proper quick-connect lead where the official procedure allows.
Do not use the tender to hide a dying battery
A tender can maintain a healthy battery, but it should not be used to excuse a battery that is clearly tired.
If the car struggles after a proper charge, move to battery testing rather than endless topping up.
Checklist
- Confirm battery type
- Use a known-good tender
- Check the connection point regularly
- Replace weak batteries before winter
