A clever battery terminal clamp, which releases it's grip on the terminal post as you tilt the cover upwards, (& tightens it's grip as you push the cover downwards), enabling the battery to be disconnected quickly without the need for any tools.
It has red plastic cover and is for the POSITIVE terminal, (we do also have a blue one for the negative terminal: click on "Accessories" above this text).
This clamp fits a standard 20mm round positive battery post as used on most European cars, as long as it is in good condition (and has not significantly reduced in size).
It will not fit the smaller Japanese type battery posts or the square 'ford' type posts.
Many French classic cars have earthed components (such as battery mounting brackets) very close to the positive battery terminal. For this reason there is a risk of high-amp shorting when fitting a positive battery terminal. This can cause injury/fire/explosion.
When disconnecting a battery, always remove the earthed terminal first. When connecting a battery, always connect the live terminal first and ensure that it is not touching or close to any earthed component, before connecting the earthed terminal. Some types of replacement battery terminal may not give sufficient clearance on some cars.
In such circumstances we don't recommend that this type of clamp is used for the positive terminal. (We do sell a similar clamp for the negative terminal).
