Size of hole/grommet behind battery?

[RobFlynn]

Anyone know the size of the hole/grommet behind battery (the one commonly used for leisure battery)?

Not 100% sure but i would guess 20mm ?

If you have an existing cable then you will need to slit the grommet to fit it without removing the cable so go for 25mm as you can cut it to length when fitting

There is no grommet in the hole currently. Want to put one in and trying to avoid pulling everything apart before I have one to put in.

I’m going to remove the existing wire.

25mm grommet fits perfectly.
