Thanks Gibbo, good to pick out a few key points from the full agreement.

As I said Neil there are twelve pages of small print to the battery lease,
They guarantee a working battery at the start of the lease and require notice within five days if it doesn't power the car on delivery.
I thought they would get a full state of Health assessment, prior to offering the lease as a new start point.
For all they know they could be into battery replacement territory in the first week if they don't
7.1 We shall supply you with a Battery that is in good working condition and we shall replace or repair any defective Battery providing you comply with the terms and conditions of this Hire Agreement and the manufacturer recommendations for charging and use of the Battery.
....
7.3 We shall provide you with a Battery that has sufficient charging capacity for the term of this Hire Agreement and any extension to the term. The charging threshold is 75% of the Battery's original capacity.
This little snippet from Speak-EV (2020) gives an indication of the response from a Renault Dealer to an enquiry about checking the battery state of Health of a Zoe.
Does anyone know where I can take my 66 reg Zoe to, to have the battery SOC (should be State Of Health SOH) checked, preferably in Portsmouth? I’ve rang Martins in Winchester as I occasionally go to Winchester, but they want about £200 to ‘test’ it, as it takes about 2 hours to properly check it.
Er...I think I smell a little dealer BS there...
Now I think I would get one of those dongles and the free CANZe app for under £20 and test it for yourself. Borrow someones smart phone to do it

if you dont want to enter the world of smartphones. Not sure if you can do it on a laptop (edit...there are ways and means like this
https://www.browsercam.com/canze-pc/ ). How else are you going to know whether your battery has dropped below 75% SOH.? Not sure if the Zoe has any indicator on the dash. The Leaf has its 12 "bars" recording State of Health on the dash display.
