Battery question

[Crossthreaded]

'Mornin all. I've been treating myself to a few "presents" recently - Most notably a capacitor type jump starter which I've written about earlier in this section of the forum. See here if you're interested: https://www.seatcupra.net/forums/threads/a-different-way-to-jump-start.479138/ I'm now keen to buy a "proper" battery condition analyser. I have access to one of the old heavy discharge (large resistor between two probes with volt meter to monitor battery voltage under load) but have a fancy to own one of the more modern testers which work, as I understand it, by measuring internal cell resistance rather than "whacking" it with a big current draw. The Topdon BT 200 or Foxwell BT 715 are "in the firing line" at this time. However I've spotted a problem with using them on more modern VAG stuff and maybe others too. You can't see the label on the top of the battery because of the fusible link cover obscuring the top of the battery. This is a problem because you need to know stuff like battery capacity (Amp Hour Rating) and cold cranking amps (CCA) - or European equivalent, maybe DIN or EN or other to program the analyser and this info is very often on a label stuck to the top of the battery and you can't see this because of the cover. Unfortunately the cover seems to be integral with the battery cables, so it looks to me like you have to disconnect the battery terminals, or maybe just one terminal? in order to move the cover far enough to read the label and I really don't want to get involved with that for the obvious reasons of possible loss of settings. Anyone got a way round this?

Hi folks. I see quite a number of people have had a look at my post here, but, so far, no-one has come up with a suggestion. I know I could always connect up one of my workshop batteries - Negative on the workshop battery to the earth point on the Scala's N/S inner wing and positive on the workshop battery to the positive battery lead clamp - before slackening and removing the battery clamps and then moving the cover out of the way. Or I could buy an OBD adaptor to allow me to connect the workshop battery via the OBD port (I don't have such an adaptor so would need to buy one. Come to think of it, maybe not such a bad idea as they aren't expensive.) I would much prefer an option which doesn't involve disconnecting the vehicle battery terminals at all though. No-one got any suggestions? - Polite ones please! Just to remind us what the problem is. I need to see the labelling on the top of the battery but can't because of the "gubbins" obscuring it.
