'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?
