From: "clivesutton" Hi Jonathan, To contribute to to your original question (which is indeed fascinating) i think the answer may have to do with the internal chemistries/construction of each, the way each Mfr interprets e.g. CCA and CA testing and their market focus. I believe that: Varley have the best Pulse Hot Cranking Amp performance because they are of sealed bog std lead acid construction. But this comes at the price of life (from apprenticeship days i recall that the pure lead plates can buckle under continuous high-amperage discharge and eventually this and sulphation shorts an individual cell, dropping the battery voltage). The Odessey and the Tanya are both Absorbed Glass Mat tech - a tech which seems to offer a better life at the expense of lower Cold-Cranking Performance and capacity - a kind of compromise. In my view this is perhaps best type suited to our application given the sometimes lengthy time gaps between use. The 912S's higher capacity starter motor is rated at 0.9kW at 12v which translates to a demand of 300A for 1 sec and then 75A for the remainder to the maximum 10-second start cycle. So providing the battery cabling is short and 4SWG/16mm2 those were the reasons for my choice of the Odessey battery. Whilst Odessey list Aircraft use as an application, Tanya seem to list the EC680 as predominantly a Motorcycle battery. Even more curious is that Tanya will sell both batteries - with the EC680 being 20 cheaper. Vibration durability perhaps? https://www.tayna.co.uk/industrial-batteries/odyssey/pc680/?gclid=EAIaIQobChMI7uHf9L244QIVz5TtCh17tgzhEAQYAiABEgKa3fD_BwE https://www.tayna.co.uk/motorcycle-batteries/enduroline/ec680/ There is also a lot of re-badging going on in the battery world and i wonder if the PC680/EC680 is an example of that Hope it can add to the debate . . .

From: "JonathanMilbank" Clive, your reply is really helpful and your "re-badging" suggestion is more or less borne out by a man I spoke to at Tanya, although who's to say whether the "own brand" EC680 is of just as high a quality as the PC680. The 20 reduction in price might suggest cheaper components and processes. So I "bit the bullet" and ordered the Odyssey, after having been beaten into submission by the overwhelming flood of testimonials in its favour. Thanks to all for the repeated "lashes with the Odyssey whip". I feel so much better!
