Take with a very large pinch of salt! "Leisure Batteries" are pretty much bottom of the pile (pun) when it comes to protracted use - A 4 year guarantee sounds good, but they're often hedged with all sorts of caveats should you need to actually claim.
Do they mention "DOD" (depth of discharge) when muttering about "500 cycles"?

Leisure batteries are just that, they are for leisure and with a CCA of 1050 they must have pretty thin plates, sealed for life means you can't check the SG or top them up. Personally I'd steer well clear.

The words cheap, good and batteries do not go together. The scrap price of lead is such that even a clapped out set of fork lift batteries is worth much money. Many people have good experience of second hand UPS or standby telecoms batteries so perhaps it's worth going down that route.

Good luck, Paul

Those used batteries seem quite expensive.  24V x 365Ah =  8760Wh @ 800 Euros = 0.09 Euro/Wh.  I paid about 20% more for brand new batteries from sunlight.gr including delivery from Greece to Spain.

If I was buying a big battery pile I'd get lithium iron phosphate: http://www.ev-power.eu/index.php?p=p_55&sName=lifeypo4-big-cells-%283.2v%29
They cost 0.31 euro/Wh so are about 3 times the price of lead-acid but should last longer, have much more useable capacity and much higher max load. You would be pushing the norms by doing this and it certainly can't be called a cheap option.

Oops  Embarrassed  IMO second hand batts tend to be quite expensive compared to new ones, given that you generally don't know their age, or how they were charged or treated.  Spending only slightly more (about 30% more using the above corrected numbers?) for brand new batteries seems preferable to me.

And me Stephen, I think when Billi bought his four years ago there was a much bigger price difference between new and used. Now with more interest and the rocketing price of scrap it hardly seems worth the risk, especially if you can reclaim the VAT.
