Brainless wit!!
Must have found my trade papers and engineers degree in a corn flakes packet!! Heard they were handing them out with brains!!
Anyway i think the Delkor 27H-710 cranking batteries are excellent, i run two under my gu bonnet, and as i said earlier, deep cycles take too long to recharge, this is why you run your fridge from a cranking battery.
If you are camped in one spot for a week, deep cycles will not accept a fast charge, because of the design. Cheaper ranges of deep cycles have thicker and fewer plates(unless you run optima or the exide extreme), and therefor build up a surface charge on the outside of the plates, telling the voltage regulator the battery is almost charged, the charger will then back off the amps and supply a trickle charge.
Cranking batteries on the other hand have thinner and more plates, which dont build up surface charges, so the electrons will absorb faster into the lead plates, and give you faster recharge times, which you want when your camping in the one spot for a period of time.
The exide extremes and optima's and other Absorbed Glass Matt batteries work in a similar way to cranking batteries, but give you deep cycle characteristics without slow recharge times.
You may have heard of the Outback battery charger which is built by christie engineering, if not, look it up and youll see what product i designed and now manufacture by the thousand.
We do have hundreds of calls every day about the same problems, and if we could get people to buy an exide extreme, or optima then we'd be rich, as we are a reseller of these batteries, but some people cant justify the crazy prices, and one of the next best thing is the Delkor range of cranking batteries, from Alcoa battery importers in Penrith.
Delkor also make a range of deep cycle batteries, but they are NOT calcium type, just the norm lead acid, and recharge times are slow.
