Can you safely use a marine/ leisure battery in a Landy?

X-Eng have started selling em anorl. but with less AH and more CCA (though I suspect they've stretched the truth slightly on the CCA) as that rating will only be achievable under perfect conditions and perfect temperatures. The optima thing came about cos he quoted the CCA of the redtop and it confoosed me. Cos me memory is fooked up and getting worse.

According to Manbatt who are the UK distie for Numax, the X-Eng is one of their marine/leisure batteries that has been unofficially re-badged as a 4X4 one.

Is this true even though they're expected to crank doisel boat engines? The one I got has got a rating of 800CCA.

they eren't used on boats to crank staters that'll be the starter batteries job.
thats how it was on my narrow boat, the leisure pair took care of my leisure facilities.
 
I have used leisure batteries on both my Disco's, my Frontera and my Shogun. Mainly because I work in a boatyard and its what we have in stock. We also use them on our Defenders and the Transit for the same reason. The 85a/h seems to work fine on everything up to a 5.7 Chevy but it doesn't like the 6.354 Perkins or the 3.6l VM's we run. They seem to do most jobs OK and being deep cycle, they tolerate marine use better as they often get run flat with bilge pumps and things and not being used regularly.
 
I run a Marine / Leisure battery as a second battery on the Disco mainly to drive the winch. It has both post and bolt terminals (Very handy) 700 CCA and 110A/hr capacity,
the spec is actually higher than the main battery. Run it through a split charge relay to keep it topped up.

I was recommended this by the local battery centre when I mentioned winch, but I can still jump back to my main battery if thats a bit tired.
 
Not all leisure batteries will provide high CCA values and will suffer damage if used for starting frequently. Leisure batteries can have a relatively limited number of recharge cycles if discharged to low values although they do have better recovery characteristics from a deep discharge.

I can't see any reason a marine/leisure battery cannot safely be used in a Landy.

The specifications are up to par (800CCA and 86 Ah) and the distributor says it'll be fine, boat batteries have to start hoofing great doisil engines in boats and they'll take deep cycling and I'm forever running me batteries flat.

So I'll keep testing it until someone offers valid reason why it shouldn't be used / or it blows up. Whichever comes second.

ave got one in mine 110 cranking/ leisure. no probs
 
I have been using Marine batteries in my Series for a couple of years with no problem. Cranking is no problem at all - infact it jump start a dead battery without the landie being started where other cars, running, had no chance. Kinda suggests that the cranking capability is not a problem!
 
I have 3 of the massive Numax leisure batteries on the farm. I got them ages ago and phoned them to ask what the difference was between the leisure and marine/leisure. They said they had a slightly different case and dual terminals so I'm surprised peeps have been okay starting engines with them as up to this point I've been told they're not for that. These are huge beasts though (I have to get a guy to lug mine about or take double pilates classes!) and seem to take all sorts of punishment. If they last 25% less than an automotive battery but cost 40% less then you could argue they make sense. But I wouldn't want to risk my life on it and be stranded somewhere unpleasant. ;)

I'll be installing a big deep cycle battery to my lannie soon mate.

lannies are perfect for this kind of thing :)

Marine battery's usually have a gel in them for preventing it slopping about.
They aren't supposed to last as long as lead acid battery's (which you can extend the life of by topping up the levels so the plates aren't exposed over time)
