Leisure batteries

[maingate]

Go Outdoors have some 75 Amp hour Leisure batteries. They are physically not that big and might fit in place of one 110 Ah battery to increase battery life.

They are £49.99 but you will have to pay £4 to get their discount card. It is worth doing as I have bought a number of items for the m/home at better prices than other leisure outlets.

Am I missing something here? Why would one wish to fit a 75AH battery in place of a 110AH? Or is there a typo in the OP?

Presume you mean replace 1x110A with 2x75A £100 for 150A seems fairly good.
Although I prefer starter batts for leisure use in case I ever need an emergency engine start.

Any leisure (deep cycle) battery is going to be suitable for occasional use as a starter battery.

More to the point, the way some RVers use their rigs, it makes sense to buy the cheapest starter batteries available for use as house batteries and accept the fact that they are not going to last all that long - but almost as long as would deep cycle batteries in that application and at half the cost

i just bought a new battery for my trailer a 100amp truck battery wet normal starter t go in the bank of batteries . i got it from big wheels here in roche 84.50 inc vat. as a matter of interest cornwallbatteries were dearer .but did say they could do a liesure battery 110amp for 79.78 inc vat. thought good price but driving a round trip of 25 ml it s not worth it . you do have to shop around . i have tried liesure batteries in the past and never had anymore lasting or any better performance than a truck normal battery. but you pays your money makes your choice . must say i run a coupl at 100amp as they can also fit the unit if needed .
cheers alan.

Leisure batteries do not have high Cold Crank Amperage particularly noticeable at the time I'm most likely to need high cranking. 6 plates not 12 so I'll stick with starters.

I thought that the term leisure battery is a laymans term for deep cycle which means that the battery is made for taking a full charge and running down very low and then charging up again.
But a starter battery is better maintained at a permanent high level of charge.

Which is in effect what I'm stating in my previous post, that the 6 plates generally found in leisure batts allow deep discharge, being stronger and able to withstand this kind of abuse.

If you read that guy Stirling he reckons most "leisure" batteries on the market are actually little more than starter batteries slightly beefed up which is why they don't last any longer. And that guy knows a lot about batteries.

You can buy proper traction batteries which are designed for powering vehicles to the point of almost total discharge. But they are extremely heavy and extremely expensive neither of which qualities are suited to motorhome and leisure market.

That's why all the advice I have seen from experienced people seems to be forget about "leisure" batteries and just get lead acid batteries marketed for starting. This seems a good strategy especially if you don't cane the batteries and just go for a 1/3 discharge or so before you charge again.
