I have to get new leisure batteries for my Moody 30 (separate starter battery is fine). I’m looking at either a pair of 130ah Hankook for £106 each or a pair of 100ah Yuasa for £125 each from Batterymegastore.co.uk. Both batteries have a 4 year guarantee.
On the face of it the Hankook appears to be the better buy but I would be grateful for others experiences of these brands and for a more informed eye than mine to have a look at the attached data sheets.
Thanks

I bought Hankook for my last boat and had no issues with them, but only ~ 2 years before I sold her. They have a decent reputation and I reckon I could buy several before an AGM became a realistic consideration.

Be aware as I think AGM batteries will sulk big time at the charge rate many boat engines can chuck out.

Ah! That's interesting, never heard that about AGM, maybe I need to change track. Can you point me to the relevant research pls?
Lots of us use them on narrowboats &
I'm also installing them on campervans with a smart dc-dc charger off a medium sized alternator via a 90ah standard lead acid cranking battery.
I'm happy to learn I've got it wrong, better now rather than later.

Google will be your friend, the link posted above even has a disclaimer at the end which states,

Please ensure your charging method can accommodate AGM batteries as charging at non-AGM charge settings can adversely affect the life of the battery. Why not read our AGM battery guide here or call us on 01706356356

Personal experience is on land rovers, fit agm and you have to tell the car via diagnostics that it has an agm which then changes the charging rate, not unusual to see over 15 volts with lead acid, and this may harm your agm.
Have seen voltages much the same on our previous boat, current one also charges at high 14 volts.

This bit again from the link above is very specific about charge voltage, it seems to low AND to high is bad for the agm, tbh I thought it was just the to high that was the concern.

No experience of Yuasa but my last pair of Hankook Leisures lasted 8 years (although had not failed) and the same replacement is doing great after 5 years.

I have fitted hundreds of Hankook batteries, never had a problem yet. Doubt if you'll get a problem with Yuasa either, but i don't see any benefit in paying the premium.

I've had over 12 years life from a couple of Yuasa car batteries.
One was a Halfords Battery labelled "made by Yuasa" the other an original fit in a Renault.
Current Yuasa , in the Renault , is 6 years old and doing fine. I'm hoping it will see me out.
IIRC I bought it from MDS Batteries in N. London but it was delivered direct from Yuasa's depot.

Any info on the life people are getting from Hancocks ?

I think the charging voltage is taken care of by the dc-dc charger which is easily set up for AGM and then gives the same step charging characteristics as a bench charger running off 240v, never going over 14.8v.....at least I hope that's what's happening ?

Think I'm alright, as I've been using the Ring dc-dc charger that Alpha batteries recommended.
I'm not sure that the Ring unit is suitable for a sea going boat but there are definitely Sterling & victron chargers that are. However, the additional costs of those chargers has to be factored in to the equation & if people are getting 8yrs of trouble free use out of wet batteries then there's a lot to be said for sticking with that.

So do AGM batteries charge at the correct level from an alternator when the engine is running?

I think you need a pretty sophisticated charger, in my case a Ring dc - dc charger like this: RSCDC30 - Ring Battery to Battery Charger 30 Amp with MPPT Controller - SplitCharge.co.uk
There are others avaliable from Sterling, Victron and Ctek that may be more suitable for a sea going boat.
Its unlikely that the alternator on your boat will be smart enough to control the charge without a charger specifically designed to manage AGMs.
 
Interesting caravan website ,they simply compared the weight of various batteries to gauge the quality and longevity of the battery.
On ebay it can give the shipping weights.
Suggests just how much lead is in a particular battery.
The lead content can vary considerably and is usually, but not always, price related.
Conclusion...... the more lead ,the better.

Can go over 15v if its cold if charger temperature sensitive. That's how i understand it.

That's certainly the case with my Ctek mxs.5 charger but it has an agm mode and the 3 agms I have are in tip top condition.
The Ring charger has a temp sensor that sits by the battery but think that's to sense over heating. Max output voltage of the ring charger 14.8v so no chance of a problem there.

Careful what you put in the search box on google!
