It's time to replace our Leisure Battery ? 100 Ah minus as we use our Mover regularly. Several different types available now I believe ? Advices invited thank you.
New Battery recommends please?

Before we Sold our caravan we brought a Tanya 120Ah Leisure battery and the new owner says it still going so far .
How much do you actually use your motor mover?
A motor doesn't really take much out of a battery. The manual for mine says average current is 20 amps, so taking a 100 AH battery from full to 50% charge would mean using it constantly for 2.5 hours.
Sorry, I can't recommend a battery. I've been using an old 80Ah car battery (that I happened to have sitting in the garage for over a year) without issue. I don't go 'off grid' and use my motor mover for maybe 5 minutes to hitch up at home then however long it takes me to pitch up on arrival at site.
The OP is seeking advice on a replacement battery not mover, but the links are useful anyway.
It may be useful to know the make model and year of theTerry’s caravan.Latest Caravans rely heavily on 12v so that should have a bearing on the final choice
I bought mine from Tayna too - a 110ah one as the caravan apparently can't have a bigger one than that.
I've been using Tayna for years for batteries.

I have to use our Mover in order to get off, and on our drive. 90 deg turn in and out and slight up hill going in. Ex Lorry Driver so no problem reversing it in (apart from drive-thru' speeding cars/vans?) but clutches these days are not up to the job as they were years ago.
When replacing a caravan battery, It helps to know what 12V dc equipment you have and what your usage pattern is.
For example, If you use your caravan off mains power for extended periods, then you will need a battery with big Ah rating, and because the battery may be significantly depleted before its recharged, it will need to be a "leisure or traction type battery that resists dropping its plate material when discharged. It will need a peak current rating (Cold Cranking Amps) that can cope with maximum current your caravan needs. The common big draw appliance is a caravan mover which can peak out at about 100A for a fraction of a second when you start to move, but generally the current drops back to a much smaller value once the van is moving. Whilst this may seem an alarming amount of power, the fact is most people don't run movers for very long, so the actual power used is often greatly overestimated.
But if you only need a battery to run a caravan mover to position the caravan before connecting to an EHU, then based on what I have said above, you can get away with a much smaller and cheaper car battery, provided its CCA is enough for the mover.

I once got a nearly new car battery from the scrappie for £14, lasted me years just using the MM.
Whilst this may go against the grain with some on here we changed to a lithium battery last year. Costs a bit more than a LA or AGM battery however I believe the benefits are worth it. More usable capacity, lighter (ours was half the weight of LA), 10 year warranty and doesnt discharge when not in use. With a solar panel it stays topped up in winter even with the alarm, something our LA never did as within 6-8 weeks it would be dead. You do need to check out your charger though as if its not suitable theres the additional cost of replacing for one with a lithium profile but I found the battery manufacturer very helpful in this regard
I can save half the weight of a LA battery by only taking one gas cylinder - so the weight-saving doesn't justify the extra cost for me.
