Life of a battery

I wonder if you can give me some advice.My leisure battery is over 6 years old. It was in the van when I bought it.In the Bilbo its located under the drivers seat.Very difficult to get to and will mean removing the seat and swivel to get it out.
How long do they last?

You're on borrowed time

Mine's under my swivel seat and it takes me about 2 minutes to get at the batteries to check fluid levels. Well, a lot longer if I've misplaced the right allen key!

Obviously not the same make of motorhome. But I removed the seat in my old Ducato several times, it was actually quite easy. As above poster notes only a couple of mins.

this cold weather does show up a weak battery, now is the time to consider replacing it, rather than wait until it lets you down. Or you can take it to any decent accessory centre to have it tested in situ
providing it is possible to get to it.

My last van was a 2002. Bought it in 2005 and sold it in 2011. Gel battery under seat so couln't get at it. Didn't have a solar panel and would be carefull if spending a couple of days without hookup. Always recharged ok on hookup or via engine. Never let me down once! Engine battery still original when I sold it! Lucky? Always kept an eye on the needle readings on the control panel so as not to run batteries down too low.

Both Leisure and engine battery are over seven years old. On permanent EHU at home.
The last leisure battery I purchased was over ten years old when we sold last caravan.

They last until they fail. There is no rule of thumb. Neglect is the biggest cause of failure.

The thing with leisure batteries that is more important than even ampere-hours is maximum cycles of charge.
If you are offered a battery which doesn't state that information, don't buy it.
Many leisure batteries will have 150 cycles of charge. That is from 11.8v to fully charged just 150 times and then it is a dead, deceased, battery-no-more battery. Recharge from say 12v to fully charged is half a cycle, roughly.
There are batteries that will give 1000 cycles but the best you will usually find is 500.

If your battery is really difficult to get at, look for a "sealed lead-acid". They are maintenance free and much better performance than gel or AGM. If there is room, go for semi-traction.
