I would expect a battery to last more than 5 years if it is looked after.



I like 2 x batteries because if a cell goes down one, can disconnect that battery and one is still up and running till getting a replacement.
2017 we were away in Europe for over four months. Last summer and some of autumn we just spent in Flamborough and that was it. The van didnt move for 7 weeks but we were fine on Solar. Later on in the back end we hooked up.

two batteries means another 25kg over the back end and IMO just not needed as one is more than enough for the times we are off hookup and in the winter I would be on hookup mainly anyway. Only time its an issue is late autumn really if we are abroad. Its just a battery at the end of the day, the cost of just over a full tank of diesel. If it dies, just get another one. I would say five years of heavy usage is pretty good. It owes me nothing.

It was a pretty dismal end to a long trip really. The old scooter (Pig 1) coughed its last around the same time as the battery decided to give up the ghost.

I got an Alphaline battery in the end, 125ah. To be honest Ive never thought it was quite as good as the old 110ah that was in there when we got the van seven years previously but to be fair our usage has increased dramatically over the years and especially since we got the solar panel.

barryd Of course life was simpler and less stressful for all before we all had digital read outs of your battery status. If the lights were a bit dim you maybe thought about charging the battery. Now we sit and watch the meter or play with the MPPT Controller to see how many AMPS/Watts are pouring in (or out) of our precious battery. I even can tell how many Watts my TV is using or that it adds a watt or two if I plug in some USB speakers or that oddly in northern Scotland in bright sunlight in mid summer I get more watts going in than I do in St Tropez! Bonkers! Or maybe its to do with latitude I dunno. Either way its satisfying to see the precious power pouring into the van. Maybe its just me.

I think I have had about four or five years out of this current battery which I bought in Caen for about a hundred euros so if it croaks anytime soon I Reckon thats not too bad really.

fdhadi Excellent that chart Barry, thank you 👍

ob1 Don't forget that batteries in general can go well below their minimum discharge voltages without harm whilst under load. The correct reading is taken when the batteries are 'resting' (a couple of hours after coming off significant load without being charged). Or just like you and me having pulled ourselves together after a heavy night out.

Incidentally, for anyone interested in, or needing an insight into battery technology, I can highly recommend this company's webpage (aandncaravanservices.co.uk.) Their home page is a mine of information on battery technology covering Caravans and Motorhomes like you never knew existed!

Penquin Better safe than sorry Barry, yes, of course it does drop down to 12.1 but my concern level goes up well above "calm" into, "I am just going to turn these lights off"

We do have solar panels and they do work very efficiently here ( not surprisingly) and my "happy" value is usually restored fairly quickly....

But thanks for your concerns 😃

KeithChesterfield Why does anyone let the batteries drop that low?
A Solar panel and a cheap B2B and most of the year you won't need hook-up at home or away.
And save a fortune by not having to go on sites and pay for leccy.
