I need to buy some new batteries, for our scotland trip next week &wondered whether its best to buy 2 x 110amp or 1 x 220amp is there any difference or reason to buy 2 instead of one.the 220 amp is slightly more expensive to start with, but 2 would need cables to join them so cost about the same.

these are the choices -

Any thoughts & has anybody bought instead of two?

There are a couple of influencing factors in my opinion.

1) Battery failure. With 2 batteries if one fails you have another to fall back on.
2) Battery aging. With 2 batteries they won't always age equally and you may have one pull the other down. This happened to me.
3) Space. Sometimes 2 will fit where 1 won't and visa versa
4) Cost. Price can be a factor?

My personal choice would be a single battery. No particular reason other than experience of 6+ years full timing. I would personally go for the best battery I could afford. Preferably AGM with VRLA valves. But these cost a fortune for good quality. My last batch lasted 8+ years.

Out of those 2 I would pick the single one purely based on weight.. The more lead the better is a fairly good guiding principle when it comes to battery quality.
 
Is your battery compartment easily accessible? Have you tried lifting a 220Ah battery? The one you are considering weighs 50 kg (not far short of 8 stone!). I could not manhandle that into an awkward location!
 
Space is not a problem i have moved the existing battery to under the bench seat, as for the weight i will get help
with putting it in.
 
I would go for the 2, much easier to lift and move, even if you only have to do it a few times.

Every joint is a point of failure so a single battery wins that argument.

"to under the bench seat" - is it vented correctly ?
 
My 250Ah batteries were 76KG. I managed to lift them in and out with a little bit of effort. I am a weedy computer geek who hasn't done any physical exercise since his early 20's... That said if you are older and have health issues then weight is definitely a consideration.

I initially have 4 of these batteries to give me 1000AH. Shifting them to a new van did take me a while as I had to take a break after each one :whistle::rofl:

It was originally under the front seat & not vented as far as i could see, also appears to be sealed with no where to vent from.

I could vent if required to outside.

I bet you did !:LOL:
 
What capacity battery is your charger capable of charging? That might influence your decision.

As its hymer i presume the recommendation is 180amps ish:unsure:

That's correct, assuming you have an EBL99 or 100. However, I had 2 x 110 Ah for about 6 years without problem. Now have 2 x 90 Ah.

If I were you I'd get the big Bugger and if I were your bestest mate I'd offer to pop up and give you a lift with it.

  1. I'm not you
  2. Speak nicely to @ROB1CHELSEA1 :moon2: :moon2: :moon2:

I have an ebl99, why the change to 90 from 110. ?.
 
The 110s were Elecsol - no longer available. Now I have Varta and 90 is their low profile model that fits; less than 200 mm high.
 
I did read that you have room, but have you seen they are 200mm longer, they would never fit in my locker (y)

Mind you making battery connections is not rocket science and 2 batteries gives a certain level of power redundancy. As for venting what would you suggest?
 
I would go for two especially if using an inverter as drawing a high current will be split between them. So for a microwave drawing 150A there will be a draw of 75A from each rather than the lot from a single one. Leisure batteries, unlike starter batteries, are not really designed for high currents.

Thread Hijack.

Going to put one in my mini camper build

Its a slow work in progress as long as its ready for September i am happy. I want a pleasure battery and just using a manual switch but as i only want it for the odd lights at night and a car stereo in the rear would a small car battery be OK? Something around 75amps. I was thinking a Motobatt motorbike battery but not sure if van alternator would kill it.

The battery will only accept what it needs - size of alternator has no effect.

I don't suggest anything but I am pointing out that if it is a battery that vents then you don't want the possibility of hydrogen building up in a cupboard with electrics in it as could happen with the post that said "I moved the battery from to........". Some batteries have a vent pipe you can direct outside, some don't.
