Battery replacements which to go for??

[Merry sheppy]

Hi I have two numax110v xv31MF batteries which need replacing. I’m looking at power plus 110v with 5yr guarantee . But not sure what I’m looking for

The XV31F is 105Ah not 110v so maybe you're looking for the wrong spec'n?

Something like this one...........

 

[Merry sheppy]

Yes that’s what I have now but wanted to get new ones with longer life guarrantee , just wondered on any that people found reliable

Numax batteries are made in the Hankook factory in South Korea.

These are 130Ah so a little taller - check they will fit

My Numax batteries were 9 years old when I replaced them for lithium. They had lost some capacity but were otherwise going strong. On that basis I wouldn't worry too much about the length of warranty.

 

[Merry sheppy]

My batteries are 6 yrs old and won’t run the fridge lighting etc for more than 24 hrs . I had them checked and was told the capacity had dropped but would probably do max two nights. We often do areas like the new forest and don’t have hook up. I’ve probably been unlucky they are giving up

 

[Spriddler]

Yes that’s what I have now but wanted to get new ones

Yes, I realised that but you may be having difficulty (and as you say: not sure what you are looking for), as you may be looking for a 110v battery (the 'V' is voltage which is not the same as 'Ah' which is the battery's capacity). Your current Numax are 105Ah capacity.

Did you have to change much to go onto lithium ones

 

[mofurt]

As a general rule of thumb, for me if a battery is more than 4 years old I consider it to be end of life and likely to fail at any time. Usually they last longer - sometimes much longer - but at that point I don't begrudge replacing them. At 6 years old I wouldn't think twice.

Maybe adding solar would be more useful to you than lithium, pound for pound on investment? Depends what roof space you have available, if you are comfortable doing electrics yourself, and how you use your vehicle. Summertime for extended periods with no hookup and no extended driving to recharge on the move, solar is likely to be better for you than more expensive batteries if you can only do one or the other.

Thanks for that cheers

Varta EFB 95ah looks good

I changed my solar controller to one with a lithium profile and added a B2B with a lithium profile.More recently I bought a 2nd hand lithium charger for use on EHU but I don't expect to use it often and I probably could have got away with my standard charger but I wanted to ensure that I looked after the battery well.
So it all adds up cost wise but I fitted it myself which saved a fair bit

I don't know where you are looking for your new batteries but I have always had good service from Tyna Batteries.

If you've not purchased them already then please consider going for a lead carbon battery, they have many advantages over lead acid and can be viewed as a halfway house between lead acid and lithium.
They can be cycled many more times than lead acid. lead acid typically 200 cycles, lead carbon 1200.
They can be left 50% discharged without internal sulfation occurring which is the killer of all lead acid batteries.
They have a lower internal resistance so the bulk charge phase lasts longer giving quicker charge times.
Their charge efficiency (how much power is put in compared to how much you get out) is much higher than lead acid. (lead acid 85%, lead carbon 95% lithium 97%.)
Ultimately they are a much better battery, mine is 4 years old and still like new, powering a toaster/hair dryer/ microwave/ hob via an inverter no issues.
They don't need any modifications to the existing charge system, they just drop straight in too.
Leoch do a good range and they can be had at Tayna with a 10% discount to CAMC members. The AGMs (what I have) are the cheapest, the gel range have slightly better spec and can be laid on their side if need be but cost a little more.
Hope that helps, Merl.

Thanks so much for the reply, very helpful and I will look at these

Yep, I have 2 of these topped up with 400w of solar, never any issues, previously had 2 x 125ah that lasted just over 5 years
