Battery egg smell

[witzend]

In the spring I weighed in two batteries at the scrap yard - I got about £25 for the pair the replacements cost about £300 - so not such a good price.

What did you expect for 2 scrap batterys new price I'd have thought that was good

 

[malagaoth]

it was certainly worth doing but not worth scrapping a perfectly useable battery for which is what I took was being suggested

 

[malagaoth]

Here it is -

I'd replace all 3 as much better for them to be matched. Scrap battery's fetch a good price at scrap merchants

scrap three batteries two of which might be perfectly good for the sake of £40 at the scrappy - makes no sense!

Find out what state they are really in scrap the defective one(s) by all means but dont scrap good ones just so you can have the marginal benefit of having a bank of three identical batteries

2 of the batterys are 8 yrs old how much longer would you expect them to last.
I only mentioned scrap merchant because a lot of people take them to a recycling centre and get nothing for them

At 8 years old it will be failing due to age, and as you said you found dry cells this is because the lead is falling off the plates and building up in the bottom creating an easy electrical path which gets warm and evaporates the water creating the gas and leaving a strong electrolyte that creates the smell, by all means check out your charging system but I do not think it will be necessary. Do you need 3 batteries if your moving every day one would be sufficient unless you running all your household appliances through an inverter or planning to park up in one spot for a week with no other form of charging.

Do you need 3 batteries

That was also my initial thought but having been on this board for a while now I have learnt that many feel the need to generate and store enough electricity to supply a small village!

I have run (sans solar panels) for the last 6 years with a 135A/h battery never been short of juice despite a serious TV habit
(recently up graded to a 150A/h but only because it was as cheap a a decent 135)

The OP has chosen to have 3 batteries, that`s fine by me :dance: The way i see it it`s their motorhome and their money so it`s their choice :dance:

I read the original post and saw a question regarding a battery egg smell and not a question about how many batteries should i have

My batteries are almost eight years old and are as good as new, as far as I can tell.

unfortunately we are not talking about your "quality deep cycle batteries" we are talking about rockape's batteries one of which HAS failed after 8 years and it seems reasonable to me at least to assume that the other identicl battery will also fail.

what does as good as new AS FAR AS I CAN TELL mean?
have you had it checked?
In the spring my starter battery failed, one day it started the engine without problem then next it didnt and no amount of charging made it so it could start the engine. So on the monday (or whatever day it was) the battery was as good as new, as far as I could tell tuesday it was as dead as a Dodo.

A battery that smells of rotten eggs isn't worn out: it is faulty

I dont know the brand/type of this particular battery nor do I know how they typically fail - I am surprized that you apparently have this knowlege, did you get it by divine relelation or a personal message from Rockape?

I also read the original post where it states he is away in 2 weeks, I don't know about your personal finances but I know i would not what to be forking out 260 quid on 2 new batteries when the remaining one will suffice. Many will probably presume you need loads of battery power and don't realise that one is all they need, and think of the weight saving, it's probably cost 260 quid in extra diesel carting those batteries around for 8 years.

They hold charge, they have the same storage capacity as they did when new

how can you possibly know that unless you have checked?

I do have one of thise digital battery testers

they test voltage not capacity
At dud battery can hold charge whilst losing capacity - put a volt meter on it and it will read 12.8 put a load on it and it goes flat either immediately or in very short order, when I suggested getting them checked it was the capacity I was suggesting he get checked, have it charged up and then a significant load put on it - say 10A - a 110A/h batter 'should' meet this level of charge for over 5 hours before dropping below 12v

I know a great deal more about batteries than you do, clearly

said with conviction but no actual basis

To replace all three when he can probably get by with what he already has is beyond stupid.

which is what I have said, see my posts at #4 #9 #23 #24
#24 for example reads -
"scrap three batteries two of which might be perfectly good for the sake of £40 at the scrappy - makes no sense!

whilst I am of the opinion that Rockape probably doesnt actually 'need' 3x110A/h batteries Rockape thinks that he does and he knows his usage better than anyone so if HE feels that he needs 3x 110A/h batteries who am I (or you) to argue?
