Lead carbon batteries

I installed 4 x 100Ah of these Newmax a year ago. Can't tell you anything about them except they are good value and doing what I expected, so far.

we have come across lead carbon batteries and they offer 3 yr warranty and recharge quickly.

More advertising BS the gullible will believe.
Where is the proof. Lead carbon, lead crystal, lead BS
Sadly yet another advertising con
What makes them recharge quickly compared to any other LA technology. You have to love the advertising that hood winks people into technical impossibilities. Supply NATA certified lab results and we may believe it if paid by other than the manufacturer.
Lithium now works out 1/2 price old technology lead acid.

There are many variations on lead acid battery technology. Some are very significant, some differences are minor.

Crank batteries are different from deep cycle batteries.

AGMs have particular features compared with flooded lead acid batteries, but that does not make all AGMs the same either.

From my perspective I purchased these batteries because they appeared to offer very good value for my money for the job that I need them to do. Whether they provide that value or not is yet to be determined and won't be determined for some years yet, but one thing is for sure. I will be the judge of that, not the manufacturer, not the supplier and especially not you.

Why try and address rubbish instead of the post. Everybody knows about the different types of batteries and doesn't need such a basic lesson.
The issue is the unfounded claims made by sellers with no scientific or approved research data.
Thankfully I am a double certificate engineer and don't post like some that just have to see their name up in lights. Especially lacking in basic technical and scientific expertise and knowledge like yourself.
Sadly to much information is posted here as fact with no basis. People make purchasing decisions on the poor information posted. Leads to people purchasing equipment which doesn't bring about the best result.
Because you are gullible to advertising, doesn't make a product good or value.

Goodness...... and your posts have been so helpful to too. biggrin

Thank you for your great wisdom and insight.

I have found often, lived experience is far more reliable than bits of mouldy old paper certificates. I also have bits of paper to my name in many fields but always read what Peter and Margaret have to say and some others on here. I grant you there are not many but enough quiet achievers

Why would you not accept a test report from a NATA laboratory if the test was (as is usually the case) paid for by the manufacturers of the product?

As you have raised the issue: exactly what are your qualifications?

Mike there are plenty of experts on here with no qualifications and double certificate engineers with very little expertise maybe Monica is one of the later

Hey people ease up on the personal responses and get to the real discussion. smile

Buffy my personal opinion of hyped new technology for something like a battery that you hope will last for years is this. Let the other people do the testing and see how they go. Stick to the tried technology that you know works well. Ask around. If it is so new you cannot find anyone to ask then do not buy it now. I believe Peter has researched his purchase well and is happy with it. wink

The difficulty is that the internet and overseas suppliers has made decisions harder. So stick with what you know works well and expect to get your moneys worth. Batteries from a quality supplier are good. hmm Some warranties are not so good either and 3 years is a short life ! In three years time will the supplier be basking in the Bahamas and not answering the phone !

Not too much research. biggrin

This is my third set of house batteries in the OKA.

The first were Fullriver HGLs that were replaced after 5 years while on the road 8 months each year.

The second set were Fullriver DCs that were replaced after 9 years of less intensive use.

I believe the secret to getting good life (relative to their use) is to ensure that they are charged properly (according to the manufacturer's specifications) and fully on a regular (almost daily) basis.

I would happily have bought Fullriver again, but the prices have increased quite considerably compared with others on the market and as batteries are a 'disposable' commodity, price has an important part to play in the purchase choice, along with the risk of choosing something different.

400Ah for $1,000 seemed like a valid choice on this occasion, irrespective of whether the claimed special features of these batteries are valid, or not. It is of significance though, that the recommended charge voltages for these AGMs are lower than for the Fullrivers that I am used to.

So far, so good.

Cheers,

Peter

Me thinks Monica, is a bloke, and that bloke has a chip on his shoulders especially with this forum, and anybody, whom would like to offer up their opinions, view points or their experience. She/he is coming across like a troll, and trolls are not wanted in this forum. If you can't make a sensible comment without making assumptions which has no basis in fact, and also wish to belittle people, I think it would be better if you leave and don't come back.

Hi Peter.

Of interest mainly because one day in the near future we are going to need to replace our house batteries,

Our 2012 caravan has one original battery, I added a secondhand one of the some age, contruction and a similar secondhand battery as a dual battery in the car, all similar spec, 100ah deep cycle. All doing as we ask with 340 watts of solar, no petrol generator, no 240 battery charger. All has worked fine for the last 3.5 years. We get about 3 to 4 months of touring in each year with the caravan, rarely connecting to power and then its only for the 3 way frig.

I have tried to read the reviews but it is all numbers, eg. they say the battery is lighter then other batteries but then further down the page it reads just as heavy as what I am using.

Our batteries are about 34kgs each. I would consider something lighter in weight if it was economical with out loosing performance.

Are your batteries physically the same size as your previous and was it just a dollar thing that attracted you to change?

Frustrated.

Radar, These batteries were the same size as the ones that they replaced and about the same weight.
Weight is a good estimate of their capacity. There is no such thing as light lead, so if they are lighter they are also smaller capacity.
If you need lighter you will need to spend more and buy lithium.
Yes, the price of these was attractive.
It is clear that many products with a good reputation cost more. Sometimes that is because they are better. Sometimes you are paying for the reputation. Conversely, some cheaper products are cheaper because they are not well known, not because they are inferior.
The trick is to know which is which :)

Peter
