How healthy is this battery?

[Winnie]

Yes they are good. I worked for them for 14 years 🤣
I used to run 2 of them in my cars once. One for starting and one for the fridge. My thinking is that being the same battery they should charge equally having equal plates etc

I run a pair of these batteries and rate them pretty well.

Simpson ... *any* doubts about the battery ..... change it.

Any new battery will see you through.

24v for a Cpap - guessing it's a Resmed? - I think they get plugged into 12v or 240v & are converted internally to 24v. That's one of the reasons they use more battery power than some (conversion losses). The other is using a heated hose if humidification is needed.

G'day Cuppa. Yep Resmed. We got a converter for it so it'll run off 12v but yep it'll suck some juice, but all good.

Yep can't fault that logic. I'll check my crank battery tomorrow, I've not paid as much attention to that one.

Thanks for your help mate, much appreciated.

I think my battery journey is nearing an end, gee i've learnt a bit.

Right-o, I had thought they (Resmed) all ran at 24v & had internal converters. Checking, after your previous post, told me I was mistaken and that they do need a separate converter. Live & learn.

Ps: I run an Ultimate Extreme AGM as my aux battery.
110 ah and it is rated to 750 cca if I need it to crank via my vsr.
And it has dual terminals that make fitting all my leads easy as

And if you follow Roothy you will notice in his videos that he now uses them in Milo 2 and his support cars

So I went and tested my crank battery with the hydromoter this arvo. No cells are in the green, they're all in the half of the white stage closer to the red stage.

Are the those Supercharge MRV70Ls OK for start batteries? They have 760CCAs. Is that enough CCAs to start a stock 3L CRD Patrol?

[Yeti's Beast]

Ok if they are all even that means the battery needs a good charge for like 24 hours
But because of its age I would consider buying a new one anyway.
If the cells don’t get into the green after a charge it’s stuffed.
You would be surprised to know that the original battery only does around 550-600 cca
760 is fine, that the norm
I had these in my old 1986 diesel 6 cyl landcruiser
And it started fine

Don’t get sucked into the more is better crap.
Cars only need X amount to start and the extra does nothing. All you need is something that meets the manufacturers specs.
A deep cycle is another story but what a lot of people forget is to make sure you have enough power to recharge. Always remember you need at least 10% of a batteries capacity to recharge it efficiently unless it’s a Lead Crystal that’s need 30% according to them.
