Can anyone tell me what kind of battery this is?

These batteries (6 of them) have no marking.
Can anyone tell me what kind of batteries they are?
Also one of the fuse blew and I have no power in my skoolie. Fuse is buss and won’t come till Monday and I can’t find it in stores. I think the setting are wrong but I have no idea. I reached out to a van building company that work with victron to ask if they can check my settings. Always something.

Looks like there is a QR code on them that you could try scanning with your phone.

It’s not a QR code. It pulls up nothing, I’ve tried. It was the first thing I tried.

 

[Slapdash]

Are there any other markings in the case, like a serial number? Maybe stamped in the plastic, possibly on the bottom?

 

[Roxy Moon Bus]

There is no markings anywhere on any sides.

Those are DIY Batteries. No brand.

Best you can do is hook a multi-meter up to them and get the statistics.

MOST DIY battery kits like that are decently high quality so unless one of them is bad it shouldn't matter.

Test to see if it's a 12v battery, should be at or near 13.8v if new, or nearer to 13 if used and good, below 13 if going bad after a charge.

There's no good way to test CCA's unless you build a resistance chart for measuring with known good batteries with listed CCA's, and compare. The internet does not seem to have such a chart in existance, I've looked, but in theory if you had a new battery with listed 900 CCA's and you did an ohms test from terminal to terminal, and it outputted a value, that value would be a good resistance value for a 900 CCA battery, and then you could compare your batteries to such a list to get a rough idea of what your CCA's are for those batteries.

This doesn't help you of course because I have no values to give you and you likely aren't going to go out and buy various sizes of batteries to make your own chart, in regards to CCA's of the battery.

I wouldn't worry about the amperage too much. Put two of them together and see if the bus will start, if so it's enough, You could Add one extra battery after that for better amperage storage, and allow for longer cranks.

If 2 batteries isn't enough for the bus, then it's likely got quite a low CCA rating.

You are amazing, thank you for the response. It’s the house battery so the battery connected to the solar and inverter. It’s 12 volt, I did a battery check last night before it was full charged so it’s not accurate but the battery checker asked for the type, I choose lithium because that’s what I was told it was and then it asked to choose cca, IEC etc.. I choose IEC cuz and then it asked for the amps I choose 100 amp and then it calculated but it could be incorrect.

This is what the victron is showing now.
Also no matter what setting I do, ignore ac input and prioritize solar, the solar still won’t change the percentage on the inverter. It will only start going up when connected to shore power no matter what settings I try.

13.4v is a healthy battery still. What are you trying to accomplish other than determining the CCA? The amps usage on the victron is battery current amps used, not total capable CCA's.

I'm not sure the inverter only cares about the correct voltage and amperage used which looks to be a 12v inverter. 13.4v x 31.33amps = roughly 440-460 watts. So that's what you are drawing, not what you are putting in from solar. (or is this menu from your pic the incoming from solar?)

Also solar amperage is always much lower than a battery bank (or shore power)
