My battery seems to have no ID. Anyone any idea what it is? As you can see it's a 180 Ah AGM, but that is all I know.....

It's probably printed on the sides which we cannot see and I cannot even magnify the picture? Need more info! :unsure:

As far as I know, there's not many 180 Ah batteries?

Nah, nothing on the sides. You have as much info as I do..... It's in a Pilote if that helps, and I think it's the orginal.......:giggle:

Not a clue on that one but it has those horrible pressed steel quick release terminals they need to go in the bin with the AGM battery.

Well, I think the jury is still out on the performance of this particular AGM battery. I have my suspicions, but I'm still gathering evidence for a conviction...... I did wonder about those terminals. What's the problem with those, Lenny HB ?

I think you will find under the covers they are pressed steel, not very good for conducting electricity, can't beat good old fashioned solid brass ones.

They can also come undone on rough Scottish roads leaving you wondering why you have no power 😡

IF it's original, why not ask a Pilote dealer, you have the chassis number I presume? :unsure:

What more do you need to know? Is it duff or are you just curious?
A replacement needs to be the greatest capacity that will fit in the space available and has terminal posts compatible with your ('orrible) connectors.

Its a Special Charging Rates Apply Probably battery, or otherwise known as SCRAP

Sorry to be cryptic. I'm not exactly happy with how quickly it seems to discharge. But I'm only going on the crappy control panel display which I doubt is very accurate. If anyone cares to comment, I have the following information.

Removed battery from the van. Reading with a voltmeter was 12.76V. Charged it for 24 hours. Left it for 2 hours, then read with voltmeter. Reading of 13.00V, next day 12.96V, next day 12.94V, next day 12.93V, next day 12.90V. Got bored and replaced it in the van. Does that seem OK?

Yes, the off-load voltage is O.K. but the battery can still be knackered. The voltage may drop considerably as soon as a load is applied.

Looks like a standard truck battery size to me.

Yeah, that seems to be what happens. I guess I'll know more once I've fitted my new Victron BMV 712. Cheers for that thought.

Best way to test it:

First charge the battery fully and leave it to settle for an hour then:-

For example if it's a 100a/h battery load it with a 5 amp load and run for 5 hours, this will represent a 25% discharge. (adjust load/time to suit the size of the battery) For your 180ah battery the C20 rate would be a 9 amp load.
Disconnect the load and leave to stand for at least 30 min then measure the voltage.
Repeat the test and you will have discharged the battery to 50%.
You can repeat again then it will be 75% discharged.

It looks very much like the battery that came with my ambulance, made in America, it was flat when it came and I couldn't get another one like it so swapped it for two ordinary 100 amps.

Ah, that looks like a smart way to find out what is going on. It'll take some setting up though, as the van is in storage. So I need a 2000W load?

That's interesting, but I can't imagine a French made van would have an American battery. Unless the previous owner was into long range sourcing and swapped it. :giggle:

Very few of the batteries sold in Britain are made by British companies?

That would kill the battery, 2000 watts is 166 amps.
You need approx 110 watts.

I'm struggling to think how I would get a 110W 12V load..... I expect it's obvious.

Headlight bulbs?

I use this home made load device for testing 6V classic m/bike11Ah batteries........both filaments are connected. (45W and 35W = 80W)
