Another Battery Question

If I may add to this:

12V in the N70 size is 306L 170W 210H which takes a max of 105Ah AGM.

The next size up is 330L 170W 210H for a max 120Ah AGM.

Stay away from sellers stating 125Ah or even 130Ah in this size.

The battery weight says it all, there's 0.3kg/Ah.
E.g. AGM batteries advertised as 130Ah, these would hit the scales at 38~39kg if the capacity were true.
Plenty of cons around flogging "130Ah" ones only weighing 31.5kg in the 330mm container (which would be a lot closer to 105Ah or 110Ah).

BATTERY VALUE...I purchased a 130 amp in the 330x212x173 configuration and 31.4kg. Are you saying that no manufacturer produces an agm in this size at 130 amps? If this is the case I will quite happily inform the seller(sellers) that they are fraudulently selling batteries and demand my money back. As will many others, I suppose.

That's precisely what I'm saying.

You can start by asking the seller to produce a load test as by AS4029.2.

If you want to escalate the matter you need to add some beef to your demand.
A verifiable third party test result is something you can use when contacting Consumer Affairs.
In Qld, such a test costs 2~3 grand.
The seller knows this and is betting nobody will be willing to fork out this big in order to make him stop acting fraudulently.

Trouble is that the manufacturers are the ones making the claim. Fullriver, SSB, Universal Power, and many more battery brands advertise these batteries as around the 20-130 amp mark.

Generally, battery manufacturers do not fudge the performance data of their product for obvious reasons (litigation by competing manufacturers within the same jurisdiction).
But the importers and/or sellers abroad frequently do, in their quest for increased market share.
The importer can approach the manufacturer, in terms of what goes on the screen printed label in his country.
Complete specs sheets can be "re-designed" with fudged performance figures, and the manufacturer couldn't care less if done under another trademark in a foreign country.

But all is not lost, because battery weight remains the biggest giveaway, and it can't be changed unlike the screen printed label.

Here are some battery weight examples from the Fullriver specs sheet:

HGL100-12 328L 172W 214H, 30.4kg, 0.304kg/Ah
DC120-12 331L 175W 214H, 36.5kg, 0.304kg/Ah

If you compare this to 0.24kg/Ah of your battery, obviously something doesn't add up - or Fullriver and the likes don't know how to save lead in a given battery size.
