Now that's a proper battery discharge meter.......

It says 30 amp 125 volt on the one I have so your second pic is most likely the right answer and it’s AC ,it just don’t have the blades like your the one in your pic.cheersI think the third is a 30 amp load tester for 12 volt batteries an early ( ??) form of heavy discharge tester likely to be hand warmers at the end of the probe leads you clipped the volt meter to the battery with the leads and watched the voltage drop occur on the meter . Later Lucas ones were two wooden handles with a wriggly metal bar between the handles and were a pain to fit on certain 12 volt battteries if the terminals were not standard distances apart .
Like this but different in design

Ignore my thoughts on h fuse load test ..,
It's much more likely to be an American 125 volt 30 amp socket for screw in fuses View attachment 522761
This is a 125 volt bladed 30 amp fused switch but the principle looks the same.
Err yep, there's another parcel that's on it's way, should be here tomorrow.....Merely "getting"?![]()


I'm thinking of getting one too and I already have a NOCO oneI'm going to have to stop visiting this section soon, it's getting expensive......![]()

A bit likes "Vices".........Never hurts to have a spare.

You are a lucky man . Those two scroll forms are good money earners if you make gates. The square hobs are for the square hardy hole and the round ones for the Pritchel hole , does your anvil have both holes ?I found some nice stake anvils on marketplace but I’ve got a fair bit of polishing ahead of me.

RIP….here lies Matt and his junk!I look at it this way. We show an interest in something. We're doing something, rather than just going home each day, sitting down & wasting life in front of a TV. Our tools & quirks are us, & at least we'll leave some sign that we ever existed.
Make sure if you get the two handles heavy discharge tester tht the resistance bar can handle the biggest ampere discharge of any 12volt battery you're likely to encounter .Now that's a proper battery discharge meter.......
I've been trying to find a good one for years, even considered buying a new one at one point.....one of those and a Hydrometer is all you need to test lead-acid vehicle batteries.
Another package has just arrived, I had totally forgot about this one, could be interesting for possible unexpected night time callers.....I look at it this way. We show an interest in something.

They became obsolete/redundant due to sparking when stabbed on the battery terminals . HASAW people did not like that one iota especially if petrol fumes were present .Now that's a proper battery discharge meter.......

May they rust in peace!They did a 500 amp one, I was talking to an Exide Traction Battery guy years ago, and he stated they did build some 1000 amp cca ones, but I've never seen one or found any references to one.Make sure if you get the two handles heavy discharge tester tht the resistance bar can handle the biggest ampere discharge of any 12volt battery you're likely to encounter .
IIRC the 120 amp Lucas ones melted when slapped across 14.3 volt 220 amp NIFE battery
Now he has to buy an anvil..You are a lucky man . Those two scroll forms are good money earners if you make gates. The square hobs are for the square hardy hole and the round ones for the Pritchel hole , does your anvil have both holes ?
I000 amp would likely be a forklift or submarine battery tester ?They did a 500 amp one, I was talking to an Exide Traction Battery guy years ago, and he stated they did build some 1000 amp cca ones, but I've never seen one or found any references to one.
Or two anvils ?Now he has to buy an anvil..
