I have a bush block (in an old fishing village) I am cleaning up, in among broken beer bottles and fishing net,
I found these; see pic. Could be related to commercial fishing boats? Thanks
It looks like it was something either over or under a cluster of small batteries, maybe AA up to D size. I can't tell from pic because there is no size reference.
They might have been simply in storage or they might have been used to power something, although it would be unlikely to have so many connected in parallel. Normally you would just use a bigger battery.
So my guess is they were just in storage.
The remains of one of the batteries can still be seen in the pic foreground.
The centre rod is the centre electrode. If it's very old it will be a black carbon rod.
These old zinc - carbon batteries had a very corrosive electrolye in them so when they got old and leaked they could chew into whatever was surrounding them.
Approx size of individual part is 90mm x 25mm (see circled pic)
Im with buster and pweedas on this one Looks like a box of batteries.! Carbon rod kinda gives it away. Think the green maybe a copper vent ball?
Just don't stick it on a fire i doubt that its unexploded ordanance else it would have more copper and lead .but you never know. Just be careful how you handle it.
So handle with care and dispose of at tip battery drop off, correct?
I wouldn't trust an internet troll Muppet like me.
Be on the safe side.

Actions on finding a suspicious item
If an Item is found - DO NOT TOUCH IT. This includes making any attempt to move the item to a 'safe' location.
Mark the location so that it can be found later. Coloured tape or paint make easily recognised marker material.
Inform the property owner, park ranger, prime contractor, site foreman or site supervisor of the find.
Inform the Police that a possible ammunition item has been found. They will instigate a request for Defence personnel to attend and dispose of the item.
Possibly a battery pack made up of an array of small batteries? The carbon and anode give it away me thinks.
Approx size of individual part is 90mm x 25mm (see circled pic)
So that would make it a cluster of D size batteries.
So my guess is it was a box of D size batteries for a torch or something similar.
Probably it was a box of new ones which got forgotten, or sometimes people saved up old ones, because those old type regenerated a bit if you left them for a few days. Then you forgot about them and discovered a year later, they had leaked everywhere and threw out the whole box.
The same structure went right up to the old 1.5 volt PMG sized battery, about 3 inch diameter and 9 inches high, which were originally used for telephones but then went into wide use to power the filament circuit in old valve type portable radios in the 1930's to the late 1950's. They were made obsolete by transistor radios and so after that were used for glow plug power supply for starting model aircraft engines. Even that use was made obsolete by the small ni-mh batteries, so I don't know if they are even made any more.
So handle with care and dispose of at tip battery drop off, correct?
Nah,. you can just throw them pretty much anywhere. The corrosive nature was not all that toxic from recollection.
I think it was ammonium chloride or something like that.
Most modern batteries are not toxic because of the electrolyte, it's because of the heavy metals in them, particularly cadmium.
Us kids, (me and my mates) used to pull the old batteries apart to get the carbon rod out and then use the carbon rods as arc welder elecrodes to make really bright light. It was spectacularly bright white and made the whole workshop light up like nothing else. (use a mask if you decide to try it or you will go blind.)
Thanks very much. I also posted the same question on the grey nomads forum and got this reply;

grey nomads are a great resource for technical questions.

My guess is old corroded batteries too.
They used to be made in all sorts of sizes and shapes. square, rectangular, cardboard exterior with copper strips for contacts on the top or sides.
The ones in your pic. don't look like dets or TNT boosters, even though the sizes of some are very similar.
No one in their right mind would store boosters with dets inserted, it just doesn't happen.
Detonators are manufactured based on an aluminium tube, very rarely you can find dets made of copper - but I haven't seen any since '89, and those were made pre WW2.
The rods in your pic. look exactly like carbon rods from batteries.

They look too long to be batteries???
They look like 'F' size to me.
Except I've never came across any batteries with zinc anodes on the inside.
They all had zinc cases and carbon anodes, with pressed on copper tops, which is the green buttons you can see in the pics.
If you scrape the inner anode it will be black.
Maybe in the northern hemisphere they reversed everything and used carbon outer cases and zinc inner anodes? ![]()
