UPDATE .....
I started this project in late 2021, i have other projects so this has been delayed, but finally i am getting their, oh yea.
The Case of the NEW MODERN PLANTE lead acid battery.
Over Christmas the case has been undergoing fluid testing. All good.
Remember folks, this is a project and concept that will be official published, tech drawings, designs and jigs design, and loads of colour photos, for anybody on this Planet to make their own.
Designed and Now making the steel moulds so the internal plate joining lead bus bars can be easily constructed/cast.
Questions from David, and my Answers.....
Q.
Will the plate assembly be easy to lift out to clean sheddeed material from the botton or will the thickness and construction of the plates avoid anything falling to the bottom?
Yes, the assembled plates will be easy to lift out, as the the top of the battery will be removable. The negative and positive terminal post will be 10mm stainless steel, so undo the 2 stainless steel nuts and shims and the case top just lifts off after the 12off top 4mm stainless bolts are removed. The top is sealed with a tested silicone that can be cut with knife.
The plates sit on the case bottom strips that are 25mm to the sump. They also sit on the intetnal lip and the lead bus bars. These plates are solid so the lead dioxide active surface is formed as the battery is worked. They are NOT a grid matrix with a impregnated lead dioxide.
Q....
Do you see any advantage in having an air or fluid pipe going to the bottom of the battery for electrolyte circulation as I have seen some commercial batteries or do you believe that proper charging and equalising takes care of that?
No, each of the 13off SOLID rigged plates are in a thick geoyextile felt, non woven, sock. I have allowed 5mm internal clearance for the plate sides, and the plate faces are not tight against each other.
Its a proportional relationship between amount of lead plates to Acid required and circulation.
Everything is possible, just give me time.

Battery fully assembled, 10 feb 2025.
Awaits acid.
Setting up the test electrics and dump loads.
Battery weighs 46kg with no fluids.
Polypropelene bucket when testing the battery and if it gets hot under tests.

I have to build up the lead-dioxide on the surface of the 13off grooved lead sheet plates.
This needs to be done very carefully at the begining of the process.
Max charge voltage will be 2.47v at 12 amps at the begining of the charge discharge process.
Once the amp hours start to improve then i will increase the charge amps up to about 35 amps and discharge rate will also increase as i change the dump load to a 1kw load then 2kw load.
I will be studying the data output very carefully.
Charge voltage will stay at 2.47v.

Wow Clockman, that is definitely a long term project. Great to see the progress and it will be interesting to hear the results of the forming and how the cells go.
Have you built all the cells or just one so far?

Each one of those batteries, contains 12 active 2v cells, each cell has a very large surface area.
The 12 cells are parrelled to give good amp hour ratings, and those will be found when i start testing.

Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
