These are my experiments to convert a new never used
lead battery to an ALUM electrolyte and see how the battery works.

Enjoy !

yes mr administrator.aluminum sulfate releases a certain amount of sulfuric acid in solution.you can even make a leadacid system with epsom salt,magnesium sulfate,but the voltage comes down due to lower acidity.

New battery load tests from today:

If you have any tips how to effectively test the battery please let me know.

In this moment I don´t have many measurement devices, so I need to
buy a bit more equipment to test this more throughfully...

I still need a 12 Volts power meter and a battery power meter tester.

What test devices would you propose ?

Many thanks.

Regards, Stefan.

P.S. Any idea how I can modify my inverter to get it to run on lower voltages ?

Hello, I am an engineer working with battery charging technologies here in Australia.  I can give you some tips.

A couple your questions -

Inverter modification?  Dont bother with that it, it is too complicated if you are not trained in and are asking the question.  Im not sure how many volts your battery is putting out but I would suggest you buy something like this DC to DC converter, it is German made and a very good brand.  It is also VERY efficient.  IF the resulting voltage is then too HIGH for the inverter then you can use a zener diode circuit to clamp the voltage at 12-13 volts.

How to load effectively battery?  Essentially loading battery is shorting it with enough load so you can watch how it responds and differentiate between good 'deep' charge or surface voltage charge that fools the meter.
I have some very small Gel lead acid battery here that are only rated at 12v 1.3AH.
You need to work out your capacity of battery so you do not draw too much load or charge too much.  On this topic I think you are putting too much current into your battery.
With the little battery I have here it is unreasonable to make th load too big like a 12v 50 watt lamp because it will crush the voltage level and drive below 12 volts quickly.  So I use a 10 watt light and it should hold nicely above 12 volts without sinking rapidly.  Your question is a little bit "how long is a piece of string"  :-)

For your battery capacity I think a 12v 50 watt halogen light globe should work nicely as a load.

All the best

test devices..i would suggest to lead the cell into electrolysis tanks in series with 2 carbon electrodes/cell and watch rate of bubbles formation.aprox 1.8 volt required/electrolysis unit so you can roughly estimate total volts and rates.dont knw much bowt inverters mate,cant help there.
