Specific gravity of PbSO4 batteries - what it means.

I've uploaded the first batch of circuit diagrams into my Project Folder.

When you go to the Project Folder page and click on my Circuit Diagrams folder you'll see approx. half-size diagrams. Right click on any of those diagrams and select "Open Link in New Tab" to see the full size diagrams.

Then you may either download a copy or "Save Page as.." if you desire.

The 'loads' for the various Power Pulsing circuits may be anything you desire; a battery for desulfating/charging, a motor, a lamp, etc...

Regarding the 'cleaning' of the cells in the lead-acid batteries, some experimenters do drill holes into the bottom sides of the cells to flush out the shed plate material and debris. After draining the electrolyte from the battery first.

What I generally do to drain the electrolyte is, first, give the battery a good exterior washing to clean it up. Then I get a plastic rectangular container slightly larger than the battery to drain the electrolyte and 'whatever else comes out' into. Then I remove all the cell caps, pick up the battery over the top of the container or tray, then turn it upside down and let it drain until the battery is all drained out.

After the electrolyte has settled and cleared I then pour it slowly into a bottle for keeping until it's time to put it back into the battery.

All of this 'old lead' and sulfate can be collected and saved for recycling.

Probably the most challenging part of the procedure is figuring a way to repair the 'holes' in the cell bottoms so that they're positively sealed and leak-proof.

One way is to 'weld' a plug into place in the holes with a hot-air plastic welding tool.

Any others?
