What should a battery look like inside

[bigrockcandymountain]

Here is a picture of my surrette rolls s550 plates.  They don't look great to me, but i don't really know what I'm looking at.
They seem to perform as they always have.  Just looking for comments on the picture.  The cells all seem pretty even and bubble evenly when charging. 

I know, get a hydrometer and check the cells.  One of these days i better do that.

Ya that looks pretty bad.



Your picture looks great ,resolution etc.

There is one thing rings like a bell,

We have good amount on this topic that already exists on the database. I thought it was PTFE? is was food additive like MSG?

 search for DE-SULVATION. Your picture is good one for sulvation of the plates.

I think they should look like this.



Lead's good but black holes man..they'd never need charging!



Rolls wanna be Boilededd...If they're 5°C they oughta be seeing 63V absorptions.

When I was in collage we used a specific gravity meter to check battery state of charge there was something sulfuric, electrolyte. So dumping a battery was bad because it released all the calcium lead plates.

Ya so 4 months ago i turned absorb down to 59.5v from 60v because i thought i was using more water than necessary.  I put it back to 60v now. 

It is hot here now so they are more like 25c  so they wil be right on 60v
