Battery condition

[selamatg]

Hi All,

I start this thread to talk all about battery condition (specially Lead acid battery)

I have try charge with SSG and Simple Solid state Oscillator.
most of the battery in charge side is death battery that I found from around of my house. Some of them is back to live. but some of them still stay in previous condition or in other word cannot hold the power.

The ones Battery is too fast the voltage rise up on charging and when putting load very fast drop too...that even I ran many cycle still with same result. possibly one or more cell broken already ..I guess.

The other battery, The voltage doesn't want move up..let say maximum 12V on charging even many hours on charging.

I have question,
How to check for the battery recondition able or not?
What the maximum/save voltage on charging?
What the best way for the battery plug position (stay tight close, lose other open on charging).

Many thanks

When to keep a battery when to pitch...

Hi,

I have spent alot of time asking myself this question. Much depends on your supply of dead batteries and what you are attempting to accomplish.

So far I am finding the best charging with the SSG to be about 18-32 V and from 1 -4 amps (depending how many coils I have ) for 12V batteries. I think the key is to do it many many many times. However, I have found that on some of the bad batteries you do it for many times, then if you let up, the go right back to the bad state they were in before... Sometimes the electrolite is corrupted with gunk....

I guess for all the time I have dumped into the bad batteries if I was to pay myself $5.00 an hour I would have several brand new batteries for the time I have spent trying to get bad ones back to life.

I have just finished getting my Solid State Bedini from page 46 of "Free Energy Generation" going last night, and I have 3 bad batteries that I am looking forward to see what it can do with them.

The tests to see if it is worth the time is to charge with the SSG, and then load test. Do this about 8 times, and document the changes of the battery voltage and how long it can stay up under load. If it does not improve any after this time, it may be time to change to an alum electrolite, or check each of the cells voltage ( with a coat hanger ) to verify charge ( also can check the acid with a meter as well )

It is about time. Is it worth spending this much time on this battery? Do I have more time than $? What will I use this battery for once recondition anyway?

Some batteries cost more to recondition than to buy a new one. And there is worlds of difference in the quality of the plates of the batteries from one to the other...

This thread has been stagnate for a while so here is a new question.

I have two 12V 135 Ah batteries that were given to me and are only a year old. The owner said that they were both working perfect one day and then literally the next they both die under the smallest of loads. ie 300 mA. They are custom made true deep cycle batteries with a tubular plate design and the last batch lasted 4 years with daily complete disharge and charges. Everything I have tested, cell voltage, specific gravity etc reads good, but they just die the instant they are loaded up.

I have no idea what the problem is. (something simple no doubt )

Cheers,

Steve.

Hi Steve,

Sounds like they are sulfated to die under a load like that, but
I'm only guessing. I don't really know.

Custom made? Can you take them apart? Is there a removable lid/top?
Or do they look about like any other battery does with fill caps?

If you can take them apart or even if you can't, you should dump out
and save the solution, but not in an aluminum turkey pan (I made that mistake once).

One try the charge method at the bottom of this post and don't rinse the out
AND/OR
So you can really see what is happen, but don't tell the lady of the
house what you are doing.
Go to the tub and rinse it out and see if you get any gunk/crap out of them.
Now, MOST people will tell you to only use distilled water, but I would have
used over eight gallons of distilled water washing out one of the batteries I did.
So I figure it this way, the battery is worthless now, How much more
worthless can it get washing it out with tap water? Besides after I washed
mine out with tap water it had a higher voltage with no solution in it.
Use a gallon of distilled to rinse out the tap water afterwards.
I have to also say the battery was never "recovered". It did better than
before being cleaned and charged but was still worthless.

If they both went bad at the same time it could have been a sudden
jolt that knocked a bunch of flake off in both of them at the same time.
Both having a short at the same time isn't likely.

After all that, you have a cheap way to try and recover them via
the $6 radio shake relay charger circuit (see Imhotep's Radiant Oscillator instructional)
and you can use a cheap around the house transformer instead as the source instead of a 12v battery.

You can visit Imhotep's forum and read the battery recovery postings there.

Let's us know what you find out.

Hi Randy,

A sudden jolt is the most likely cause as the batteries are used in kids electric cars.

Unfortunately the tops are not removable (only the screw caps are removable). When you say to "keep the solution", should I put it back in after rinsing the batteries out or mix up fresh stuff?

Cheers,

Hi Steve,

I have same problem before, with 2 of 12V 60AH lead acid battery.
What I did, drain the current solution then fill up with destilated water then charge using low amp power supply for one night.

The next day I drain the solution then put the previous solution back.
Then I using my SS charger.

The result : one of them back to good condition but the other still same condition...

Hope that will help.

Steve,

Again I don't know. A major single time drain on the batteries will kill them.
The jolt idea was thinking if the batteries were normally stationary and
generally worked fine, then stopped.

In either case, a major drain or jolt, you might get them back.
The rinsing them out is to see if it is due to build up at the bottom of the batteries.

Yes, reuse the solution out of the battery. Drain them, saving the solution.
As you dump the solution out you might see crud some out.
You can use a coffee filter to filter the solution after you have dumped it out.
Don't try to filter it as you dump it out. If the solution is cloudy or chunks or
specks of stuff comes out, then a rinse might do some good.
Depending upon how slowing you dump out the original solution, you might
not see anything come out other than the solution.
You'll probably see more stuff coming out than when you initially
dumped the solution out because initially you are pouring the solution out
slowly to keep it. During the rinsing you are trying to dump the contains of
the battery out as fast as possible, which allows for more crud to exit.

You can retry a normal charger or a radiant charger.
With a radiant charger you are not going to see the batteries bounce
back after just one charge.. it generally takes many charges and drains to
get them back. The Imhotep's Radiant Oscillator can be used as
a battery charger.

Let's us know what happens

Thanks Randy,

I drained one of the batteries yesterday arvo and a small amount of flake came out, but over all the electrolyte looks good. very clear. I'll be flushing the battery out today, but the closest thing to distilled water I have is rain water from my tank. It's filtered for drinking so it should be better that tap water alone. The only awkward thing is trying to move a +50Kg battery into a good position.

Anyway, I'll take some pics as I go so that others can see what I do. Right or wrong.

Cheers,

Steve.

Minus Voltage

Hi All,


My 120AH battery showing Minus voltage under load (yes Minus ), anyone familiar with this problem?

At rest voltage showing 12.89V, then I use 60 Watt lamp as load, suddenly voltage drop to 9.30V, I try keep load to 8.80V (190 Minute).

I try check the voltage for each cell under load (one of them showing -1.45V)

Regards,
Selamatg

An electrictian told me once that if you get a battery that reads negative, charge it for a short time in reverse and that "should" sort it out. But if yours is only when it is under load then I am

BTW I forgot to take shots of the battery while I was flushing etc. However I am pleased to report that it has now been loaded down with 50W for the last 4 1/2 hrs and the voltage has not moved from 12.12V (12.6V when it was resting) Looks like it's on its way back. Just have to do the other one now.

Cheers,

Steve.

Thank Steve for your reply,


I'm sure the problem with that battery is only for that cell, So I really need to know if any idea to fix the problem then I can use the battery.

And good to hear your battery give you good result
