The different ways to charge a battery

I also have purchased the smaller Universal Charger, which refurbishes all types of batteries. I started the large battery project with it, but because it was intended for smaller batteries I thought I should use the industrial types to speed up the process.

The Universal charger has given new life to my collection of automotive batteries, as long as the cells have not swelled too much from winter freezing. I have dozens of 10+ year old refurbished batteries: 26 were 7V Prius "BAD" NiMH modules that I got online, which are ~20 years old.

I accidently revived a Lithium razor battery thinking it was NiMH, which is not recommended, however, the charger was very effective nonetheless.

Every experimenter should have something like this, to keep ALS batteries desulfated and NiMH at full capacity. If you have not made your own radiant energy battery charger, consider getting something like the RC-1AU Universal Battery Charger.

Latest development for charging the industrial batteries in my previous post:

I was able to bring back one battery, so it can be charged by the Trace Inverter/Charger.

However, the other battery had more frost-heave damage, and has gone through several refurbish recycles, losing voltage, instead of gaining voltage.

Note: The industrial 2V rejuvenator has been used on several of the cells, but the over-all voltage would not come up.

One half of the 24V battery started at 8V+ and, after cycling, reduced to 4V. I checked each cell and most were around 1.9V to 2V. One cell was MINUS 4 Volts!

This is the first time I have experienced a negative voltage cell, which a battery scientist insists cannot be reversed:

Most likely someone has charged the battery mistakenly in reverse. A lead acid battery has lead materials in both electrodes that can polarize in the opposite direction when charged in reverse. Attempts to correct the situation by charging in the correct direction are fruitless because a key organic ingredient in the normal negative electrode will have been oxidized during the reversal. Furthermore, the chances of a short developing during a reversal is high. The battery cannot be recovered to a well functioning state.

I am determined to test this statement by discharging the cell and applying a positive pulsed charge using my Universal Charger, which is much weaker than the industrial 2V rejuvenator, and intended for smaller batteries. If it can push any current through the cell, it will continue to charge it, otherwise it thinks the cables are either disconnected, or the cell is shorted.

Since I am away from that site for the holidays, to facilitate repairs at home, I will have to wait to try this until next year.

Any suggestions are welcome in the interim.

Quoting:baerndorfer

this is my circuit if someone like to replicate.

What is the difference between the E80/38/20-3C95 and the E80/38/20-N95 cores?

Hi everyone.

The difference lies in the type of material.

One is Ferroxcube 3C95 and the other is TDK N95.

Here are the specifications for each.

I hope this is helpful.

An interesting site here about battery charging, like John Bedini used to do.

He's an electrical engineer from Vancouver, Canada. So he knows a bit more than average, like all of us who share for free he has detractors but he must have willed it and he holds on.

He operates on an open-source platform. Garage Built Free Energy: No Patents

I've been following his videos for a while now, very interesting.

Excellent open-source project(s). Thank you for that video.

Julian Perry, Master of Science, CEO at Kerrow Energetics is referenced in the video.

He has several articles regarding Pulse Induced Energy Gains.

This one is a good tutorial on "flyback pulses":

Hi Inception

Here is his research center with all the information available for free.

An excellent research site on Adams motror.

Fork Lift batteries update:

Battery #1 charged almost fully with the large radiant chargers, first using the 2V cell rejuvenator, then the industrial 12V charger, 6 cells at a time. It needed prolonged rejuvenation.

Battery #2 had a negative voltage cell, which indicated it was destroyed, according to experienced specialists. The rest of the cells did not charge much above 2V.

These batteries were abused by the estate caretaker that exposed them to sub-zero F temperatures, failed to charge them, and let them sit dry for long periods. The individual cell casings where swollen and the electrodes raised, indicating frost heave and expansion.

Due to lack of time, I abandoned further rejuvenation and asked a friend to recycle the lead at his discretion.

Inverters/Solar chargers:

I relocated the inverters to our new location. It took 3 large men to remove them from the wall and load them on a truck. They weighed around 150 kg / 350 lb and now are in the barn until I can find a place to remount them.

The inverters can be repurposed with Lithium batteries, and the solar chargers will be updated to mppt. The original chargers had 70% efficiency compared to mppt devices, which are in the 90s.

Future battery maintenance:

When I return home, I will gather components to replicate a series of Baerndorfer's radiant chargers. A couple weeks ago the Renaissance Charge - Universal Charger developed a short somewhere, and trips its circuit breaker. I have over a dozen vehicle batteries in maintenance mode during the winter season, and the radiant charger helped keep them fresh and rejuvenated for many years, especially the 12V deep-cycle hybrid batteries.

Current:

I am away from the estate repair project to take care of matters at home during the winter storms, but have to return in a few days to finish up.
