Lead Acid Battery, Wet,gel,agm

Hi Guys,

I have now gotten a set of larger sulfated batteries with a residual voltage of 2.5 volts per battery.

I first tried it with the capacitive battery charger and made the battery conductive with a slightly higher voltage. Then charged with a 24V transformer and rectifier. First there were immediately 25 volts where both batteries were connected in series, then I charged them it took a lot of power on which I have lowered with the Variac on a lower charging voltage. Unfortunately, the voltage continues to drop, I now have only 12 volts although both batteries had previously 25 volts. The batteries take the power. I always thought sulfated batteries have an extremely high internal resistance and do not accept any charge.

Or are now multiple cells just shorted and therefore guide so well.

I can get batteries here that are actually very good but can not be replenished with water. A Hoppecke SB60.

I am looking for the ideal energy storage for our my attempts.

regards

Sven

It takes several weeks to renew them .one hi amp diode...scrap yard car
alternator... a cord off of a old fan ...ect.. A light blub with holder
..put inseries with battery . plug in to wall . light comes on when your
getting some were. Good hunting

Hay I forgot about the capacitor to cough off the current ..😬

I think I explained how desulfation works .....

Use hi voltage vectored from resonant LC by means of a diode bridge ,Say 500VDC  voltage will go UP and start to go down , as it gets to  10-11 volts STABLE then you can charge in normal mode , USE HYDROMETER to test battery specific gravity charge  dilute if too much at total charge add acid if its too low ... equalize and measure again ,  A microwave transformer can be used to deliver 1000 desuphating volts to it !  just limit the primary current with a 100 W lightbulb in series to primary  or use RV 3rd phase juice  



Fixed !  (H)

Hello,

with my battery is the voltage
broken together. 4.5 volts with a 12 volt battery. The internal resistance is surprisingly extremely low. Have now missed a few nasty surges and it is back to 10.8 volts.
I do not know if all the effort is worth it, maybe the lead oxide settles on the floor and closes the cells short and therefore the internal resistance is so low?!?
Although this would be very strange as the internal resistance of the battery increases due to sulfation. Well.
thanks first of all

Greeting

Sven

Hello Hector,

not an issue, I have the battery in the resonant circuit driven by a Variac. The voltage on the battery dropped slowly from 90 volts to 12 volts. The internal resistance of the battery gets super lowered. Unfortunately, the voltage has dropped further down to 4.5 volts, but the internal resistance is extremely low. I am currently trying to recharge the battery via a 230V / 24V transformer and rectifier. Of course, the stepdown transformer is controlled to the correct output voltage via a Variac.
The siphon does not work here, unfortunately, almost all batteries are tightly closed, in this case, the lid is even welded plastic.

What are the optimal batteries, could you also take Li-ion?
What about gel, AGM batteries. Unfortunately, they are no longer fillable with acid or distilled water.

Resonance can be used in any battery , but has to be specifically tailored for it ..  so you can automatize the cycling processes and optimize them for extra battery life ... I did  some tests with raw 3.4 to 3.8 lithium polymers and the speed of charge  with NO heating amperage regulated is incredible they charge as fast as a wet fart coming out of Kim Kardasians big ass ! i was afraid it was going to explode ( the battery ) not kardasian ass! 



(H)   lol !

Super Kim is back. laughing.

I think I get a battery back again just 13.5 volts at 2.5 ampere charging current conventional, I have a thick Elko smoothly installed. Let's see how it develops.

I still have 2 Panasonic AGM batteries worried the 80% have, I can not get on otherwise.

The 18650 Li-ion cells can get quite cheap and install them cleanly in battery compartments. But apparently you have to take sufficient protective measures if you want to play with them.

Sven
