HCH2 - IMA battery reconditioning

Re: HCH2 - IMA battery reconditioning
So, 15 hours? Keep going.
Can you feel slightly warmer air exiting the pack?
I forgot this was an HCH2. Process modified as follows:
1) Grid charge for 19-25 hours
2) High wattage (100W+) discharge to 158V - NOTE THE TIME to discharge to this level.
3) Low wattage (<60W) discharge for the sooner of 5 hours or 106V.
4) Grid charge for 25 hours @ 350mA or 8,800mAh input at < 500mA

Yeah The baterry pack is about 40°C so i can feel that I feel that the sticks that are on the side are warm.
I disconnected the charger because I thought something was wrong
Why does the voltage drop down when connected to the charger?

Re: HCH2 - IMA battery reconditioning
As I wrote before, I disconnected the charger for 2 hours. And I connected it again. The battery charged this time up to 185 volts. because the total charge was about 19. I decided to start discharging the battery.
I connected 2 100W bulbs. And I wonder They do not give too much light.
Should this look like it? These are 2 100W bulbs for 230 V voltage because I live in Europe so the voltage here is 230 volts

Re: HCH2 - IMA battery reconditioning
40°C with cooling means the pack is fully charged.
The voltage drop near the end of charging is due to the temperature increase.
Since you are using 230V bulbs, use only 1.

Re: HCH2 - IMA battery reconditioning
Then I'll recharge the battery to full tomorrow.
Because if I took one bulb now, I could not compare the discharge time to the next one.
And then I will ask if it is important that the Discharge process occurs immediately after the charge?
And can you stop discharging and resume after a few hours?
Will it actually be effective?
I ask because I work 8 hours a day and it will be difficult for me to complete the whole discharge cycle In one period

2) No, but it is helpful if you're comparing discharge times between cycles.
3) Yes, but again, it will influence the timed results.
4) Yes. No difference in effectiveness except for the issue with time comparison.

Re: HCH2 - IMA battery reconditioning
I do not know if I understand correctly. If I connect two 100W bulbs in series. Will they be like 2X 50 W? Or like 2X 25 so 50W in total and how about only one 100W bulb? Will it work with full power? So the battery will discharge faster with only one 100W bulb?

Re: HCH2 - IMA battery reconditioning
2X 100W in series are like 1X 50W by itself.
Bulbs are like resistors. When you put them in series, their resistance adds, so there is less current flow.
You will discharge faster with only 1 100W bulb.
2X 100W bulbs in PARALLEL will behave like 1X 200W bulb.

Re: HCH2 - IMA battery reconditioning
You want it to take longer. Since you're using 230V bulbs, I would estimate it's only pulling about 350mA.
In fact, at that current, you don't need to switch bulbs. once you go below 158V.
