Hello, i have a civic hybrid 2008, i haved grid charged for about 18 hours, starting voltage was 177, i stopped at about 190 volts. After that i left home for a trip and iti worked excelent, assit, regen, autostop, 8 bars, 7 bars until 4 bars. I was delighted. In the morning i started the car and the simptoms before grid charghing came back ( 8 bars strainght to 2 bars regen and back to 8 after a short acceleration). My guess i think i don't let the car charge enough time?
( a year ago i recondioned the battery stick by stick and iti worked for about 6 month, two of the sticks were a little problematic but they worked)
Your guess is wrong. You've likely already discovered the issue - "two of the sticks were a little problematic but they worked"
These thing fail by excessive self-discharge. They just stop holding a charge, and there's nothing that can be done to fix it. That's where you are. You limped along for a year with partial functionality, and now the best you're going to get is a day of decent performance after a grid charge. After the first overnight sit, the bad cells have bled off almost all their charge, and you're back to recalibration time.
i will try to charge for 29 hours ( 5.5Ah * 1.6 / 0.3 Ah = 29.3 H) and test the result, if it is the same i will try to change the problematic stick and see the result
After a few weeks after trying with the charger my battery still holding charge for only a day, I built myself a discharger following this intructions ( https://hybridautomotive.com/pages/sd ).
I charged the battery 12 hours, after i let it drain for about 6 hours to 110 volts and then charged back 12 hours to about 186 volt.
I`m happy to say after 3 weeks my car and battery works great, no recall, no CEl or IMA lights, assist far longer.
