^^^^ There you go, Like I said I think your battery is fine just not fully charged... Keep charging them for at least 6 more hours.. Let it sit for at least 3 hours with no load on it if you can then check the cells again... I bet they will be the same...

Let it sit for at least 3 hours with no load on it if you can then check the cells again... I bet they will be the same... The low cell is now up to 1.265, I am still charging, has been about 5 hrs so far today. Was about 8 hrs yesterday. I have learned the best and most accurate way to check the charge of your battery is via hydrometer. It appears to me that my batteries were not getting sufficient charge via the solar. I am wondering if this is a shortfall of the charge controller ( when it says it's at 100 % it's not), or do I not have enough solar panel, should I add another panel? I will also start checking specific gravity once a week and charge with generator if reqd. |

LOL The short fall is you are still wondering about the CC saying the battery is at 100%... Forget about it it means NOTHING... It even says so in the manual...
Go for 8 hours today and see what they are in the morning...
Ok I looked back at what you have. Yes I would add one more panel if it was me.. That's all you can add with the 40aCC you have now.. I would also add two more batteries for a total of 4 when your batteries you have now die... I wouldn't add 2 more now as it's not good for the new ones...

I have a 240 watt panel, and the CC is Renogy 40 MPPT. |

Yes sir you are getting close, It took mine 5 days of full sun to charge mine fully with no load on them as I don't have anyway of charging them with a charger... |
