    The battery that's giving me the 3030 code needs one cell. I got two good cars that need batteries and would like to use this one to fix one of them.

    Are you sure it's a cell and not a broken sensing wire p3030 is usually a sensing wire snapped or corroded bus bars. If I was you I'd bite the bullet and upgrade the whole battery to Gen 2 and up cells

    Yeah, I thought it was wiring as well. Took it apart, checked all the voltages and a few were low, but not realizing that they don't have to be that low to cause a problem, assumed they'd just charge back up. Then I replaced the buss bar harness with sensor wires, and cleaned up the buss bars on the opposite side, and inspected all the other wires, then put it back together and still got the 3030. Drove it a while to see if it just needed to charge up, and it never went away. Then, I put my new Gen2 battery in that car, and the 3030 went away, so I know the problem is in this battery and not the car.

    So, I took it back apart, and found that all the cells did charge up except one. So, I need to replace that one anyway, and hopefully, the 3030 is the ECU just thinking that bad cell is a bad wire. Since all the other cells seem fine, IMHO, it's worth buying one cell to fix this one and using it as long as it lasts, then upgrade to Gen2 cells.

    I should probably pull the batteries out of my two parts cars to see if either of those has a good cell, but if I can buy one cell, I'd rather not go through that hassle. Getting tired of getting these batteries in and out of cars by myself. lol
