      Lithium ion cell voltage not going up after 3.8V
      by tmhobadcap
      I got a chromebook with battery problem. It was charging when plugged in. But the indicator just showed that the battery was below 10% no matter how long it was plugged in. I took the battery pack out. There are two cells in series. Each cell had a voltage of about 3.7V. I charged one of them with a lithium cell charger. I can see current going into the cell at about 500mA. After several hours, the voltage was just about 3.8V. I charged it again manually by connecting 4.2V to it from a power supply and set the maximum current to 500mA. I can see about 100mA going into the cell. But the voltage...

      Elitebook 820 G3 engineering example: CMOS settings lost despite new cell
      by i440bx
      Hey there,

      I got a HP Elitebook 820 G3 Engineering Sample Laptop and I want to use it. Besides the difficult things at the ES-BIOS I have a big problem by saving the main BIOS settings.

      The laptop does not have a big battery because it was dead, but I already plugged in a new CMOS battery.

      It takes about 5min without power and the BIOS settings are lost. Unfortunatly I dont understand why the BIOS settings are only saved with power connected and this is the reason why I registered here.

      As written above, I plugged in a new CMOS cell and checked...

      Sell or Shim Solar panels?
      by eccerr0r
      Well, due to my grid tie inverter not accepting high voltages, and the fact that the lions in my solar panels are 36V (72-cell) I think I need to stick with 72-cell.

      However I have a few smaller panels that are 36, 32, and two 30-cell. The 36 and 32 together run at 75% efficiency (and subtract more with additional inefficiencies) when running in parallel with the 72-cell panels. The kicker is that the two 30s... generate 0% power when connected in parallel(!)

      So now what to do with these small panels?

      I could sell them...

      Or I could shim them....
