![]() ![]() I wouldn't be surprised if every cell is dead if you left the battery for 2 years and uncharged. You need to check the voltage of every cell and replace any that are dead. Rebuilding a battery requires finding and replacing a few bad cells with new ones. So, if you let your battery sit for two years after running it down to 2.6 volts, it likely self-discharged to under 2 volts and destroyed the cells. If the voltage in a cell discharges to under 2 volts, it will destroy the cell. They appear as zero percent, but actually still have power in them. The batteries have built-in circuits that will cut themselves off at 2.6 volts. However, lithium ions also self-discharge, and over a long enough time will completely discharge themselves.

You let the battery sit for 2 years unused? Two things happen to lithium batteries as they sit on a shelf. That bug, as you know never really goes away. After making it over 5 years without killing myself I decided it was time to stop tempting fate.
