went to a chemistry lecture recently to find out what happens and the significant words were "when the anions and cations in a solution combine they can form an inert substance .<br>so no the li fe lion cell once they are below 2.7 volts the damage is not repairable hence the sophisticated battery managements systems .<br>my one actually disconnects the battery from the vehicle as soon as any cell gets to 2.7 volts even on a sudden peak spike of low volts.<br>so you will just have to chuck it away as it could explode<br> as one of mine did when charged (no fire just a bloody mess)<br><br><div><hr id="stopSpelling">From: marshland@marshland.co.nz<br>To: chchrobotics@lists.linuxnut.co.nz<br>Date: Sun, 13 Nov 2011 10:21:36 +1300<br>Subject: [chbot] LI Ion battery 0v<br><br>

<div><font face="Arial" size="2">Hi I purchased a large 3 cell Li-Ion battery pack
off eBay. After one use, one cell is at 0v. The other 2 are 3.7. Can the cell be
