If anybody has a Tektronix TDS30xx of TDS30xxB oscilloscope you should read on...
This afternoon I had a phone call asking me to urgently contact all the customers we had ever sold a TDS3BAT or TDS3BATB battery to, it seems that there have been a few Tek scopes catching fire because of the Lithium-Ion battery. Tektronix are asking anyone that has one of the batteries in their scope to remove it immediately and not use it again until they can figure out what corrective action they need to take.
