Really? Do you have any evidence for that that claim?

This is just more of the usual alarmist nonsense about lithium ion 
batteries. This should be the kind of forum where we discuss the design 
of lithium ion battery chargers and lithium ion battery condition 
monitors - which could, in principle be designed to discharge the 
battery if the internal temperature of the battery rose high  enough to 
suggest a risk of runaway self-discharge.

Cursitor Doom and John Larkin are much too devoted to their alarmist 
fantasies to want to think  about that (always assuming that  they could 
if they wanted to).
