To take issue with this lithium batteries in a best case scenario lose 10-20% of the peak capacity every single year from the factory onwards while this isn't a terrible time frame it's magnified by most ereaders having a low capacity battery to start with.
I'm thinking if you treat your ereader perfectly and do everything right you will very lucky if it can even get the initial power draw for it to turn itself on in 3 or possibly 4 years.
