We’re not sure that how many months they claim to run matters much. A supposed run-time of 4 to 5 months rather than a month or two might, we suppose, be marginally more convenient. But it could also allow more opportunity to, say, misplace that seldom-used battery charger.

Our bottom line with battery life and e-book readers: Pay attention to whether the battery times (based on manufacturers’ claims) that we include in our Ratings are in hours (like the models that have backlit LCD screens, such as the Nook Color) or in days or weeks (like the models with E Ink screens). After that, worrying about relative differences in battery life may consume more energy than it’s worth.

Smart. Very smart.
