Jetbook battery life
I was just curious what other Jetbook users were getting for battery time before recharging. Mine averages around two 300 page books.
How long does yours last? |

The battery is rated 20-24 hours. A charge last me about a week.

I charge mine in about 10-12 days. Am I correct in remembering that it is good to discharge lithium batteries all the way about once a month, or perhaps once every 10 charges on the long-life batteries?

Quote:
The practice of periodically deep discharging rechargable batteries comes from the days of NiCad batteries, where it sometimes helped with what was called "memory effect". The newer NiMH batteries are not prone to this "memory effect" and don't require periodic deep discharge. Although not needed, I understand that this practice will not destroy a NiMH, as it will a lithium. Lithium batteries are usually rated about 1000 recharge cycles. From what I read, a partial recharge only counts partially toward one of these recharge cycles. From my own experience with cell phones, which I charge every night, I typically get 3+ years before the capacity of the battery drops significantly. The battery is not dead, but it no longer has the capacity of a new battery. If you take the 1000 hour figure and divide by 365 days, you get 2.74 years. From this, it seems that the 1000 hour figure is probably conservative. |

And now back to our regularly scheduled program
As to how many hours I get from my jetBook, I haven't timed it, but it seems that the 20+ hour figure is about right. I've read 4-5 lengthy short stories and only charged it once since the initial charge after unboxing it. Adding to what I said in the previous post, I would suggest using the jetBook until the low battery warning appears and then recharging. This should give the longest life from the battery. If you don't want to be interrupted in your reading, then any time after the battery meter drops to one bar and you are done reading should be fine. Last edited by jgray; 06-15-2009 at 02:15 AM. |

Oops - hope I haven't been ruining my batteries! I'll have to be more careful.
Thanks for the info. |

The only battery information I saw before I bought was the number of page turns on the jetbook website, which I thought was useless as it was LCD, so its good to know that mine is doing fine cause I have the worst luck with rechargeable batteries.
