Jetbook Lite battery tests

[ricardo123]

My mum's JBL just arrived from Ebay today. It's excellent. Does the job it's required. When the Duracell Ultras on my old Handspring Visor PDA finally die, I will probably buy another JBL for myself.

Which leads me to the question: has anyone ever scientifically tested real-world battery life on the JBL? How many hours would 4 aa Duracell Ultra's last? Or 2000mn / 2700 mn Duracell rechargeables? I would really be looking for about 40 hours from the ultras.

Thanks

I ran some tests of the standard NiMH rechargables a while back, in this thread:

Not exactually "scientific" but they were specific to use in the JBL.

You should be able to expect between 25 and 30 hours of actual reading time per charge
of a set of the standard Made in Japan 2300mAh NiMH rechargables.

I would also suggest specifically looking for the "low self-discharge" or "pre-charged" variant of NiMH rechargeables, if you're going that route. The capacity rating may be a bit lower, but I believe they are much better suited to the usage pattern of an ebook reader.

Hmm... Amazing...You might want to read the thread I provided the link to.

The Eneloops are very good batteries, Made in Japan.

It all really does hang on what your usage pattern is, if you will be charging
a set of batteries and then not using them for a month, the LSD feature may
come into play. If you expect to only use your ereader a few hours a month,
then the LSD batteries would be a very good idea.
