Q7: What kind of run-time can I expect on a set of fully-charged batteries
when running Rockbox?
A7: For the stock 1500 mAh cells, from 6 hours to 8 hours, depending on
which charger was used (see Q3). It depends a lot on the condition of the
which charger was used (see Q3) and the bitrate you use (higher bitrate
means more harddisk runtime). It depends a lot on the condition of the
batteries. With 2000 mAh batteries, you should reach about 10 hours or more.
We are looking into implementing more battery-saving techniques in rockbox
to make it rock longer.
If you have a modified AJB with 8 MB, you can reach playing times of up to
16 hours with 2100 mAh batteries.
Q8: Can I use different batteries in my Archos? How much playtime would
I gain by using 1800 mAh batteries instead of the 1500 mAh ones?
@ -245,3 +248,14 @@ A16: Nothing's wrong. The battery level is calculated out of the voltage.
battery voltage, it is usual that the battery level is going a little bit
up and down sometimes. This cannot be avoided although we tried to make the
battery level display as little confusing as we could.
Q17: My batteries are at 92%, the charger is connected to my recorder, deep
discharge is off. But charging doesn't start. What's wrong?
A17: Charging starts if the battery level is below 85%. This is because
charging batteries that *are* already more or less full is not good for
the batteries and the end of the charging cycle can't be detected safely.
So it's better to start at a level at least as low as 85%.
If you want to have full batteries in the morning, leave the charger
connected over night. Charging will then start some hours later. The
second possibility: Use the Archos charging algorithm. At least,
your batteries will be full one more time. ;-)
