Subject: FMR/V2 battery faq draft
here's what i have so far. please point out any questions (or
spelling/grammar errors) i've
Q1. What kind of batteries are in my V2/FMR?
A1. They are 2200 mAh LiIon rechargable *AS rechargeable batteries.
Specifically, it is two 1100 mAh LiIon
cells in parallel, physically taped together.
Q2. Can I change the batteries?
A2. Yes, if you can find replacments *AS replacements. Archos does not sell
them. One site that does is:
http://www.pdainternalbattery.com/archospdabattery.html. Alternately, there
are companies who make
replacement battery assemblies that might be able to help.
Q3. Ok, I got a replacment *AS replacement, now how do I put it in?
A3. Remove the two small screws on the top of your V2/FMR, and pry the lid
off. Now turn it upside
down and shake it a little. It should just slide out. Take note of the
position it's in, and put
the replacement in the same way. Replace the cover. *AS, question, can
putting the batteries in the wrong way destroy the unit?
Q4. How long should fully charged batteries run for?
A5.*AS A4, not A5 It depends on how you use it. If you're doing hard drive
intensive activities like formatting
or transfering large amounts of data, probably only a few hours. If you're
only using it as an mp3
player it will depend on the bitrate of the mp3s. Playing 128kbit mp3s, it
should last around 8
hours. Playing lower quality recordings (32-64kbit) like audio books it
could be more like 12 or
14. Playing very high quality files (256kbit+) it could be more like 4 or 6
hours. Also, doing the
8MB RAM mod will significantly increase battery life.
Q6. How long does it take to fully charge the battery?
A6. About 50% charge is applied in the first hour. The rest takes up to 3
Q7. I want/need a replacement charger. What kind should I get?
A7. Any charger thats *as that's 6V, 700mAh, and positive center will work.
Q8. I've heard about options like deep discharge, but can't find them in the
menu. Where are they?
A8. These options are for the recorder and player only. Charging for the
recorders is done by
software, but charging of the V2/FMR is controlled completely by hardware.
Q9. Can the FMR/V2 charge its batteries through the USB port?
A9. Yes, though slowly since USB is limited to 500 mA. Charging is reduced
eliminated when the FMR/V2 is connected through a passive hub. If a PCMCIA
adapter is being used in a laptop or similar device, it is very important to
connect the external power supply if one is provided. The PCMCIA port cannot
supply sufficient power by itself. The Belkin USB 2.0 adapter, for example,
comes with a "wall wart" power supply that can be plugged into the PCMCIA
several more questions. First, will Archos replace the battery?
Secondly, since the 8 MB mod will extend life, is there anyone who will do
the mod for people? Thirdly, what happens if the battery dies and the unit
is playing? Does it have an orderly shut down mechanism or something?
