What kind of batteries are in my V2/FMR? +A1. They are 2200 mAh LiIon 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 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 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. + +Q4. How long should fully charged batteries run for? +A4. 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. + +Q5. How long does it take to fully charge the battery? +A5. About 50% charge is applied in the first hour. The rest takes up to 3 + more hours. + +Q6. I want/need a replacement charger. What kind should I get? +A6. A charger/adapter that outputs 6VDC at 700mAh and has a power plug with a + 3.4mm O.D. x 1.3mm I.D., with positive center will have the same specs as + the original. + +Q7. I've heard about options like deep discharge, but can't find them in the + menu. Where are they? +A7. These options are for the recorder (V1) only. Charging for the recorders is + done by software, but charging of the V2/FMR is controlled completely by + hardware. + +Q8. Can the FMR/V2 charge its batteries through the USB port? +A8. Yes, though slowly since USB is limited to 500 mA. Charging is reduced or + eliminated when the FMR/V2 is connected through a passive hub. If a PCMCIA + USB 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 card. + +Q9. Can I run my V2/FMR constantly with the power adapter plugged in without + any negative effects? +A9. Yes, as long as you aren't draining the battery faster than you're + charging it (like reading/writing a lot in USB mode). + +Q10. Is it ok if I recharge the battery when I've only drained it part of the + way? Will that reduce the life of the battery? +A10. You can recharge at any time. Li-Ion batteries have virtually no + memory effect. diff --git a/www/docs/Makefile b/www/docs/Makefile index e996c9da39..dd66652a8e 100644 --- a/www/docs/Makefile +++ b/www/docs/Makefile @@ -31,6 +31,12 @@ battery-faq.raw: $(DOCS)/BATTERY-FAQ $(FAQ2HTML) battery-faq.html: battery-faq.t battery-faq.raw $(FAQ2HTML) $(ACTION) $< +battery-faq-liion.raw: $(DOCS)/BATTERY-FAQ-LIION $(FAQ2HTML) + $(FAQ2HTML) < $< > $@ + +battery-faq-liion.html: battery-faq-liion.t battery-faq-liion.raw $(FAQ2HTML) + $(ACTION) $< + contributing.raw: $(DOCS)/CONTRIBUTING $(TXT2HTML) $(TXT2HTML) < $< > $@ diff --git a/www/docs/index.t b/www/docs/index.t index 4d078ce715..d8064f7161 100644 --- a/www/docs/index.t +++ b/www/docs/index.t @@ -6,6 +6,7 @@
