Hi guys,
I ordered the higher capacity battery CS-AV605XL on ebay last Tuesday and it arrived today :D
The battery is described as 5200mA Extend Battery to Archos AV605 AV 605 Wifi 80GB.
Now, this battery is twice the thickness of the standard battery
and comes with a back cover to fit only the 4GB and 30GB models 8).
So,unless the 80GB or any of the other higher capacity 605s
already has the free space inside them to accommodate the battery
then it will not fit them.

A couple of things to note if you decide to upgrade to the 5200mAh battery:
It adds an extra 3mm to the thickness of the device therefore
the tabs on the back of the docks will need to be cut off/filed down
so that they will fit onto the 605.Also the 605 wont sit in the DVR
station with the saddle fitted - again cut and file or remove it
completely.The good news is that it still fits into its noreve case
albeit a bit more snugly. :)

The battery took just under 3 hours to fully charge in the DVR station.I haven't had time test how much more playback time it adds - maybe tomorrow.
Here are some pictures:

High capacity battery fitted to my 605

Very nice. Please post the video play back you get off it please. This could be very interesting. Thanks a bunch!

Would you recommend someone get this high capacity battery if they are not sure of how to replace the original? Or can I take it somewhere where someone would be able to swap the original in place of this higher capacity model battery?

What's the built-in batteries charge? 2800mAh?

Is that tape on the end of the leads or some sort of connector? Did you just snip the old leads off and splice the new ones on or did you actually resolder?

No,I wouldn't recommend you replace it yourself if you're inexperienced at soldering.You'll also need a steady hand and good eyesight because it's very easy to create a short on the PCB.
Also you need to be aware of the danger of thermal runaway if you short the battery leads accidentally.
Check this thread especially the post by PGR:

If you take it to an electronics repair shop they should be able to replace it for you without much trouble.

The mAh capacity isn't written on the original battery.But, standard replacement batteries are rated at 2600mAh.

the originals i think are actually 2600ma, so this battery effectly doubles the life expectancy of the player. ive just openend mine up this after noon becasue the speaker was vibrating (put some foam behind it) and i was suprised how easy the battery was to remove and how accessable it is on the 4gb player. there is no reason that archos didnt originally make these removalable and im seriously thinking of making something that would allow gen 4 batterys to slot in place for quick on the fly changes.
nice find im a bit mythed to why the seller has 30gb batterys 2600ma and 80gb batterys 5200ma, yet you have put the 80gb battery on the 4gb, i wondering if this will work the other way round.
hurry up and get a test up, im dieing to see how long that baby last now, im guessing 9hrs 30min on low lcd setting and 75% volume. would be nice to break that 10hr mark on internal battery though.
for mp3 im guessing 27hrs.

Yes it's tape not connectors.
I soldered the leads directly onto the PCB.This has the advantage that if I do need to RMA it I can easily replace the original battery and they wouldn't know I had been tinkering.

So do any replacement batteries fit in the 160GB?

Hi guys
Here's the result of the battery test I did today.
Start time -- 11:30 hrs
Shutdown time -- 20:10 hrs
Total continuous run time 8 hrs:40 mins
Display settings: LCD backlight 1,brightness 16,contrast 32 and gamma 2.
Volume 70% (24 clicks from zero) to earphones.

Films used for test:Gladiator,The Bourne Identity and The Matrix.
Codec Xvid, Bitrate 1200kbps, Resolution 640X360, MP3 audio @ 128kbps.

Note:this test was with the very first full charge.
Once the battery has gone through a few more charge/discharge cycles
it should give me a little more playback time. :D

nice,that very impressive,and it looks very clean on that back(just that fact that it sticks out a little,but who cares?)i can get only bout 2 1/2 movies (1h45m running play)

Outstanding soapy! And that was off the first charge. I bet you will get that 10 hour mark once the battery has been nicely cycled 3 or 4 times.

Is it right that you got the 80gig battery but have it in the 4gig 605? If it adds 3mm to the thickness and does not have the ability to stick out the back of the larger units like it does for the 4gig 605 my fear would be that it would press down on the HD and perhaps damage it when spinning. It really looks like it was made for the smaller 605's and not the 80 or 160gigers. The back of my 80 is much different than the 4gig model you have there.

Great job with this!

This is truely awesome!

Hi Kodiak,
Yes it is the 80Gb battery in my 4Gb model.Well, the suppliers on ebay described it as a replacement for the 80Gb battery but it seems to me that they've wrongly labelled it.As soon as I saw the picture of the included back cover I could see it looked nothing like the covers on the higher capacity models and more like the covers on the 4Gb and 30Gb.
So I sent them off an email to query if it would be compatible with my 4Gb model.But they never really gave me a conclusive answer.They just said if it's the same or near the same capacity it should be compatible with the battery for the 20Gb Archos :? I took the plunge and ordered it anyway and as you can see its paid off.
Now,my guess is that since the 4Gb and 30Gb models need a deeper back cover to accommodate the extra thickness of this battery,the higher capacity 605 models are going to need one also.I just cannot see them having that much free space inside.

Yup,hitting the 10hr mark would be sweet,but going by the experience I had with the standard battery,I do think that once this battery goes through a few more charge cycles I should get another hour playback time out of it.So roy's guess of 9hrs 30min is going to be pretty accurate I think.Woohoo!

Heres what I was thinking. I have read about a lot people getting in the 3:00 to 3:30 hour range right out of the gate with the 605. After cycling they improved to the 4:30 to 4:50 range. A 30% gain would take a 3:30 battery to 4:33.

If you got 8:20 (500 minutes) out of the first charge and you only get a 20% gain after cycling you would get a 100 minute increase. 500 + 100 = 600 minutes. 600 minutes = 10 hours! This is if you only get a 20% gain. I think you will be surprised, and overjoyed :lol: , with the battery upgrade you took the chance on.

This is enough to make me consider getting a 30giger just to get to add this battery. It is designed for the smaller models and not the 80 or 160. My plant closed down and I had to find a new job so I don't think I will be traveling like I used to. With that extra battery I would need no other attachments for any travel I would do. Thanks again for taking a chance on that battery and letting us all know the results.

Only problem with that theory is charge time... it would take about 15-20 years to charge via USB :lol:

:lol: On second thought the Battery Dock is a wonderful accessory to have. :lol:

thanks for trying out this new battery.
looks very promising.

could you possibly take a photo of how and where you had to connect it to the archos. i'm sure lots of people on this forum will benefit from this thread!

:D

I'm a little confused here about some of the things that have been said regarding charging the battery. I've read that with the lithium-ion batteries that you shouldn't let it drain out as it will shorten the life of the battery, they like frequent charges. But in this thread I see people talking about "cycling" the battery, which I'm assuming to mean that you let the battery drain out and then charge it back up and do this 3-4 times and then can get longer usage out of the battery charge. Is this true? I've had mine for a bout a month, can/should I still cycle it? Thanks for any info you have.
