    well i've called asus and told them about my problem and they quickly issued me an rma for the battery. i'll probably ship it out within a week and we'll see within a couple weeks hopefully whether everything works out.

    On this system that I'm on, for four years, the battery has decayed, and thus 75% of the battery cells have expired, and I'm only running on half of the last battery cell. At best, I can get up to an amazing 25 minutes of run time before I have to run and find a nearby wall outlet. :) Then again, this system isn't meant to be mobile, but a desktop replacement which fits nicely on to a small coffee table. :)

    Where can you find the wear level of your battery accurately? I'm using some program called MHC ( I think ) that's telling me I have 30% wear level on my R1. I've had it since the first week it came out - since October sometime, but I just thought the wear level was a bit excessive

    I think you mean, NHC and that's what I'm using also. I dont know of any other programs, though it would be nice if there were so I could double check the NHC wear value.

    edit: I downloaded a program called batterymon by passmark and it seems the battery wear level reported by nhc is accurate when compared to the levels reported by batterymon.

    edit2: does anyone know if its ok to run the tablet without the battery?

    It's not recommended to run the computer without the battery It can cause damage to it. The wear out of the battery varies from manufacturer. It seems line these Asus 's batteries should last good. Also, you can find the battery recalibration in the bios menu and run it once or twice a year, or it your battery is really bad.

    Where have you heard this?
    I for one would appreciate reading where you have found this information.

    As to the battery that ASUS supply ~ ASUS are the only manufacturer I know of who give a full 12 months warranty on their batteries.
    Seeing as batteries are classed as consumables, this is an excellent warranty and full marks to ASUS in doing so.

    I read this in this forum:
    http://www.techzonept.com/showthread.php?t=96777&page=2
    and this is what a user says, in Portuguese, from what Asus technical assistant told him:
    "Post Original de spor
    Do mail que enviei disseram-me para ligar para eles...

    O assitente técnico da Asus que me atendeu disse-me que nunca se deve tirar a bateria, pois cria um down não sei quê (era um termo técnico daqueles de ficar de boca aberta). Ao fim de +- 3 meses a tirar a bateria vai ser preciso recalibrar a mesma. Já que os técnicos da LG também disseram o mesmo tomei a decisão de nunca mais tirar a bateria."

    Let me just say that what said is just part of the conclusion of many users said with their interactions with their laptop manufacturers TA

    This was written by an Assistant Technician at ASUS.
    As much as I would love to believe him (and the comments of the other posters) I go with experience and usage as my verdict.

    We each have a valid opinion job, I respect yours but I will go with my own personal experiences.

    I've used Laptops for more years than I'd care to think of and throughout, I've always taken the battery out if I intend to use the machine at a static point for periods of longevity.
    Batteries soon get hot in use and when coupled with a charge only increases the problem.

    By taking the battery out I've managed to keep them in good working order, all at no risk to the laptops they came from.

    Don't get me wrong. Of course we all have valid opinion because from what I perceived from the long topic on the referred forum, diferent manufacturers give diferent advice. If that has to do with the diferent batteries or hardware schematics, or diferent TA opinions I don't know. But as here, in that forum, there are diferent experiences, and in fact there is people that as you, take the battery out when they can. The quoted user only says about his expereince, that his laptop got damaged and the people of Asus said that most likely could be caused by not having the battery at the time. That is said in another place in the same topic. They also led him to observe that most of the laptops have on their batteries support a stand to stay balanced, and that is done because the battery should not be removed. If they say taht so we can wear out the batteries and they have more sales I don't know. I just know that on the topic there are people with opposite experiences, from diferent laptops, not even diferent manufacturers. There is a person who says that the main things we must be carefull is: to avoid recharge the battery before it raches 40% although these Lithium Ion batteries don't have memory so they don't get "viciated"(I don't know the english term); once recharging let it recharge completely (very important); be carefull with heat which is the worst thing for these Lithium batteries.
    I hope I shed some light on this issue which is a great concern for me, because my Toshiba Qosmio battery lasted only 8 months, although they give me a 24 mo warranty on it. I am not an expert, just a concern user who is trying to get exact information about the issue.

    And your opinions are greatly received job.:)

    I hear what you say about certain batteries have the 'moulded stand' built in to the foot of them.
    This was initially a concern for me but in the end I got round the problem by designing a 'false plate' which fits precisely over the gap left by the removed battery.

    Each to their own job.... each to their own.:)
