Well that sucks.

Well, I know I'm coming to this topic a bit late, but I've got a stock n810 battery I grabbed a while back to have on hand in case I needed it. Turns out, it's stayed in the package and I have yet to use it. Ever. Period. My regular batteries are holding out so well, there's no need to have it anymore. The darned units will wear out before the battery does. o_0;;

So it's for sale. $40 + shipping. US/Can only. And yes, it's still in the original packaging and sealed.

Do you know that lithium batteries degrade over time even if you don't use them?

I sent off for the expensive Mugen replacement for the N810 recently. Unfortunately, I must have clicked the wrong square, because instead of the United States, my order says it should be shipped to Agoura Hills, CA 91301 Uganda. So that might delay shipment

Note to 800 users: the Mugen battery for that device is apparently out of stock.

lol. Sounds like you lucked out. Guess you need to cancel the order before they do ship it then.

And on a side note, you could always just buy the spare I have.

Sondjata,

When I ordered my N810 battery it was out of stock too. But when I was going to cancel the order, the suggested me to wait for a couple of days, when they were expecting new batteries to arrive. It was like they said and after ten days I had my battery. And it went from Hong Kong to Argentina. I cannot complain.

So my cheap battery saved my vacation (can't live without my tablet).

In the car I was using my GPS to drive to my destination. Unknown to me the car USB charger didn't supply quite enough power to charge the (stock) battery and run the GPS/screen so my battery slowly discharged. Just as I turned on the street of my destination, my tablet turned off and rebooted. It stayed in a reboot loop so I powered it off and waited until I got inside. Inside I tried a (non Nokia) wall charger but still was stuck in a reboot cycle. I gave up and decided I had to reflash when I got home. A few days later I remembered that I had thrown in my backpack the cheap batteries I got from Deal Extreme. I popped one in and the tablet still went through a reboot cycle but then managed to boot up. I immediately took a backup. During the following week, I had one random reboot but other than that the tablet was my friend again. I deleted and recreated the swap partition after this reboot.

So when I got home I started trying to diagnose. I connected to a host computer via USB and scanned the internal flash where the swap was located and didn't find any problems. I decided I had better reflash since I thought I had problems on the internal flash file system for some reason. I did see a jffs2 warning in dmesg after the last reboot. But I wanted to put the stock battery back in.

When I put back the stock battery I found that it was completely dead but since I had my Nokia wall charger, it booted fine.

So my working theory is that I discharged the battery completely, none of my chargers that I tried would charge and supply enough current to boot (and charging requires booting), and the reboot loops corrupted the jffs2/swap.

The latest boot did not produce any jffs2 messages so I think I can avoid reflashing.

But the $3.25 battery was a nice safety cushion that allowed me to have my tablet during my vacation. Of course having the Nokia charger would have worked as well. I actually did have a full current USB charger that would have worked as well had I known what was happening. Oh well, hindsight and all.

Ya know Frank, I've been thinking about this. The NIT shouldn't be cycling like it did when your battery was uber drained like it was. Once the NIT is on mains power, it shouldn't matter what state the battery is in. It should still, in theory, run. Heck, once mains power is plugged in, it should still run even without a battery. So it's less likely that your battery was too far gone to power it, but rather that it got corrupted or damaged somehow and was causing the unit to kernel panic and reboot.

I would agree with you if I was using the Nokia charger but I wasn't. The Nokia charger is rated for more current (890mA) while I think the chargers I tried were probably 500mA or less.
