How quick is pretty quick? I am hemming and hawing on buying one of the 3600mah battery, as I will need the extra power for my backpacking trip through Wales. I was about to buy one when I saw your post with the problem on the batteries, so I am hesitating again. Just need to know how long I can wait before I make a decision and still get them before I leave.

Thanks!

Scott

Ordered 10pm on 16th

Email 5am on 18th to say shipped by ETEN

Postman delivered (recorded delivery) 22nd

Thanks for the quick reply!

Have returned both the extended and slim Mugen batteries to Eten.

The extended one I did get to charge, but in use it was unreliable. The slim battery I never managed to charge.

Pretty sure its just the battery contacts, the standard Nokia one, the gold contacts on the battery look like they come closer to the edge of the battery and look more substantial.

This is very discouraging news...

But thanks!

Hmmm... seems like you could fix that with a little solder. Then again, if you tried and it didn't work, you probably would have a hard time sending it back.

Eten have been good about it in email contact, have emailed them the photos too in the hopes that they can get the product improved.

Will keep the thread updated once the batteries arrive back with Eten and see what they say.

Sure, wedging some paper against the battery got the extended one working, and you could modify the contacts, but I feared I could damage my N810. So better to give feedback to the supplier and hope the product gets improved.

FWIW I quite liked the extra "bump" with the extended battery cover, made it easier to hold and use the keyboard.

I'm sure the bump will mess with my GPS mount though... when I wind up ordering one I guess that's the time to make something myself...

I'd dearly love a battery with 20% more life than the standard battery, and this 1800mAh extended battery sounds like it would do just that. However, I've also seen several reports on this thread of it either not working or delivering no more power. Has anyone used it and managed to get more life out of it than from the standard battery?

Yes, I've tried it and no, you don't get anymore battery outside of the standard 7 hours use / 10 days standby. While it doesn't provide any more juice, it doesn't perform any worse than the standard Nokia battery and for the price, it isn't bad. I've been using it now for a few months and I don't have any issues to speak of, so even though I've read some have been given a defective battery, mine is working as well as the day I got it.
