Charging a BL-5J (N900) battery in the N810

There are several reasons why you would like to charge your N900 battery in a N810. Maybe you have a spare battery that you want to charge while using the other battery in your N900, or maybe your N900 refuses to charge the battery by itself. Please note that even though it works for me, the standard disclaimer applies - it's all your fault if this destroys your devices and/or batteries :)

Now, let's have a look at the pinouts and connectors of both batteries:

So, the connectors seem to have the same size, even though the batteries do not. Trying to put the N900 battery into the N810 is not straightforward, as there is a white piece of plastic that prevents the battery from getting close to the connectors. The solution is to simply use the N810 stylus as a lever to push the battery towards the connectors:

After the stylus and battery are fixed, simply connect the N810 to the power adapter, and it should start charging. Thanks to Quim for this helpful hint :)

Aren't there standalone chargers for batteries from Nokia?

Ha ha! You're insane, Thomas. :)

Sardaukar: Of course there are. But this might be helpful for people who do already have a N810 and don't want to (or can't) buy a standalone charger.

Tim: The idea wasn't mine - Quim told me that it is possible. Also, my N900 refuses to charge the battery, so that's something that I actually *need* to do right now ;)

Brilliant!
My N900 won't boot or charge (a dozen extras-dev apps, a custom kernel and manually editing some conf files might have something to do with that;) and flashing wouldn't work because the battery is not full. Luckily I had just bought a second-hand N810 and found this article:)
