See if you could get me couple of American ones. (IMG:https://gizmondoforums.com/forums/style_emoticons/default/wink.gif)

@FR4NK5T3R: plz tell me how long it holds charge (or how long it can power the giz)

cuz i´ll immediately buy some - mod them and then I´ll sell them on the forums or on ebay (of course not for too much money)

Slight teething problem at the moment.

Put the Gizmondo in the car cradle to charge on the way home and rather than a charging battery symbol I got a symbol for a charger lead and an exclamation mark so I guess it's not going to charge.

I think it may be the thermistor if it is one. I got the battery from Ebay really cheap. I was slightly suspicious when I put both batteries in the fridge and whilst the Gizmondo thermistor had changed to 20k the DB-L40 stayed the same at 10K. I thought the Gizmondo would accept it as an OK temperature but obviously there's more to it. I will add a thermistor to the adapter and leave off the middle terminal to the battery and see what happens.

or maybe just maysure the normal value (in ohms - with normal room temp) and put in an normal resistor with this value

Will that not just overcharge even when the temp goes up?

Lithium is charged a bit like Lead Acid. You keep filling it with constant current until the cell reaches a certain voltage then you just maintain that constant voltage. The current will gradually drop and when it reaches a certain level you stop. The temperature is mainly there to prevent any charging outside sensible ambient limits and for emergency stop. So best to use a thermistor but you could use a fixed resistor.

Glad you're working on a back up plan in case my scheming comes to nothing (IMG:https://gizmondoforums.com/forums/style_emoticons/default/smile.gif)

A few pics of the insides of the Gizmondo and Nokia batteries (phone camera isn't great at doing close-ups so the detail isn't great I'm afraid):

Nokia & Giz Batteries

The first few is just getting the Giz running on the Nokia battery, after that it's the taking apart of the Giz battery and the last one is just me beginning to peel open the Nokia battery.

Another thought - I've got tons and tons charger cables for various things: phone, mp3 player, gizmondo, pda, etc and would very much like to consolidate a few of them - I reckon the Nokia and Gizmondo charger are the same - just have different size of tip. Using an AC/DC adapter with exchangable tips to charge my Gizmondo anyway to going to see I can them to work on the settings and then if they do look at cracking/removing the plastic tube around the power connection on the Gizmondo so the Nokia charger will fit into it. Well... it might work.

Good job!
Fingers crossed this gets somewhere!
If a new battery was made I'd opt for hight MA to help battery life out.
