| 330979 | 2005-03-05 10:11:00 | Hey, I got a nice Gtran 4020 from an ex-rentals bin at a Telecom store (along with loads of other phones and stuff, all working nicely). But I don't have a battery or charger for it. I managed to get some other phones charging off various homemade devices (including 5v rail of my PSU). But this is a bit harder to wire up to. I can't seem to find access to a battery or charger anywhere. Anyway, if anyone has time, this phone and a multimeter, can ya do me a favour? Measure the battery voltages, tell me which terminals of it are the power, and what polarity it is. If anyone has an unwanted charger for this phone, I would be very interested - cheers. |

| 330980 | 2005-03-05 18:18:00 | Charging batteries using the wrong charger can be VERY dangerous - Godfather will have more details I think, but I wouild strongly advise against home-made chargers unless you know exactly what you're doing. | somebody (208) | ||
| 330981 | 2005-03-05 20:39:00 | That's not my idea - I want to hook up a battery of a different phone to it, to check for sure that it works before buying a battery/charger. | george12 (7) | ||
| 330982 | 2005-03-05 22:11:00 | Dunno if this what you want or not but here goes 3.7v Li-Polymer Battery I can post a pic if you want (shows the polarities) Looking at the back of the phone: neg. on left, pos. on right I have a spare charger & battery from my sons broken phone, but due to the cost of replacing them I'm hanging on to them in case I break mine |

| 330983 | 2005-03-06 02:13:00 | Cheers mate, I'll try putting 3.7v across how you said, and see what happens. Edit: The pic(s) would be most helpful if that's not an inconvenience. |

| 330984 | 2005-03-06 03:02:00 | Yuss, the phone works. Hooked up 3.6v from a Nokia battery to it (soldered wires to it), and it turns on and says "No Battery". Because, I have just given it the voltage and nothing else (the other two pins obviously). But it's ALIVE which means it's worth getting a battery and charger somehow. | george12 (7) | ||
| 330985 | 2005-03-06 04:28:00 | Oh - I see. In that case it's not so much of an issue. | somebody (208) | ||
