| 143486 | 2003-05-14 03:46:00 | I thought I had made it clear enough in that "by the way" . Lithium Ion batteries are indeed a different technology . They are very fussy in their charging requirements . I wouldn't use a Li-Ion charger on the other types, and I wouldn't use a Ni-XX charger on Li-Ion . You can get away with a lot in charging NICd or NiMH --- a current limit will protect the battery . You can get away with a fair amount with sealed lead acid . . . just regulate the voltage . "Wet" lead acid are a bit fussier (though I don't know of any cellphones or laptops using them :D) |

| 143488 | 2003-05-15 04:25:00 | Well the phillips & modified DB chargers didn't work. I'm not really supprised. I can sell the DB charger so its only cost me $5 so far. I now know the origional charger was 6v, 400ma. I'm going to wait 'til a genuine one turns up otherwise I'll probably end up spending the $60 anyway and have nothing to show for it. Thanks for the help/education. Brett. |

| 143489 | 2003-05-15 05:33:00 | The one way that will always work is to charge the battery out of the unit. The problem is usually to make the connections. We don't know what is in the phone between the socket and the battery terminals. That could have the limiting and sensing circuitry, which is confused by any external current limiting. :-( I think it is totally irresponsible the way that millions of these things have been imported and dumped (when obsolete ... in about 3 months) ; all with incompatible chargers and battery packs. The overseas funds which are wasted must be enormous. And then we've got to pay for the dumps. :_| |
