LOST BASE CHARGER OF PHONE.

[silii]

i have an IBM 3900sl cordless phone of which i lost the charging base unit of the hand set,
the phone works if i charge the batteries outside ,but i intend to make a charging base unit
i am prepared to manually make one charging unit for my handset,
the battery is of 3.6 volts.
my question is what type of power supply should i use for making the base set,(ac/dc) and what voltage should i use.
i tried using dc supply of 4.5 volts but it doesnt work.
.
thanx

How did you manage to lose the part that NEVER moves?

Post pics of how you charge it now and I can hook you up with some good ideas
