Re: CD47 charger


 

Clint,

The charger the correct charger is for the Li-ion battery.
A/ it was purchased as a Li-ion charger
B/ The contacts are for Li-ion (contacts for Nimh
are reversed) E.g the Nimh battery would not 'fit'
C/ Everybody (Amazon and Ebay), sells the cd-47 as the li-ion charger.
Some chargers have 4 contacts, some 3, all are listed as Li-ion.
I suspected that the 4 contacted chargers would do both types, but that seems to be wrong.

My (new) LI-ion charger has double contacts on the left side and my ancient
Nimh charger has them on the right side, no mistake to make.


My Li-ion charges correctly to 8.1 volts (a little low).? The supplied
wallwart will charge it to 8.4 volts.

The Yaesu CD-47 was designed for NiCD and NiMH chemistries.

Li-Ion requires a much different algorithm to properly charge packs properly.
