Icom Radio charger Question

Seems no one knows

No know what Resasi???????????????????:eek::twitch:

I plug my charger into the radio and it charges the battery.

Chris question was up a bit and no one responded. Tried deleting but it stayed hence the comment.

I took my Icom A6 over to UK and we have 220V 50HZ. I had a 110V 60Hz two pin charger. Output 12VDC 200mA BC-110AR

Out at the airfield the radio dies and I was offered a UK 240V 50 Hz 3 pin Icom charger BC-02-UK however this one gives 12VDC 300mA.

I do know that I cannot operate the radio when using the charger as it will damage the radio, not that one usualy does that. The question I had was what will charging with an extra 100mA effect the battery.

I called Icom here and was given the info about not switching it on, and that it would charge, however they did not seem to know what the effect of the extra 100mA would be.

It is an Icom charger and the temp and time limits are all being observed.

no effect, it will charge a bit quicker.
ni-cad batts are charged using constant current ( the charger voltage will change to maintain the current at a constant value).

If you are really worried about the 100ma extra you could rig up a 7805 Regulator to provide 200ma output

or you could rig up a LM317

or google "7805 constant current"

Thanks Padraic. That has reassured me. I will monitor the battery temp and be careful about charging time.

They do emphasize no more that eight hours max but give one no means of telling when it is fully charged.

This circuit is one I used to use to charge my R/C gear with my car cigarette lighter socket at the flying field. it would be a simple one to use to give your radio battery a bit of charge while driving to the airport.

with a 7812 the resistor you need for 200ma is a 60 ohm resistor (a 56ohm and a 3.9 ohm in series)

Just FYI... I have an old ICOM "quick-charger." It sends 500mA in "get-er-done" mode, then backs off to 75mA trickle to sustain.

*JC*

Thanks guys, feel better about this already. Just didn't want to wipe out my new radio. They cost a lot more over here.
