Has anyone used the Futaba charger that comes with the 9CHF radio to charge Ni-Mh batteries? I need to slow charge my new virgin 2150 mAh Ni-MH battery. The Futaba charger has two separate plugs, one for the Tx and one for the Rx. It has a rating of 4.8VDC
@ 100MA outputfor the Rx, but it also says for charging up to
4.8V/1000mAh Ni-Cd packs only. Would this work on a Ni-MH battery? How long will it take to charge a 4.8V 2150mAh battery?

Any help would be appreciated.

Thanks,
Gerry

So you're saying that I can use it. I don't mind the charge time. I could just plug the charger into a timer to stop it at a set time.

Have you done this before? What was your results?

Gerry, it will work like furyextreme said. Just put it on the futaba charger and charge for the 25 hours. Thats what I did with my NiMh 2800 pack, but I charged it initially for 48 hours with the futaba charger, and it works great, now I use the duratrax intellipeak digital charger for it.

So, how do you calculate the exact time it needs to charge completely?

I've been using a standard Futaba charger with my Nimh batteries for a couple of years with no problems.
