NiMH batts for transmitters
 
With the rechargeable nicads being increasingly hard to find, will the new NiMH 1600mah rechargeable batteries work in transmitters? I have a KO EX-1 Mars and the manual does not say anything about NiMH batteries.

It is no problem...........

I use 1800mAH "Monster Cable" NiMH's in my Mars. The manual does state the proper way to charge NiCad's and their "HydroPack"(NiMH's) for the radio. I charge my 1800mAH NiMH's at .4A with a .02 peak detect. Charge the cells out of the radio while they're in their battery holder. I also use five double A 1600mAH NiMH's in my nitro. Need some runtime?

The only problem with using rechargeables in a radio is that the alkalines have a voltage of 1.5v and rechargeables have a voltage of 1.2v. With 8 cells in a radio, that is 2.4v difference.

Rechargable
 
The Transmitter in question has a jack for recharging doesn't it? Mine do . the red light (dead batt) doesn't come on in my TX until I get down to 8.8Volts. I think they are made for rechargables.

I use 1600 Nimh in mine, and it works great and last what seems like forever before recharge.

Jack Smash: your right, but these days radio companies pretty much expect people to use rechargeables. So all the modern transmitters will work just fine with the lower voltage.

I have never noticed any lower singnal quality because of using rechargeables. Heck my new radio even comes with a rechargeable pack instead of a dry cell tray.

The pack is pretty low on the mah, so I'm going to build me a new one with 1600mah or 1800mah cells.
