D12 - RADIO - Can I use rechargeable batteries in my transmitter (Tx) ?

Yes, of course you can, and a great many of us do so.

However, there are a few things you need to be aware of...

Firstly, a standard AA Alkaline (non rechargeable) battery provides 1.5V, so if you have 4 AA cells in your radio, it is getting 6v, or if you have 8, it is getting 12v.  Clearly that is what they have been designed to use.

Rechargeable AA cells on the other hand only give 1.2V, so a 4 cell system only get 4.8V, and an 8 cell system 9.6V, so you can see that the radio has les power when using rechargeable cells.

This is not usually a problem, except for the fact that your radio will of course now reach its low voltage area quite a bit sooner than if you were using alkaline cells giving 1.5V

HOPE THIS HELPS ... ?
