Non-rechargeable to rechargeable conversion. - UK Vintage Radio Repair and Restoration Discussion Forum

My Roberts R25 runs on a 9v dry cell battery and I would like to convert it to run on a rechargable NMH pack.
Would it be best to use a 7 cell 8.4v pack or an 8 cell 9.6v pack? As the cells are 1.2v nominal voltage it is impossible to get the exact 9v.

Regards

I would go for 9.6V as they will be able to run down a bit more before the set stops working,

Done, now running on 8 x AA cells 2600mah.
Thanks for the info
