How much do last the batteries in a Grado RA1?

[greenhorn]

Yes, it depends on plenty of factors, but a rough estimation would be more than enough

Approx. 40-50 hrs on Alkelines.

Expect ~10 hrs on NiMH cells.

Same here. About 40-50hrs on alkaline. Closer to 15 on NiMH

I used to get about 25 hours on NiMH when I had the RA-1.

NiMH will depend a lot on how often it's used, because they have a self-discharge rate, something like 1%/day. If you only play it for 4 hrs a month, you might only get 8 hrs total from them. The capacity of NiMH varies, older ones were pretty low, 150 mAh, but newer ones are in the 250 mAh range.

The one I use to have way back gave me about 35-45 hours.

The RA-1 is one of the amps that I am considering but there seems to be no pictures of the underside or the battery compartment. Do batteries just hang loose in the unit?

Thanks everybody!

Agent69: the batteries are in a small compartment below, with a lid which closes with two screws (you can screw/unscrew them by hand).

I get 100+ hours. I am wondering if it is because I listen at remarkably low volumes?
