What is the voltage drop on the battery when you transmit?

> Hi All,
> I recently purchased an old Hercules II power amp. I'm running it on a
marine deep cycle battery that I got at Walmart (115AmpHour- biggest one
they had), with a 15amp charger.
> The problem is that the amp doesn't appear to produce rated power on all
bands. In fact, driving it with a 100W transmitter, I can only get the rated
500W output on 10m. On 40m and 20m I can only get about 300W out. This is
either into a dummy load or the antenna tuner.

should be.

thought I'd first see if anybody on this list had some knowledge about this
they were willing to pass along. Does anyone out there have experience that
might be of help?
