The battery is about 22 months old but has done very well so far. It is oversized in terms of the Amp Hours needed and so is the solar panel. In this manner it can easily survive a few heavily clouded days before the low voltage disconnect would shut down DW. The LVD will shut things down around 12.1 volts, approximately 55% battery capacity.




Thank you for all of your reports!

That was a good design decision. Top marks, and thank you for giving us such a great signal to listen out for, even though I know that wasn't the primary intent!

Looking over my notes it seems that DW was getting weak around the 3rd week of September. Now it is great copy at home, even can be heard on the NRD-525 with an untuned, RX-only antenna.
