Gentle Friends,
Now that our favorite Forum is back, I thought I'd report the results of an interesting issue Dreamer raised, battery life while using a PA. A while back she tried to put some numbers on the issue we've noticed (the Solo battery still needs to be charged from time to time when you use the PA) saying something like 'it goes down at least 'one light' per day of heavy use'. PA Queen she is, she'd surely know?
So I had to 'crack' the Solo once again for other reasons so I decided to check it out. The JST connectors used for the battery can be disassembled on the battery end easily. If you look carefully you'll see a little rectangular tab from the pin sticking up into a slot in the plastic retaining the pin? Pressing it down a bit lets you slide the contact and wire out. Then I inserted a piece of fine copper wire into the connector and out the slot, folded it over, and reassembled it. Then I could clip my DMM (in 10 Amp current mode) in series (one lead on the pin, the other on my test wire).
In broad terms about half an Amp of battery is needed to run the heater in PA mode. When the heater light is off, current demand from the battery is low (as you'd expect), .01 Amps, the minimum reading on my meter. However when on it jumps to .5 Amps or so. Without the PA, the current starts out 3.0 or so and rapidly (over several seconds) drops to about 2.5 as the heater warms up some. In PA mode about 2 Amps of that comes from the PA.
So, in broad terms, using the PA gives you 5 times the sessions between charges. Next time someone stops you in the street and asks, you've got the answer........
Good weekend to all, the days are already getting shorter, best to make the best of the season. For me, that means filling the bird feeders......I think I'll take the Solo along for company, never know where a trip the garden might take you.
Best wishes,
OF
