I did search for this answer, but I have one of the newer style PCCs and am not sure when they hit the market so some of the search results may no longer apply.
I got my first Bloog today. I did read the directions but I am a bit confused about charging the PCC case battery for the first time. The instructions show a picture called "PCC Battery Charging Condition" that seems to indicate that the PCC case, absent a battery charging simultaneously, uses the entire bar graph to indicate a full charge. My back light and the graph are turning off before the entire bar graph is showing.
While I'm at it, are there any "battery memory" issues I need to be mindful of with the PCC battery and the Bloog batteries? Will I hurt my battery charge-life if I don't disconnect them as soon as they are fully charged? I have senior memory disorder. I can remember what happened 40 years ago but can't remember what I went downstairs for by the time I hit the bottom step. I can be counted on to forget I have a battery charging.
