re the new victor stream

[brian parker]

Hi, you will have gathered that i have just received my new victor. 
this is about recharging the battery. in the old days, one had to let 
a rechargeable battery run all the  way down before recharging it. 
otherwise, it  would lose some of its charge. so, what about these 
modern batteries. does one hav to wait to let the battery  run all 
the way down, or can one charge up the battery, let us say, when 
there is still ten per cent of the battery left. brian.
