Default 9v battery terminal blanks?

Why? [if you wouldn't mind a newbie question...]


My answer would be is you can virtually guarantee the performance of a
decent make alkaline. And I sometimes use a great deal - my personal
record for number of radio mics is 38 at once. It really is rare to get a
faulty battery.

Trouble with rechargeables is they don't maintain the same performance
throughout their life - which makes knowing when they must be changed
rather hit or miss. Plus the fact that most give little warning of running
out - unlike an alkaline - due to the different voltage discharge curves.
So what might be a benefit on a high power demand device like a drill etc
is a liability on a low current one.

Of course if you know they will only be used for a short time - like say a
church service - rechargeables can and do make sense. But this isn't
usually the case for film, TV and conference etc use.
