So You Want To Run Your 'portable' AM/FM Shortwave Radio On Batteries . . .
Many people know this, but there are likely some that don't.
9 v. alkaline batteries have six 1.5v. cells inside the rectangular can (smaller than AAAs) that are welded together. This is why 9 volt batteries (at least in my experience) are somewhat unreliable/high failure rates. It just takes one of those internal 1.5 v. cells to fail....or a bad weld or two. I assume a NiMH rechargeable is the same construction. A "9 V. rechargeable" is only 7.2 volts....so you are giving up a lot there. For sure, you wouldn't want to use these in smoke detectors.

Alkaline Batteries really are the best.
Howsomever,ayyboot a week ago on the enterhernet,I read that Panasonic has developed a Li-on Battery that can not short out and catch laptop computers and houses on fire. cuhulin |
