I have tried them in the past, they are 2.4v instead of 3v to start with,
they are expensive
compared to normal batteries and you need a charger
which uses power which has to be paid for. Never last as long as
a proper battery,
get lost or thrown out by mistake. If you live in a situation like myself
where there are probably 40 to
50 batteries installed in various devices toys handsets mice etc, it soon adds up. I prefer to just bulk
buy Duracell from somewhere like 7 Day shop
Strange that you should say that,
I once worked with a professional photographer
and he would only ever use a brand new battery and take spares every
time he went to work,
if he had only used it for
2 mins he would bin it , I used to pick them out Duracell 95% left.
I've got a couple of small solar-cell-powered floodlights [with motion sensors - so the light comes on when walking nearby]. Light energy from the Sun is converted into chemical energy within the rechargable batteries housed inside the body of the lamps, and this 'free energy' then lights up the array of LED lights in the floodlights. No bother at all.
I've been using rechargeable batteries for my photographic work for my cameras and flash equipment for the past 10 years. Would never dream of using anything other than rechargeable. Always buy top quality batteries and top quality battery charges, never ever had any problems.
Umm, I can see why this was posted in "Speakers Corner" in the first place! Technically and financially I would go for rechargeable. If 2.4V and not 3V is the issue that you can get Nickel Zinc batteries as these are 1.6v each. So it seemed to be more of a campaign to use Duracell for convenience for convenience sake so should have been left in "Speaker's Corner"!
