Rechargable batteries and information

My pocket sized DAB radio eats AAA size batteries like there is no tomorrow.

Maplin are selling so called 'Hybrid' rechargable AAA 800 mAh at four for
£10.99. Whilst Argos are selling four 'ordinary rechargable' AAA 850 mAh at
£5.99 (and 1000 mAh AAA at £14.99, which seems a big jump in proportional
price for another 150 mAh ? )

I don't know whether the Sanyo Eneloop batteries are the same as all
other hybrid batteries, but I find them so much better than standard
NiMH batteries; though as you have pointed out, the rated capacities are
similar. The USP is that they hold their charge, but in my experience
they seem to be better at holding their full charge even after months of
charge/discharges. These cost about 7 pounds for four AAAs from amazon,
but IMO well worth the price premium.

Does anyone know what the technology of hybrid batteries is? I don't
mean what they do, I mean the chemistry or whatever.

"Hybrid" appears to be a marketing term for some brands of low
self-discharge (amusingly abbreviated to "LSD") NIMH batteries.

See http://en.wikipedia.org/wiki/Low_sel...e_NiMH_battery
and note some of the brand names.

Same chemistry AFAIK (and therefore exactly the same voltage).
Just different construction.

I get the impression that the Vapex Instants I use (another make of LSD
Ni-MH) are more robust than many ordinary high capacity Ni-MH.

Why "hybrid" then, usually means a mixture of techniques or technologies, much like this
random cross-post

I suspect Typo Unross call there Battery Hybro

Marketing. It combines the rechargability of rechargables with
the long shelf-life of ordinary batteries. That's close enough to
"hybrid" for a marketroid.

That's my understanding of where is came from too.

It's only a marketing name, engineers call them LSD NiMH where LSD stands
for Low Self Discharge.
