Best types of batteries
(OP)
So quite simply, what is the best kind of battery for say a digital camera. I was taught in school that it was alkaline.
What do the pros use?
Also, is the good old lead acid car battery still the best or do the new spiral core batteries have any thing more to offer?
Thanks

RE: Best types of batteries
From a simple number of shots perspective, alkalines are probably better, since the low-batery sensor is tied to the voltage it receives and alkalines tend to start at a higher voltage.
But, you can also use an external battery pack to keep up the shot count and minimize the recycling delay for flash photos. Actually, pros often use battery packs for their camera flashes, anyway.

Many of the compacts digitals have proprietary battery packs that use Li-Ion for decent capacity from small size

after you charge it, and before you run out to use it.
Alkalines dont like high current draw and reports say
some more modern digital cameras and alkalines dont mix.
No battery life at usable voltage with the higher current draw.
NIMH tends to self discharge faster than NiCad technology.
Nicads (quality ones) like to be worked hard and give
good life if charged hard and used hard.
Most other technologies prefer shallow discharges
for good life span. Nicads want heavy usage.
You can not get a battery to to better than designed,
You can do a lot to cause early death.
Over charge, high temperatures. Deep cycling...
Best to match your choice of cell technology to
your personal type of usage.
I use NiMH and try to plan a charge session before I go
for maximum power.

in terms of capacity:
Alkaline AA is about 2800 mAh
NiMH AA is about 2100 mAh
NiCad is about 1000 mAh
The current discharge capacity (the equivalent internal resistance) varies between manufacturers. On my camera the Panasonic NiMH performs better than the Energizer NiMH, even if it has a lower capacity spec. But with a camera that draws less current, the Energizer might be better.
