Can someone guide me to somewhere I can find performance comparisons on Duracell/Energiser/Eveready ? For the likes of Maglites, radios and whatever is comonly used.

I can see the general specs on rechargables but when I seek, on a search engine, free advice (under Battery) I keep getting some legal guys on how to sue your husband for assault.

I have looked for similar statistics, I couldnt find a basic Amp-hour figure for Duracells

A reason may be because to a certain extent the figures are academic, I'm not an expert but I think the energy output of a certain battery technology depends on the current you draw from it over its discharge cycle

If you look at some of the Duracell ProCell data sheets here

http://www.duracell.com/Procell/productdata/#

You can see that for example a Duracell Procell 'C' cell looks like it varies from between 3.5 and 6.5 amp hours depending on the power drawn from it.

There are some specialist battery technologies that have a very high power:weight ratio, but only if they are discharged at a low current. High current draws make them dangerous/ explosive. They use these in things like dive computers

Thanks guys,

There is a world of difference in performance of different types under different loads. More important than brand is the matching of equipment to the battery.
