Rayovac * battery product guides for a range of batteries - quite useful. Reasonable amount of technical information, specs, graphs etc Very nice information sheet on Alkaline Rechargeables (24 pages) The Primary Battery pdf gives information on discharge times and capacities to various end-points for a range of their cells. A look at their comparisons of their "Lifex" technology Lithium cells' performance compared to generic Lithium batteries could almost lead one to believe that there is more to the brand of a battery than just a fancy marketing name. Info below * - I have no association with Rayovac whatsoever (have never even used their products as far as I can recall.)
