pdficon.gif (232 bytes) alkaline_battery.pdf 433 KB N/A This is a compilation of all the technical pdf files from the Duracell web site on their standard alkaline batteries (D, C, AA, AAA cells).
pdficon.gif (232 bytes) slb_techmnan.pdf 774 KB N/A This is the technical manual for Power Sonic's sealed lead acid battery products.  A listing of all there SLA products was added to their original tech manual.  Spec sheets for individual batteries are available (in pdf format) from the download section of Power Sonic's web site.

Tools:

Failure Modes of Simple Pressure Vessels Library: This is an Excel File and a Mathcad file, either of which can be used to estimate the pressure at which a simple cylinder will fail by yielding and buckling. And for estimating when a simply supported end cap will fail by yielding.

For a Detail Description of the These calculations go here.

The user enters the material's properties (Young's Modulus, Yield Stress, and Poisson's Ratio) and the files return plots of Thickness/Diameter ratio (allowing use with any size cylinder or end cap) vs. Depth.

To prevent failure the Thickness/Diameter ratio should be thicker than those specified by the curves (i.e. there is NO safety margin!!!)
