High Rate Application with Primary AA Cells

High Rate Application with Primary AA Cells

High Rate Application with Primary AA Cells

I have an application that requires a high rate current up to 8A for 1 second numerous times. Most primary cells are not rated for that high pulse current. Is there a way to overcome that. Could I use a capacitor in parallel to provide that current?

RE: High Rate Application with Primary AA Cells

What do you mean by "not rated," as opposed to "not intended?"

A typical AA cell can dump 10A in a short circuit. The main issue will be that its capacity will be substantially de-rated.

LiPO batteries designed for high discharge RC applications are readily available: http://www.ebay.com/sch/i.html?_odkw=lipo+20C&...

1 amp * 1 second = 1 coulomb time say 100 times and assume no more than 0.2 volt droop --> 500 farads
