Subject: [Waverley ARS] Batteries: convert CCa to AmpHours

 

Dear members,

 

As Hawkesbury Canoe Classic approaches, the need to have portable power made
me look around and see what batteries I had available. 

One of the batteries I have is a deep discharge lead/acid battery rated at
640 CCA.

 

My question was, what's that in amphours?

 

I found this website via google:

 <http://www.chem.hawaii.edu/uham/bat.html>
http://www.chem.hawaii.edu/uham/bat.html

 

The formulae stated reduces to:-

 

Amphours=(CCA/10)+16

 

So a 640 CCA battery is actually 80 amphours.

 

Just thought I'd share this little bit of knowledge with all of you...
