battery theory (NIL Audi content)

[Douglas Frank <frank@zk3.dec.com>]

Haudi,

A friend of mine with a big honkin' sailboat (did I say friend?  I hate
his guts) wants to add a third lead acid battery to run his electronics
a little longer.  His trouble is, there's too little room for a third
batt. of equal capacity; so he's decided that he'll just wire in one that
does fit into the locker.  In other words, he'll have three batteries of
unequal capacities wired in parallel.

I bet this is a bad idea, but I can't convince him not to do it.  Can
anyone point me to some battery theory?  I'd hate to see him burn the boat
to the waterline (until after I get a ride, anyway).

Thanks, and apologies for the WOB.
