REFLECTOR: Wire (typo?):pissing contest

Thu Feb 17 20:01:05 CST 2005

Thank you Larry for correcting me.  I use the 27 amp hr 925 cranking amp
Odyssey PC925MJT Gas recombinant "Dry Cell"  See stats at this link IF
interested.  I have been very pleased.

Dave,

Rene' mentioned he was using a RCG battery as in lead acid.  Li-Ion 

batteries have a much better power to weight ratio than lead acid
batteries. 

However, a 900 Amp Hr Li-Ion battery by your spec would still weigh 225
lbs. 

What's your point?  Concord probably rejected the deal because they
thought 

they might have trouble selling a $1,000 + aircraft battery.  The price
is 

just a wild guess but I do know that the tiny (Li-Ion) battery in my
cell 

phone sells for $45.
