I am in the midst of upgrading my battery bank following the instructions in the 
orum archives.  FYI, based upon cost / benefit ($200 each) I installed 2 
nterstate SRM-4D lead acid batteries for the house bank providing a combined 
apacity of 410 Ah.  (I know, they are not a pure deep cycle battery, but 
eadily available without paying huge shipping charges)
 am ready to purchase the dedicated start battery.  I am looking at a Group 24 
11x 6 7/8 x 9 1/2 inch) lead acid rated at 800 CCA and 1000 MCA.  Looking at my 
erkins shop manual, the required starting current is 540A.  Does this seem 
easonable, or am I reading the spec sheet incorrectly?  Also, assuming 540A is 
orrect, I have been looking for a fuse to install at the battery "+" (Blue Sea 
EGA SEA fuse block p/n 5001), but it seems that 300A is the maximum fuse (per 
efender Catalog).  I think that this fuse rating would be inadequate, any other 
uggestions?     Alan;  Hull #67;  Holland MI; launching last week of April or
