I just bought a 900 cca battery at Costco to use as my starting battery
($58,100mo). My plan is to put that battery in bank 1 and to purchase
two Trojan T105s for bank 2 (hooked together in series of course). I
have the standard "1,2,both" switch. My motor is a Yanmar 2QM15.

I have an alternator which was recently rebuilt, supposedly to put out
60amps, and according to the ampmeter puts out about 35 amps at max. I
have a shore power West Marine 5 amp charger. I'm hoping to not have to
upgrade anything else due to low finances, especially not an expensive
new alternator!

Can someone show me the figures as to what problems I will have if I
stubbornly refuse to upgrade anything else? How long will it take to
charge them with the motor or with the shore power?

Last question, Do I have to do something unusual to hook everything back
up? Can I just charge both banks at the same time as I did before or do
I have to charge the banks separately?

Thanks so much for any help!!
