My engine start battery in my 75 Avion is dead and this will be my 1st time changing it. I found that it has both on the top, and the bottom a plastic spacer to allow it to fill the same height as the front house battery so that the battery mount top strap sits level over both batteries.
The one I pulled out is labeled 34/78. I see from this chart: http://www.batteryweb.com/bci.cfm that it is 7.9" tall. Also see that various batteries in the group 24 and 25 range have the same footprint but are taller, negating the need for the plastic spacer(s). I know this a very noob question, but thought I'd post none the less.
Is there any reason to stick with the 34/78 with spacers? Would a taller battery be preferred? How many CCA's are considered optimal?I am in CA and expect to rarely be in low temperature environments. It occurs to me that since there is the 'House' battery there with it's boost switch that the lowest (smallest) adequate CCA battery would be fine? Note I only need the top mount terminals.
I have only O'riley and NAPA locally.
Thank you for your input!
Cheers,
Dave
