Re: Battery change

Just a thought on batteries:
In my 1938 120, I've recently replaced my lead/acid battery.
The 6V 830 CCA lasted ~2 years before a growling slow crank.
The physically larger replacement battery is 6V 800 CCA (cold cranking amps) and is very grunty. Reserve capacity seems to be the key.
I have previously used 800s and they typically gave about 6 years under the same conditions, hence the change back.
My conclusion? It's hard to beat size.
The fit in the battery well is close but ok, though the battery recommended by Packard Motor Co is much smaller.
Weather conditions here are generally 10 to 30 degrees C.
