Subject: Re: Battery advice for LG45
I am no expert on batteries but surely you need to look at the "CC" (cold Cranking) figure to see if the batteries will be sufficient to start the engine. From memory I think you should need cold cranking of 600 CC plus ?
The AH rating is something different and relates to the capacity of the battery (Amps per hour) i.e. 65AH is 65 amps drain for one hour. If you therefore left the headlights and a lot of other things on totalling a discharge of 65 amps (assuming that the engine is not running i.e. no charging) then at the end of one hour the battery would be flat.
Therefore ( and I stand to be corrected by more knowledgeable members) a 65AH battery should be fine for an LG45 but you need to look carefully at the cold cranking figure.
