6 Volt battery question

[Chris in BC]

Is there a need to buy a 6V battery with say 14 amp/hour capability as opposed to one with say 4 amp/hr?

I realize that the battery will flatten faster if the lights are left on without the engine running, but assuming you don't do that, are there any other negatives?

So what bike is this for? If it is for a magneto ignition bike, then you certainly don't need 14 aH for a battery. The battery is only used as a reservoir to run the lights when the engine revs are not enough to have increased output from the generator. I stopped using open cell batteries on my R69S and am now running a battery similar to ones in UPS power backups. I'm running a 5aH battery in my R25/2 which is a battery-ignition bike.

Thanks for the reply Kurt. Sorry for delay, out of town.

Bike is a '67 R60, so just magneto, your answer was confirmation of what I was thinking.
