My 1961 B40 needs a new battery.

The part number of the one currently fitted is LUCAS L6N11A1B  which is a 6v 11ah 130a  spec
There is an option of a LUCAS L6N11A-3A-1 which is also a 6v 11ah but 88a  spec
They both have same dimensions.

Has anyone used the second part number on a B40 ?  Any problems or any advice ?

Many thanks

11 ah is a good electrical capacity for a 6v machine
The other number may well be changed, cold cranking amps   which frankly does not apply as our bikes don't have electric start
