Best yet for my pre war Classic Cars

This battery ended my trials and tribulations for a 6 volt battery for my classics ( 1929 Packard and 1930 V16 Cadillac both +ive ground) . I bought a pair in 2012. One of these is still starting the Cadillac V-16 and charges to capacity, although it is now showing age. . The other twin was left untended for almost three years and stopped charging. So the battery left on the shelf in storage died in about 5 years, the one in active use is in its 7th year. The only issue now is that these are not available outside of the USA and sitting in Pakistan, I have not found how to buy and get it delivered. Highly recommend for classics on 6 volt system.
