[QUOTE="craig, post: 130653, member: 1959"] I have used this Battery Tender Junior 800mA for a couple of days on two Shorai batteries, one in an Alton charged 47 Rapide and the other in a 75 Norton Mk3. I did a number of workbench Grosset electric starts of the Rapide, maybe 4 or 5, shop fan running to cool, but only 5 min runs. reving the throttle at the last of each run to watch the 8-0-8 amp meter peg on 8 amps. i am trying to eliminate oil leaks and tune Amals. I put the new charger on the Rapide and find that the charge voltage is now 14.8v at the Shorai battery and when the charging is complete, solid green light, remove charger, the voltage at battery is 14.8 volts. However ck the voltage hours later and it is 14.3 volts. The Mk3 Norton Shorai battery does the exact same thing - charge at 14.8v etc. Switch the new charger to Lead Acid and put in on a sealed lead acid and the charge voltage is 13.8v. Just a report you might find informative. [/QUOTE]

The Series 'A' Rapide was known as the '********' Nightmare?
