My CBR's battery was well and truly flat after I came back from holiday. I had it on charge on a variable regulated power supply, but it does not seem to want to charge up to 14.4 volts ( measured the current at 600mA after prolonged charging ) Is it time for a new battery ? My understanding is that the current should drop below 100mA at 14.4 v , then you can switch the charge to a 12.5v float level. What voltage / current is the bike meant to charge it at ? Simon
