hi. when not in use I keep my bike on an optimser 900 usually when I check the condition of the battery it reads 12.6 volts but last couple of days has risen to 14.3 volts this is without turning on the ignition or starting her up. is this telling me it is 100 % charged or is it overcharging ? can.t find the charger handbook. there is a series of blue lights flashing across the top of screen .many thanks

It will stop charging at 14.4 so I'd say it's float charging and shouldn't do anything until the voltage is < 12.6

Compare with a multimeter though

hi . I was hoping you might reply. so you think all is ok and its not over charging ? strange it always used to sit at 12.6 maybe now its just decided to allow itself to receive a full charge .lol thanks again

sorry . do you mean not to do anything unless it drops below 12.6 ie chuck it in the bin and get a new battery ?

so in other words ideally the charge should be 14.3 volts all the time with ignition key off . and only if it drops below 12.6 bin it ? never a problem starting. touch wood. thanks for advice mate

No. A battery can drop below 12.6 no problem, the charger won't kick in until then.

Doesn't mean the battery is bad
