Quote:So I am pretty sure that the old battery is gone altough it is only 1,5 years oldĀ [img alt=:eek]http://foc-u.co.uk/Smileys/efocicon/shocked.gif[/img]Now I am completely sureĀ

When I removed my nice yellow battery from the bike the voltage was 9,8 V.
I charged it with my Ctek MXS 5.0 in bike mode.
When the Ctek showed that charging is complete I disconnected it.
Voltage on the battery was only 12,62 V. Normally it should be at least 12,8 V direct after disconnection.
After one hour the voltage dropped to 11,69 V....
