Optimate Charger and Battery state
I use an Optimate charger with an eyelet lead permanently attached to the battery in my 2001 Spider. If I am not going to use the car for a few days, I plug in the Optimate...It normally shows as charging for a few hours, then I get the green light showing fully charged and on maintenance charge mode.
Recently, however, even after the Optimate being connected for several days, it never gets to the green light "fully charged" state, but stays in the orange "charging" mode.
Any ideas why? The battery is 8 months old. I leave the car unlocked (in my locked workshop!) Could there be something draining the battery enough to prevent the Optimate charging it, like the alarm/immobiliser?
