Hi Jeff,
I've got a CTEK trickle charger, and the battery has lasted ages. Considering the car only does 2500 miles a year tops, that's pretty good to me.
My issue just now is the brakes on the Faff. They just don't feel that strong, and a bit spongy. It's had new calipers and a bleed, but I'm thinking the master cylinder or servo now. I will try another bleed (including the cylinder as per the workshop guide) and see if that does it. If not, things are going to get complicated.
Bye for now,
Dave.
