Neo, don't know if they use the same batteries in your cars in the UK as they seem to in the US and down under, but in a thread that was on the US forums and most of us in Kiwiland, most change their battery/or it just dies at about 5 years, so might be a smart move so not to get stranded. Changed my Zeds battery at 4 years 5 months I think, but then I drive with my headlights on all the time, so drain the battery slightly more.
I think Bronzee's is the oldest, then it could be mine
Maybe. 5 years, 5 months, since I purchased the Zeddy new.
