    CTEK DS250 performance.

    Before setting off a 4 hour motor way trip I took note of the state of charge on my leisure battery, it was at 20% and reported as in perfect health on the app. I thought by the time I got home it would be at least up to 75% or so. To my horror it was at 22%. 2 effing amps in 4 hours, which...
