Been using NOCO charges for a few years, have a pair of twin NOCO Genius 2, 2 amp chargers on the garage wall for the day bikes, ideal for all year round maintaining. For battery recovery I have an older version of the new Gen 25amp maintainer, pricey but has recovered a car battery from 3.5V. Andy
Got a double outlet NOCO on my wall. Really well made and pretty good at recovering almost dead batteries. Got mine from Halfords using my discount card.
Mine came with my Scrambler XE as the previous owner kept it in an underground car park without access to a charger/tender. Used once to bring my van back to life. Started on the button. Great bit of kit.
Battery charged, sitting at 12.4, no start, tested the starter solenoid by bridging the contacts, started to turn the starter motor, too much sparking for my liking so I didn’t hold the bridge long. Will order a new solenoid.
