Q: After how long really should I hook up the trickle charger? A: Generally, an automobile’s battery discharges twenty hrs following a total charge. It might take longer when you have a larger battery. You'll want to hook up the trickle charger 10 to 15 hours after a comprehensive charge. https://jeffreybosdk.humor-blog.com/31992038/wireless-car-charger-slow-loris-an-overview
