Review on ⚡️ GOOSUO Automotive Trickle Charger for Car Battery - 12V Battery Charger & Maintainer for Cars, Motorcycles, Lawn Mowers, Boats, Tractors, ATVs, RVs, SLA Wet AGM Lead Acid Lithium Batteries & More by Jaye Cleveland

I love the fact that I can charge small batteries slowly and larger ones quickly. However, I plan to use the slow tuning on large batteries for better battery life. Slow charging is best for batteries in the long run, of course fast charging works well if you don't have time to wait for it.
