Review on 🔋 Suuwer Battery Charger: Efficient 8V/12V 1.5-Amp Smart Trickle Charger for Cars, Motorcycles, Golf Carts & More by Charles Galan

Advantages: Robust cables and plugs, long enough for every application. Load management seems to work well. Cons: This device, like most, uses a switching power supply. Unfortunately, their choice of switching frequency is in the audible range, so that a high-pitched screeching is constantly emitted. It's not overly loud, but it's annoying in an enclosed space like a laundry room. Please note ring connectors are designed for 1/4-20 bolts. Most of the extra screws on deep cycle lead-acid batteries are oversized. Of course, you can use the included clamps to connect directly to the main battery clamp.
