I note this charger for its ability to charge the battery when it is very cold. Its landmarks charge 0; 25; 50; 75; 100% indicates the health of your battery. Load the clips are very professional. The connectors to put (in my case motorcycle battery) are very tight. The transformer is more costal, it loads at an average of 1.1 amps which is very important for small batteries garden, quad, motorcycle, etc. which does not damage the internal components of the batteries. This product is not designed for loads of car battery but allows a holding load possible.
