Optimate graphs

Yesterday I bought a gizmo for my scooter battery. My scooter is a good few years old and thus isn't in the best condition it could be. As soon as the temperature hits sub-continental (i.e. if it's not really sunny), the battery dies.

So I bought an Optimate. I'd had them recommended to me.

This image was on the back and it gave me a great sense that this gizmo knows exactly what it's doing. I can tell by these two graphs that I've got a quality product. I have absolutely no idea whatsoever what they mean, but that sort of doesn't matter. They've gone to the trouble to put them on the packaging so it's good enough for me.

I'm just glad the instructions said "Plug it in and connect and the Optimate does all the work for you."
