I bought a battery trickle charger today. “What the hell is that?”, you ask? It charges batteries at a trickle – slower than regular chargers, I guess.
Really, I have no bloody idea. Googling it didn’t help, although I spent 5 seconds looking.
I bought it because the weather is good enough to drive the motorbike, but mine failed to start; I forgot to take its battery out for the winter. I have a kick-start, but that didn’t work. I didn’t think the kick-start required a working battery.
