Awesome! Miraculous!

I tried the CTEK, without much conviction, saying that at worst, it would serve to maintain the charge of my car during the week.
What a slap!

I take out the battery, the device very simply branch (I have no concept of mechanics, am particularly clumsy and have no talent for DIY) and I am what is written on the manual to perform a "renovation / regeneration "of the battery (their term beyond me).

The next day I come back, I'm still the procedure, and I put the battery in the motorcycle: MIRACLE!
It restarts clockwork.

Really amazed! The tests found here and there before buying on the net seemed to me wacky, but I can confirm that this charger works extremely well.
