Which trickle charger / conditioner?
 

I've been told Ctek are the ones, having looked at their website....which one?! For the CSL.

CTEK or NOCO. Latter is the newer challenger brand (US design verses Sweden who are Ctek but both made in China). NOCO has benefit of also doing AGM+, 24V Lithium Ion and a 15AMP quick 'jump' start mode and 5 year warranty.

I run both

CETEK MXS10 or NOCO GS15000 and both good.

My pal has the NOCO GS26000 which he uses for his garage. It a beast.

Kindest,

J.
