Ctek Mxs. For my needs, the ctek mxs 5.0 is just perfect. About the ctek mxs 10.0 view the manual for the ctek mxs 10.0 here, for free.
This is quite a nice charger, it has a 5a capacity, readouts to show what charge mode it is on, an agm function and a recondition function. Stop throwing money away on dead batteries with ctek. If you are worried about the safety of it, don’t be!
