i'm looking for a trickleloader for a car battery
model Varta 12V model E11 - 64 Ah - 640A
what should be the properties to look for?
as i understand, some have allso the option to renew a battery, from (near) dead; that of course costs more
and how much current does it use, say per hour or per day?
I chose the CTEK (last item) because it was recommended to me at the Interstate Batteries shop where I purchased the unit. I have been very satisfied with it.
The Optimate looks similar and probably is fine but I do not have any experience with it.
