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 use a CTEK_MXS_5_0 (Swedish) .

It charges at up to 5 amps.
It has an option (pulse charge currents) to renew a battery (shakes up sulfates).
5 Amps is max, overnight is enough, so estimate 3 amps for 12 hours is about 40 watts.
Trickle charge to full (7 LED's chart progress and the last one is green for full).
I only need this once per week at most, normally less.

Bonus:  The DC ends in a connector, one set of Alligator Clips to attach to battery, one set of eyelets to make a permanent connection to the battery. One car has the battery in the back, I attached the eyelets and ran the wire up into the rear compartment of the station wagon. All I have to do is plug in the charger (DC and wall outlet).

I purchased a spare set of eyelets with the CTEK connector and installed it on my sedan.

So one charger does both vehicles (not at the same time of course).

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.
