Ctek or Sterling?

Taken from the Sterling site....

Are there any other benifits from this fast charging.
Yes you also de-sulphate the batteries, this dramatically increases the life of the batteries and reduces the running hours of your engine and fuel costs associated with the charging of the batteries. In fact there are no down sides to this process.

Thats desulphation which I'm almost certain the Sterling will do when necessary eg. I think it's once a week.

In short... most of the 4 stage chargers are suitable to be left on continuously without any damage to the batteries. That leaves one just having to chose which one they want.

I don't doubt that the sterling charger is doing something but fail to see how it can distinguish between the current demands of a discharged battery and a parallel load. Still waiting for enlightenment.....

What does it matter and how can any charger distinguish?

Provided the total demand is within the chargers current rating, current will flow where its needed.

The point being that, as the OP mentions, the Sterling is left connected and on continuously.
I have used a 30amp triple output one for over 2 years and the batteries are always fully charged for when I need them.
The power pack mode, is when the charger drops to float mode - ie it stays at 13.6v. If the demand is low, it switches off for a while to assess the state of charge of the batteries and will top them up to 14.4v periodically and then return to float/power pack mode.

If the batteries were low, then obviously the charger cannot both charge the batteries and supply and external load beyond its rated output. So charging will take longer. If this is an issue, buy a larger version of the Sterling..
