Reply to an old post but here is what ctek had to say when i popped the question of using a ctek(5.0) on an agm battery


HI

We are probably one of the safest chargers on the market and our chargers does not damage batteries.
But you need to always follow the recommendations of the battery manufacturer.
Different batteries have different requirements.
MXS 5.0 has different programs for separate use for each size and type of batteries.

Charging with CAR mode is in 14.4V, with higher rapid peaks in desulphation mode but ONLY if the battery NEEDs it.

reagrds, CTEK

Hello sir/madam, please can you verify if my CTEK will damage an agm battery ? I read the specs and reviews of agm and says charging at over 14.4v can cause damage, and the ctek 5 I see does go 14.4,14.7 and peak at 15.8v in some cases.


Any feedback much appreciated
