Constant current battery chargers

[Snowman9000]

I don't have AGM batteries but could someday due to the horrible location of the battery (soon to be two) on my mini MH. I read some AGM manufacturers' instructions and they say clearly do not use constant current chargers. Use only voltage-regulated or -limited chargers. (With temperature compensation too.)

I do want to upgrade my 7345 to something better. My specs are to get something that has the best performance off my Onan 4000 microquiet, and also can be used for AGMs if I were to get them.

Are not all the converter chargers voltage-regulated or -limited? Even those which are "constant current"? Looking for someone to elaborate on the distinctions as they apply to the voltage concerns of the AGM people, and maybe describe the differences between two prominent examples. Thanks.

(I think the PD's are voltage regulated and the IOTAs or Boondockers are constant current???)

Never seen a constant current battery charger even in automatic chargers. I will go the PD route if our 20 year old Magnetek converter ever stops humming.

AGM batteries can be charged that a much fast rate than flooded lead acid deep cycle batteries but most want the voltage limited to 14v range unless equalizing the best I remember. We only own about four AGM's today and use both regulated and unregulated chargers OK so far.

Read what your future AGM makers have to say and go from there. AGM batteries are not as fragile as some think they are in my experience.
