Hi there,
I have recently purchased the above regulator for my camper and will be purchasing About 200 ah of Century AGM batteries.
The above regulator only has two options re batteries.
Gel batteries are: Boost at 14.4 volts and Float at 14.1
Wet batteries are: Boost at 14.4 and float at 13.9 as
well as an equalisation charge at 14.7 volts for 2 hours every 30 days.
I have always read that AGM batteries should never be placed on equalise but the following century battery data sheet appears to show that this may be ok?
http://www.batteriesdirect.com.au/shop/product/22743/c12-100da.html
I would like to know which setting would best suit.
Keeping in mind that the gel setting at float is .3 volts higher than Century recommend.
Is this an issue?
Which way should I go?
Thanks
Chris.

even without looking for the Century tech documents direct, looking at the spec sheet you link.
It specifies a float charge at 13.6 to 13.8 volts.
and
Equalisation or cycle service at 14.6 to 14.8 volts
with the controler you have your only reasonable option is the wet battery selection.
Don't beleieve everything you hear about AGM batteries, there is such a variation, you can only rely on the manufacturers documentation.
From memory Century have a document on use and management of their sealed lead acid products that includes AGM.

Interesting....and for others reading.
The issue with temperature and AGM has been raised.....note that the spec sheet says...." warranty void is mounted under bonnet".
