Thanks so much!! Back to the battery store. :C

Just match the controller to the battery specs.

In use it does not matter too much. Storage is an issue as AGM may not like 2+ hours of absorption every day when already at 100%. Disconnect for storage works good also if the algorithm is not perfect.

There are many flavors of AGM batteries and a generic AGM setting on a cheap solar controller is likely to destroy many of them. You need a programmable solar controller unless you know the charging set points of a particular controller match the requirements of your batteries.

You can get a $12 controller on ebay that has 10 different adjustable things on it, and one of them is the battery. Infact I have a brand new one, but it was only 10 amps, so I had to put it in my spare parts box. But it worked great on a 90 watt panel

If you want the link, I could find it, but so can anyone.

But, at the same time, I been charging AGMs for 10 yrs w/ regular chargers, and the batteries lasted 10 yrs too.

Hi,

Tell us about the whole system? I'd suggest a high end controller with adjustable set points.

Many controllers have a selection button for Wet, AGM, or Gel. The AGM voltage set points on mine are a bit lower in voltage than the Wet set points.

However, some AGMs are spec to use the same or higher? voltages. Each brand /type of AGM seems to be different. First find out what your particular AGM has for charging specs, then compare with any controller's set-points.
