Batteries Lead Acid vs AGM
Since we are new to RVing I have questions for which I appreciate all comments. Would like opinions on using AGMs or lead acid for House Batteries bearing in mind that AGM's like to be charged at...

Hi,
There are a few more negatives with AGM.
1. over charge them and they will gas. There is no way to replace the electrolyte so the battery life span and capacity will both be adversely affected.
2. charging profile varies by maker and needs to be followed "to the letter" for best longevity.
3. if left partial charged they will sulphate and there is no method to easily reverse this process--without "violating" #1 above.
4. equalization is possible on some AGM's, and is not recommended on others, but it does take much greater care to do the procedure.
5. life span is no longer than flooded cells but cost is considerably more.
If I had pockets deep enough for AGM I'd go for six two volt cells.
Advantages have already been covered by others posters in the thread.
