What are the pros and cons for using AGM batteries or flooded cell batteries?

AGM no maintenance no spill, Flooded lower price.

I have AGM in 5 vehicles and as house bats in the RV. Place them and forget.

Cost is big advantage to flooded. Easy maintenance is AGM strong suit. Also AGMs charge quicker but not enough to make it a game changer. If using in a solar application I would go with AGM.

I just replaced two flooded cell 6 volt house batteries with AGM batteries. $179 each at Sam's Club.

I had to check the flooded cell for water every month for 14 years.

The AGM batteries were twice the price. I don't care! Tired of checking and adding water.

Which Sam's club did you use? The one near me doesn't seem to carry them

twinboat post showed the AGM which I purchased.

I bought mine at the Fresno California Sam's club.

When doing the decision process between Wet & AGM's, understand that different batteries have different characteristics. How you use a battery in your RV'ing style, can make some characteristics more important to you.

For those who boon dock frequently, AGM's (As mentioned.) do charge faster. Drilling down to a specific brand of AGM, that faster charging can be significant.
Lifeline's (Perhaps others.) is one AGM that can handle a much higher charging AMP rate - thus reducing charging time.

"Due to the low impedance design, Lifeline® batteries can tolerate in-rush current levels as high as 5C (500A for a 100Ah battery)."

For larger battery banks, the 5C rate can be significant.

Why important? Well a good example happened to us this year at Lost Dutchman's Arizona State Park. They've reduced Generator hours to 2 hours in the AM and 2hrs in the PM. Total 4 hours. For those who have both large size battery banks, and higher consumption of AH's overnight. Four hours can be way less then need to replenish the AH's consumed. Some chargers do not have the capability to crank out too high of an AH's, so they must be able to charge longer to put in more AH's.

Having a battery that is capable of handling a higher AH charge, and charging sources that can deliver these higher AH's - become beneficial in areas where generator hours are limited.

We have a MS2812 which can Bulk charge at over a 100 AH's. We also have a MidNite Classic 150, fed by 1200W of solar, that can Bulk at over 90 AH's (Though in our set up, mid 70's AH's is what we usually see with peek sun conditions.). In addition to these, we also have a stand alone charger, that can also deliver Bulk charges of over 100AH's. (And when in use, we do connect the negative to a busbar to feed thru the shunt.).

We have these multi charging sources for while off grid, to cover for times say when multiple days of clouds and rain are involved, and solar output is greatly reduced.

Yes AGM's, specifically some brands of batteries, do charge faster. And that can for those who boon dock and are in limited generator hours usage areas - can make a big differences. (That two week stay at Lost Dutchman, was one where we had multiple days of clouds with rain/snow at times. Two or three of our neighbors, had to go out of the park every 2-4 days (Dependent on battery and AH usage.), so they could bring their batteries back up to 100% SOC. Two of them left twice in the AM, went to the near by Elk's, and then ran their generators until they reached float mode before returning.) With our external charger, plugged into a 20A in the coach, powered by the generator, augmenting the MS2812 - we were able to get back to 100% SOC every third day. (Not our first visit, as we did not have the external charger at that time, so we too would run out of the park every third day, to ready 100% SOC!).

And of course, a classic example where the Lithium battery types are a benefit. Much faster charging then Wet or AGM, and do not need to return to full charge!

Best to all,
Smitty

Flooded over time will give you serious corrosion issues with cables and the compartment , all which requires time

Faster charging, slower discharge, and a lot less likely to freeze

Life should be longer as well

Going to Trojan T-105 AGM has been a great upgrade and the only one necessary in my coach

Apparently AGM availability at Sams is very hit or miss - not available at any of the ones in Northern VA. Bought 2 6v 230ah flooded from Batteries+ instead

Sam's Club is certainly hit and miss on AGM's. Several problems apparently with the batteries.

I went with Trojan T-105 AGM and after 6 months they have been perfect and hold charge very well in all situations and recharge much faster than the flooded

I am never going back to flooded due to the corrosion issues with the cables and compartment, but I do use mine heavily with the Microwave and so on
