I don't have an answer for you, but I did notice the same thing. I have been charging my deep cycles on standard. I am a little disappointed that it does not offer a separate deep cycle charge as this is my main reason for a new charger.

I also noted that deep cycle was left off these units , I have found that using the standard position on deep cycle will go to desulfate mode on deep cycle when determined by the computer. since the computer is evaluating the connected battery as it is charged I just assumed the company decided it was not necessary to have another position. if this is the case they should have included a note with these units.

You can use the battery, but it may not be a deep cycle. If the battery is for starting a gas operated mower it is not. If you are going to have a load that discharges the battery to low levels, it is better to have a deep cycle. I use an old car battery to run led lighting in my storage shed at night, but the battery never gets discharged very much, and to keep my deep cycle batteries for my camp trailer charged during the winter.

Section 2.8 of the manual says "Use the charger for charging only 6 and 12V LEAD-ACID, GEL and AGM-type rechargeable batteries with recommended rated capacities of 12Ah (6V) and 5-33Ah (12V). " My first attempt at this was a ProSeries PSC-15A-OB which, while a nice little charger, was NOT specified for use with AGM/gel. So I am now replacing with the SE-1-12S-CA. Oh, yeah, and a replacement battery too :-( You should call Schumacher if you have doubts; 800-621-5485 M-F 7-5 CDT.

It is not recommended to daisy chain deep cycle batteries when charging. It is my understanding that if one of the batteries fails it will draw down the others.

Optima and nearly all mfr's. of AGM batteries like these recommend a three stage, digital, charger. Stage 1 is a bulk delivery, at peak voltage, Stage 2 is a tapering charge; still at higher voltage but not continuous delivery, and Stage 3 is more of a maintenance mode where the charger only delivers capacity to the battery if it needs it, while maintaining the standing voltage at around 13.5VDC. I have my pair connected to a Digital MinnKota 210C(two 5A banks), and I use a Schumacher 15A single bank ship and shore marine model charger I purchased on the web as a backup. Both work exceptionally well with the Optima's, do not overcharge them, and keep the standing voltage where it needs to be.

I have a NOCO Genius 4 bank on board charger Nelson, and its the best charging system I've ever used. I use 2 conventional deep cycle 31 group batteries and 2 Optima batteries for 2- 24volts trolling motors. I called the company and spoke to a guy from his car while on the way home for Memorial day weekend. I found them to be more than helpfull and very knowledgeable. The cables are 6' long and you probably could extend them but I'd call NOCO and ask what gauge wire etc., affect the communication between battery and smart charger. I leave mine on 24-7 and have ZERO problems. It will be worth it even if you have to make a couple of calls to get the proper tech info.

Not recommended for deep cycle batteries. See Amazon website about this Maintain up to four 12 Volt standard, starting batteries (of similar type - in parallel). Amperage is divided evenly among connected batteries. (NOT recommended for deep cycle batteries)

My best answer is to check with the battery mfr. with the specs of the Battery Minder. I have another one for 2 - Lifeline 27T 100 AH AGMs in my camper and Lifeline had no objection. AGM batteries don't have need to destratify (my word...I forget the proper term) the acid, so there might be cheaper units without that feature designed for AGMs. Incidentally, my Vette will be 10 yrs. old in a few weeks..original battery.

If the generator has clean output I see no reason that the BatteryMinder AGM could fail to charge a big AGM battery. A cleaner solution might be to charge the bank direct from the solar cells, as long as the solar array doesn't have enough power to overcharge the AGM bank.

Do not wire it straight to the panel as it will over charge your battery in nothing flat. The panel came with a charge controller than it very easy to wire into the system. You wire your load up to 10 amps through the charge controller. If you are going to pull more amperage than 10 amps then hard wire that load to the battery. As far as charging the "low" battery there is a formula to determine the charge time but there are several variables you need to know to figure that out. It has no problems meeting our electrical needs on board a 20 foot sailboat with one deep cycle battery on board but our total load is less than 4 amps if everything was on at once. We have been just totally pleased with the panel and controller as they meet our needs perfectly.

Not sure as AGM is a brand I have tested deep cycle batteries with mine and had results as expected

No difference from other deep cycle batteries. The Optima batteries I have charge normally with both my on-board and portable chargers. I am on year 3 and have had zero issues.

Hello;In response to your question. Yes, the charger will work quite well for the Deep cycle battery. I use it on my Marine trolling batteries that draw down to nothing all the time. It works great!Jim

According to Lifeline the maker of my AGM batteries either the gel or sealed setting will give the right voltage. One thing you might need to know is if the batteries are discharged say down to 50 or 60% you need to bulk charge with enough amps (most say at least 10%of the battery bank's capacity), so a 300 amp system would need at least 30 amps as a minimum and more would be better in order to assure a full charge is achieved. You may want to check with your battery manufacture to get the exact specs to charge with so you can get the longest life from your batteries. I just use the 180 watts of solar panel to keep my already charged batteries at full charge.Have a great dayGary According to Lifeline the maker of my AGM batteries either the gel or sealed setting will give the right voltage.

You need a charger that has a setting for AGM batteries. My charger has settings for 3 types of batteries, standard flooded, AGM and gel. Optima recommends a 10 amp charger.

Deep cycle marine battery is best. To deal with the alarm you need to attach the alarm rod to the hot wire of your battery . I did it by way of the old post battery connection or your alarm will stay on . A marine battery generally has 2 connections for - and 2 for + that way you can connect an additional old post connector .

You will need deep cycle or Marine batteries for trolling motors. Unlike Car batteries, deep cycle batteries are designed to be discharged upto 80+% before recharging where as Car (starter) batteries have more cranking amps.
