Will this work on AGM batteries, I see the name plate says lead-acid only. I will use a charge controller on the battery bank if that helps.

I am not using it on AGM batteries, but they are just lead acid batteries in a more efficient configuration, so I wouldn't be afraid to use this battery charger on AGM batteries.

most newer chargers have a setting for the agm gel type batteries, you want to use no more than a 12 to 15 amp preferably a 2 amp charger, kind of like a deep cycle battery less amps for longer time.. But when my charger was on the agm/gel battery settings it was showing 12 to 15 amps most of the time.. Good luck if you get one.

vA=w(Volts)(amps)=watts. Regardless of AC or DC. And lead acid batteries work fine, just use a true deep cycle battery like a 6vdc "golf cart" type battery. These are much better than Marine deep cycle. Just make sure your input DC volts matches the units input parameters. The main issue is the battery charging. Lead acid has a different charging parameter than whatever is in this unit... sealed agm probably. Just bypass the charging circuit and add an appropriate charge controller. There are many good ones on the market.

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

I've seen this question before and found one particular answer/response very helpful- the charging system of the vehicle you are putting it in used to charge a lead acid battery did it not? I use a solar NOCO trickle charger on mine. NOCO Battery Life BLSOLAR5 5 Watt Solar Battery Charger and Maintainer

I don't know about different batteries, as all mine are AGM. It works perfectly for my needs.

On pg 13 of the English section of the manual it says "All types of lead-acid batteries (Wet, Maintenance Free, AGM and most GEL)." On the cover it says "For lead-acid batteries 14-150 Ah". It repeats that restriction in the IMPORTANT SAFETY INSTRUCTIONS and adds "do not use for any other purpose." In the PERSONAL PRECAUTIONS section, it says "Use charger for charging a LEAD-ACID battery only." If I were you I would check the CTEK website and look for a different charger, send them an inquiry, or call them. It appears to me the answer must be no. But I am no expert.

Yep they will work with AGM's, I don't have a boat, so I can't answer that part, but as far as the batteries go this is a great charger for them. I would say as long as the battery bank is in a dry area you should be good to go.

It will work. AGM batteries can be used in any orientation, that is one of their main advantages.

This unit will work on any 12V lead acid type battery no matyter what it is in/on. If you don't drive the car often just hook up the alligator clips. If you store it get the cord that will tie to the battery and run it out under the hood of car and simply unplug when you want to drive the car.

Yes, you could. But, the life of the battery would be reduced. Agm batteries have special charge requirements. And you would be mixing old and new batteries together. Battery performance can only run as good as the oldest one and would bring the life of the new down to match the older one. All batteries for best results should match type, size, and age. spend an extra $100 and get a good quality charger.

The unit can charge AGM type batteries, but I do not know if it can charge the yellowtop battery. I bought it to use with an AGM battery I expected to buy as a replacement for an aging car battery. When I received the Ctek MUS 4.3 charger, I used it to recondition the old battery. I will not need to get the AGM battery for a while.

The manual says it is suitable for all types of lead acid batteries from 15Ah through 300Ah. Check your battery capacity, if less than 15Ah, the manual would say no. Otherwise, no worries.

The quick and easy answer is, Yes, it should work for that, the only thing I haven't tested with it is how it will react to loss of source voltage. You'll just have to be sure to set up the output voltage limit to the proper value for the 36 volt battery (41.4V or so for lead acid). I would also set the current limit to a value that would not overload the solar cells in normal lighting conditions.

A couple of things to know about these type of batteries. One never let them sit for long periods of allowing them to discharge below 10.5 volts. They will not recover. I have a battery tender in my boat which regulates these batteries at full charge at all times. Second your charger should have a AGM setting. You can find what you need on optima's web site. http://www.optimabatteries.com

It would charge it, but not to quite full charge. It is not the ideal charger for an AGM. They require a little more voltage. This also is not a "smart" charger and can overcharge a regular battery if left on too long. If nothing else get an upgrade from this one.

You could, but it would not be good for the battery and might destroy it. As a rule you don't want to charge a lead acid battery with any higher current than it can produce. A fast charge up to the rated current of the battery can be done, but a lower rate of charge than the batteries maximum makes the battery last longer.
