Can this be used to charge an AGM battery?

Your question was not stupid, in spite of what the other person said. Many people do not understand the subtle differentiation between the different models, and if you're planning on charging an AGM battery these differences are important. The Battery Tender (non-Plus version) and the Battery Tender Plus are different chargers which behave differently. If you have an AGM battery, you want to use the Plus version, not the regular Battery Tender. Both the regular Battery Tender and the Battery Tender Plus have an absorption charge mode, but the maximum charge voltage is different for the non-Plus vs. the Plus version. This is because the AGM battery requires a higher voltage than the Battery tenders designed for conventional wet-cell lead-acid batteries were designed to deliver. The Plus version, which came after the regular version, uses a higher voltage that is required by the AGM type of battery. The lower voltage of the non-plus version will partially charge the AGM battery and go into maintenance mode prematurely. It will not fully charge an AGM battery so it will not do as good a job. The Plus version also has a timer to hold the absorption voltage longer than the non-Plus version. These specific changes in the Plus model were made to accommodate the charging requirements of Absorbed Glass Mat (AGM) style lead acid batteries. Although a Battery Tender (non-Plus) will "charge" an AGM battery most of the way, it doesn't fully charge the battery as well as the Plus version. For an AGM battery you want the Plus variant, for a non-AGM battery you want the non-Plus variant.

Read the product description before wasting time with stupid questions. Yes.

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 day Gary

I wouldn't think so, unless the solar system was meant to charge agm battery's. Hope this helps!

It probably does, but keep in mind that different batteries require different floating voltage ("maintenance mode" in other words). This charger has no voltage adjustments. For an expensive AGM battery you will want a better charger, the one that would allow voltage regulation, and also has a temperature compensation.

I have used these chargers on agm batteries with years of success six volt batteries as well just make sure use a surge protector and check them because sometimes you have to disconnect and reconnect to reboot

I've read where the agm batt can be charged by this charger when connected in parallel with another conventional battery. I also know that there are agm battery chargers available. I suggest that you look up the charging of the agm on youtube. Someone has probably already solved this type of problem. Cheers.

Well, it has micro-USB output. So I suppose so...But you need to be careful, it has a pretty big current! It is intended for a larger capacity batteries, like external batter bank.I use it for that.It says 2.1 Amps of current!And you device needs to support that charge current of course.

This charger is designed for AGM batteries. Works very well with the agm battery in my Harley, and the diehard in my truck.

Yes you can. AGM batteries don't contain any free roaming fluids like a lead acid battery and they have minimal venting so you can use them inside. If your going to use this battery enclosed make sure you have at least some venting to avoid the possible build up of explosive hydrogen gas. They are also military spec so they hold up to the elements very well. After 2 years of 90° Summers and -10° Winters outside they still look and funfunction like new.!

Yes it is. In fact no matter what type of vehicle even if like me you have upgraded to multiple AGM batteries this charger will work for you. It is simple to use (one button operation) and the microprocessor inside the charger ensures you don't overcharge your battery(s) even if its hooked up for months at a time.

Need to have a smart charger to charge AGM battery. Charger will shut off when battery is charged. Need to charge or get battery maintainer so battery will last long time

I do not think you should. There are specifics that you need to watch while charging AGM Batteries. You really should have a charger with a voltage meter so you can make sure you do not over charge and damage the 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.

Yes, I bought them for my UPS systems protecting computers, high buck TV's etc. The last units I bought are of absorbed glass mat (AGM) design. This is the best available generally and charging isn't as touchy as the paste designs. Charging using wet cell parameters (like most auto batteries) works fine although there are AGM specific chargers. My experience with AGM is they are tough, reliable and a big improvement.

I curently have an AGM battery in my car and it works amazing. it is mounted on my garage wall and I plug it in to the 12v port of the car. Great for a car that is parked alot of the time or driven daily.

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.

Yes there are chargers for it I got a fully automatic 1.5 amp charger at my local auto parts store for under $30. Just make sure that it can charge AGM batteries
