Does it test AGM batteries?

Yes it does, both flat plate Absorbed Glass Mat and spiral wound AGM design.

Yes it can. From the manual "The testers are compatible with a wide range of battery types,including Conventional, Maintenance Free, AGM, Gel Cell, Marine and Deep Cyclebatteries."

no, it would not put any kind of a load on the battery to give you an accurate test

Sorry, but this tester is for "bare" batteries rather than multi-cell battery packs. It's the best tester there is for what it does, but isn't designed to test dedicated camera battery packs and the like.

I use a Genius G3500 Charger/Maintainer. It has a special charging mode for AGM batteries. Just make sure to use a charging system that is smart enough to charge and manage AGM batteries. By the way, the Vmaxtanks MR107 12v 85AH battery is wonderful. I highly recommend this product.

Yes you can, and also record the voltage that the battery contains. Although this unit is meant to do much more than that, and there are other less expensive multi-meters or battery testers that can give that type of information.

I don't know for sure, but i am almost sure it doesn't. This range of current is very small and if it does measure it, it will not be accurate. I will recommend a multitester for this range of current, not a Clamp Tester. you cannot measure current with the test leads con this model, only with the clamps, and it will not be accurate

Yes it does detect bad batteries by showing a blinking light for the battery or batteries.

Yes it does. There are two chrome buttons (contacts) on the left front for testing 9volt batteries. You also must set the dial to 9V. Hope that helps.

No, but make sure your charger charges this AGM battery with the proper voltage. AGM batteries require voltage of slightly over 14 volts

No it does not. Just give status of each battery as its going thru the charge cycle. It probably works this way because you can charge different capacity batteries like AA and AAA in the same charge cycle.

Yes it does. It shows the voltage from the panel(s) and also the voltage and amperage going to the batteries. As well as the State of Charge of the batteries. It's well worth the money.

Yes this tester can apply a load for testing and evaluating the condition of Sealed Lead Acid batteries

Hi R.W., this tester will certainly tell you if smaller batteries are in good shape but it is kind of over kill as it works by resistance testing. Kind of like plugging a toaster onto your battery. It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward. I use it for 4 and 8 D size batteries for starting large diesel engines. I would suggest a lighter amp load tester for what you are doing. Something around a 50 amp range. Hope this helps.

I believe it does according to the manufacturer's manual. I only use it for 18360 batteries.

You get the best indication of battery condition under load. All this tester does is provide a load and measure voltage. I expect it wold work fine for your deep cycle batteries.

There's a round space that is labeled 3v and another labeled 1.5 v. I have no clue if either would test A23 batteries.

Same problem with aircraft batteries. I tried setting it at a low CCA battery setting to see what would happen and got a reading. I have no way to know if that result is accurate. The thing is designed around inputting the CCA to do the test, so I guess it might not be the answer for you. You might want to consider a carbon pile style tester.
