does it test agm batteries

The mfg would be able to answer that. We used it for flooded lead acid, the results were of no value. 6 out of 10 times it would fail new batteries .

Yes it does. Like on the mbz batteries yes. We have tested em and the dealer has tested em same results less bs. Ya know. Pass or fail. Any questions call me I own a roadside assistance biz in orange county ca. 949-702-1420

I don't honestly know, but in theory it has the proper setting and the test leads can be positioned on any battery as long as the positive and negative sides are accessible so my guess is that it can. Hope this helps.

AGM and SLA (Sealed Lead Acid) batteries are the same thing.I hope this helps you with your purchase.

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.

The PD website doesn't indicate one way or the other. I wouldn't hesitate to use it with AGM batteries. AGM batteries are a waste of money for RVs unless you are doing serious off roading and need the vibration resistance or ability to mount at any angle. Otherwise a good quality deep cycle battery is a much better choice.

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 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.

No, it does not test watch batteries! There are other specific testers for watch batteries.

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.

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

This battery tester does test button batteries. It depends on which button battery your wrist watch uses whether or not it will test it.

If you're asking if you can recharge an AGM battery that has been fully discharged, the answer is yes, but most standard battery chargers won't work. Either need an AGM specific charger, or there are some tricks you can use to make standard chargers work.

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.

It is not a load tester. It does not place a load on the battery. It measures the reluctance of the battery and calculates the CCA.

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.

It will test #312 batteries, but it appears to be a "no load" test. I have tested hearing aid batteries that tested fine one day and didn't work the next. I have pretty much stop using this device.

This tester will not test car batteries it's designed for AA, AAA's, Button batteries, hobby batteries ,9 volt and watch batteries. For car batteries you need a tester that will put a load on it to test the capacityfor cold cranking. Hope this answers your question.
