will it test agm batteries

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

Michael, yes you can test button cell batteries! It is a great caddy, it has two ports A,B and C to test batteries, the cell batteries go in port A to be tested. Very simple! I recommend this product, definitely a 5 star rating. Thanks for asking. Lori

Absolutely, I test mine a couple times a year. This tester works best when connected to the battery's post.

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.

Yes I suggest you try a side by side test to make sure. You can contact their website with questions. I believe they make a meter also.

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.

Absolutely! Matter of fact this multi-tester is so powerful, handy and easy to use, and with auto range feature; for instant, if you want to test your battery, just slide the switch to volt and read voltage instantly. This one is always in my pocket, every time when I want to test something quick, am always grab this one instead of my other big and expensive ones. My son always wants to borrow this little one for his robot project. Trust me, you will love it.

It can not test any battery well. There are other testers better then this. There is an inexpensive tester out there. I do not have the model number. It is black with a red slide to make contact with the terminals of the battery. It works great.

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 would not use this charger on a AGM or gel batteries. It has a voltage ramp-up (15-16 volts) periodically to reduce accumulation of sulfites on plates which is not good for these types of batteries.

yes, but the batteries must be the same type - traditional lead-acid, AGM, gel

Should be able to test 6 volt battery one at a time, not all connected together.

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

It can, but over time there will be problems. The AGM battery requires a different charging current and voltage, and temperature sensing. Check out the model, 2012 AGM which is an AGM only or the 12248 which is the Mac daddy and switchable for any type of battery.

Yes. 5watts isn't a whole lot if amperage. But for an agm battery the lower the amps the better.

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.
