i've got 2 12v and 6 8v deep cycle batteries on an electric boat and looking for a good tester. will this work , any suggestions ? thx.

Hello from "down under". I have tried to use them on 6V batteries and it won't work. I suspect that the "smarts" in the elcetronics have been set up to only test 12V batteries and nothing lower. Based on that, I suspect that you will the same issues with testing 8V batteries as well

I use this voltage and cranking amp tester on a Bass Tracker deep V-18 ft. boat with its batteries and also on our 3 vehicles' batteries. It works great. Big Wal

I've used this tester on both 12v and 6v batteries but I've never seen an 8v battery. This is the best tester I've ever used and is well worth the price.

It works on 12 volt batteries only. I have never seen an 8 volt secondary battery. You could test 6 volt batteries by connecting then in series.The tester will indicate that the battery needs charging if connected to a 6 volt battery.

Sorry, I don't know the answer. My boat has a dual battery 12 volt system. I routinely use the batteries (and run the engine) with the charger running.

I have three batteries on my boat each is connected through an 80 amp continuous solenoid. The set up works fine it keeps me from having to open the hatch to turn the batteries on and off each time. ALWAYS remember to turn off when not in use or leave the battery charger on otherwise they will run the batteries down. Hope this helps. Charles

Yes. Rechargeables are slightly lower voltage. Hence you need a true "battery tester". This is a batter tester. Not a voltage meter.

My battery tester works fine. Making sure the battery is laying on the flat metal area than pushing it against the metal wire-like strip should give you a read out. If no action, request a replacement.

I have only used it for my boat (12V marine battery) and it works fine. It works great for any 12V battery. I am not sure what kind of battery you use. I suggest you contact the manufacturer..they were very helpful to me.

I do not see any markings for testing a 3.7 Li-ion volt battery on the unit, perhaps you're exceeding the voltage limits of the unit or maybe that's too many Ah (AMPs) for the unit. I suspect that it's shutting down to protect its self? My ZTS tester has worked flawlessy since i've purchased it, over a year ago. As always, consult the manufacturer for the final answer on the product they have designed.

In my opinion, this tester is suitable for detecting good from dead batteries, and that's how I use it. For anything that is not full but has some life left in it, I would treat it as dead and in need of charge.

Maybe! I had to buy a transformer for home use. Not sure with DC of a boat battery. Good Luck.

It is 24 volt so you would need 2 deep cycle marine batteries. Any brand would is fine.

Any deep cycle battery will work fine. I use the same one as I use on my trolling motor and don't have any issues.

Dave I have a lowarance fish finder and I use this little battery all day without a major drop in its charge!! I use a couple of alligator clips like those used on a circuit tester, they do not get over heated and I do not use any type fuses. You can probably check the manuals on your equipment to see what size fuse, maybe a fuse say 10 amps should be just fine. I have charged and re-charged this little battery many times and still performs perfect. butch

If it is a deep cycle battery or a regular starting battery. I have one on my boat for the deep cycle battery and my dad has one on his boat for a regular battery. And it works GREAT

Yes it should work on all 6 and 12 volt batteries. Reading the voltage as well as being able to tell you if it can take a load. I'm satisfied with its' performance. Your deep cycle battery is still a 12 volt, being designed to handle a greater range of charged to discharged cycles. .

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.

M_ENGLE and DUSTY comments contradicts what Bob commented...I want to use this device for load testing and confirm the condition of any battery......who am i to be believe now, because am about to place order.

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 .
