will this gauge the charge or battery life of a high AH deep cycle battery, like something with 200-400AH? Looking for a meter that can tell me how much life is left in the battery and how much power/charge? remains. Anyone know of other devices that...

Hello, Your question is very vague in the type of solar system that you have. A Charge Controller is usually used in a system that feeds batteries. Depending on the complexity of your system determines on the type of charge controller that you typically would have. This gauge will only tell you what one batteries current state is. The battery would have to removed from the system to get an accurate reading. The gauge check is very simple in its process to determine your battery state. What is the current voltage and hold long can it hold it for 10 seconds. Without more information, that is about as good of answer I can provide at the moment. I hope that it helps Thank you, Avel Ureno BatteriesInAFlash Tech

There's no battery gauge. I believe the button light turns red to give you a warning that it's low on battery. The button stays green when fully charge. The color scheme is on the directions.

That indicates battery is fulley charged and desulfated. It may take A while to finish the desulfating cycle but it is well worth the waiting, it will give your battery much added life.

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

On the display, the meter shows the battery, with the amount of charge left on it. But it does not give a precise number. You have to estimate it from the simple diagram.

Hi Grant! I don't have quantitative data, unfortunately, and I could find no numbers on the Web. We've found the life of these batteries (between charges) to be acceptable for our uses. We're not pros, so we don't go out for extended time periods and burn the batteries all the way down. We've not been caught short or in need of a charge by these items, under our use conditions. Sorry I don't have better info; all we can say is we've used them for a short while and noticed no operational difference from OEM units in our hands.

its not a load tester. it uses different system i think. i have a battery. it shows it needs recharge. but cca is ok... i dont understand is it working or can i trust its test...

Yes, that is what the meter does, to clarify it tells you the CCA that the battery is capable of in its present condition, it does not tell you what the CCA of the battery was capable of when manufactured. It also does not tell you battery capacity. Someone else said no, that is a wrong answer as stated

Not sure, but it could be that your batteries are not holding a sufficient charge to register as full on the meter. Try checking each of your batteries separately with a multi meter. Each of my (old weak batteries) show 7v dc each when fully charged, and 6v when depleted. On the meter this shows up as overcharged (or near the H in the white CHG area) when charged and halfway down the green area when discharged. Hope this helps.

I use this meter everyday, nothing new that a meter like this will drain the AA and AAA. Never seen it as a problem, get the cheap Fluke, it will keep the batterys for 2yrs even.

I might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

I didn't see the battery load test described with this meter, nor do I see you that function on the meter. Would like to have that as I understand that gives you a realistic reading how a battery performs under load, not just a voltage output.

Mark: This company markets internationally. I am in the US and have 60 hz. I would go the web site and check, but I think that there may be a switch on the unit for either. I have found this unit to be highly reliable. I have been using it for a year and my batteries have been maintained at 13.7 V to 13.9 V. I am using the old standard lead acid batteries on a sailboat and charge a bank of 3 of the deep cycle batteries. One bank shares one 10 amp feed and the battery I used as house battery has the other channel. It is important to install the battery charger with stand-offs about 1.5 inches from the bulk head to allow circulation of air for heat dissipation. This unit has been reliable and trouble free. It has been on line 24/7 now for over a year. Hope this helps. James D.

That is a great question. I really haven't noticed it being drained too much after no use. To be honest, I haven't really tested that too much. I think mine is dead right now. I would think it's like every other battery and it will lose some charge after no use. Just don't know how much.Regardless, it's a great device and I love it. It's saved me several times.

I will try my best to help you with your question. First the batteries need to be fully charged overnight. Next they should not be connected to any equipment in any way including ground. Next follow all the instructions for the testing procedure. When doing the test which is a very short time period as indicated in the instructions you will get the reading on the meter and it will change the longer you keep the load switch engaged, it will also get hot in the tester and smell also. This is normal as the tester is putting a 100 amp load on the battery and determines how long the battery can maintain its voltage. This is why you should not hold the load switch longer than the specified time. Use a watch to time the length of time that you keep the load switch pressed and keep an eye on the meter reading. If you have followed all the instructions to the letter and you still get a low reading I would take the new battery to a place like NAPA or Auto Zone and have it tested there. That way you will know if the tester is at fault. It is a pretty simple device and there is not much to go wrong with it. Just be careful handling the meter just after testing and hold it by the handle until it cools down. The other answers you received are spot on correct. " Slightly weak" does not give any of us the whole picture of the test being performed also it is highly unusual to find a new battery that is weak once it has been fully charged and put into service. Good luck. Harold

dont know but its very little.i hooked mine up to my deep cycle battery overnight with my digital meter also hooked up and didnt drop any volts, not even a tenth of a volt.

it can measure mA to see if you have a car battery drain.. I believe it can read mV as it goes several decimal places when evaluation AA and AAA batteries
