If the load side is connected to a deep cycle battery, it looks like it will show current battery voltage. How does it determine the wattage?

It actually depends on how you are using the meter. The meter is only one way, which means that if you are using a 'source' to charge your marine battery, then that source is gone and you need the battery to feed the source, you will blow the meter. Technically the battery is the source and whatever you have connected to the battery that takes the battery power is the load. Before you connect and use the meter, explain how you are using it and what information you are looking for.

watts is just amps x volts so it depends on how many amps you are drawing from the battery

The 100% really means nothing when read from the meter. Battery capacity isn't measured like that. A full battery is 12.7V with no load attached, and no external charging applied. You drive the voltage above this to help reverse the chemical process, and get the sulfates detached from the plates by utilizing as much potential as possible.

You can see how much power your using...works as described. I use it to see how much power I will need and then I know how big a solar panel or energy generating bike I will use to go off the grid.

You can use the volt meter to measure the voltage across battery terminals. That will give you an indication whether the battery is dead or alive. However, strictly speaking it is not a battery tester, since it does not draw any load current from the battery.

I used a volt meter and it went into float of 14.2V and dropped to 13.2 and went back to 14.2 and again dropped to 13.2V. That seems to be the float cycle. It did charge the battery for awhile with a slow rise before it went into float. I was using a 30W Renogy mono solar panel. I have 2 of these and they both work as described. I would not leave them on once the battery is full, and it goes into float, for too long. Batteries can be overcharged. I hope this helps, I did a review on youtube with the 30 W panel, showing the float.

There's an source and a load. Connect the battery to the source, connect the load (probably speed controller) to the load just as if you were connecting it to the battery. That's it. No wiring diagram needed, these things are pretty standard. Make sure you don't swap the black and red wires.

sir, i am confused by your statement. i would verify the battery is being charged. since it is DC current a simple multimeter will provide this information.i purchased this battery for a back up security system. the system becomes active in the event of a power loss.

Like LFM says, put the "Watt's Up" between battery and load. As long as it has some current from the battery, the unit will stay on and keep a running tally of amp hours, max/min voltage, etc.

You may already know this, but the "DC" in the model number is an indicator that the battery is a "Deep Cycle" battery.

I wish I could answer that. I power mine with a deep cycle battery. I can say that it uses very little power to work and works very well. It is a really great value

You have to have your "load" connected first, otherwise the amps will remain at zero. By load I mean whatever it is you're trying to power. First connect your load, then turn the voltage all the way up, turn the amps all the way down, and turn on the power switch. Then slowly turn up the amps, then slowly turn down the volts to desired volt settings. Again, you have to have connected whatever it is you're trying to power to power first. I know, it doesn't make sense, but that's how it works. It threw me for a loop when I first got mine too.

If you are interested in seeing the Amp hours being delivered by your battery, the "Watt's Up" would be wired up in line. This means the black and red leads from your battery would be connected to the respective black and red leads on the "source" side of the meter, then the black and red wires that are hooked up to your battery today, will be connected to the respective black and red wire on the "output" side of the "Watt's up" meter. The Watt's up meter has about 12 gauge wire and can handle only about 30 amps before it would melt down so plan accordingly. Watts=Volts X Amps. If further info is needed, the Watt's Up meter has several instructional videos on Youtube.

The "load" connection is for the purpose of connecting a "Load" of some kind (perhaps a light that you turn on at night or other such) where the controller will allow your "Load" to drain the battery down to ~11V, but then it "shuts off" the load to not drain the battery to the point that it's hard to get it to recharge. So that should help preserve the life of the battery, but that "load" can not exceed the 7 amp controller ability.

I found the voltage approximate with 0.25 to 0.5V. Generally the measured voltage would depend on the load. A high current load will likely drop the measured voltage.

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...

Press Menu until you get to Volts, then press Up or Down keys to find Watts.That is what the manual says.

You just need to click the button near the indicated lights. It will show you remain battery level, 4 bars means full power. If 1 bar left, you have to charge it .
