The box has 3 led lights by the power switch which indicate when full and low of power.its a great product.and the battery reallly does last a long time

I don't think the light color is a working estimation of whether the battery is charged or not. I believe mine is always green, I usually look at the light strength to monitor it when its charging.

found the manual,, it does show battery power ( page 58). I really like this fish finder..

I have an indicator, and it shows that the battery is going down. I haven't let it get to the point of running out of power.

Just open the cover plate look at the battery( + - ) indicators & slide the AA in.

It has a light to let you know when it's done charging. I usually left it plugged in overnight, but no amount of charging was ever enough to give me more than 10-15% battery power. I just pitched it and bought the PowerAdd 5200mAh. It was only $13, and it gives me 1+ full charge.

Sorry, haven't a clue. I've not even tried mine, just wanted something to test batteries before purchasing them unnecessarily.

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.

If I understand your question, you could look on the back or the bottom of the device where there is usually a label that lists how much power it uses. Also the transformer/power block that you plug in to charge the device will show how much power it draws. I hope this helps.

There is a battery indicator on the main screen when on. The light stays on when plugged in

No, it's not likely to tell you battery health. It's possible that by monitoring the charge amperage at different phases you could see one is problematic but that would not be conclusive. If you live withing range of an Apple store, simply make a Genius Bar appointment and ask them to diagnose your battery. They have an app that gives them access to your phone's diagnostics and will show them the battery health. They can tell you exactly how health the battery is and it's free.This will only tell you the rate at which your charger and cable is delivering power to the phone. Above 80% the phone reduces the charge rate but below 80% it should charge at a full 1Amp (5 watts.) No, it's not likely to tell you battery health.

Hook it up to the battery you want to test and select test. The tester will test the battery ans tell you if it is good or bad,

There is an indicator bar on the right side of the front screen. As the battery is used the bar decreases. Unplug the dock from power and check the indicator to see how much battery there is.

Mine is mounted inside the RV but I can't imagine that it is just by looking at it. Also, I regret buying it. It really doesn't tell you much important information. The better solution I've figured out is to buy a shunt. This would be the only way to accurately know the real amount of power that your batteries have left.

The same way you turn it on. There's a marked power button on the lower left of the case. Tap it to show how much charge remains in the backup battery. Hold it down to turn it on if the backup battery is currently off. Hold the button down while the backup battery is on, and it'll turn off.

It shows that the power is successfully connected. It goes out but never lets you know when fully charged. Sorry, I just let it go for a few hours.

There is a battery level indicator on the battery. You press a button and a series of green indicator lights show how much charge it has.
