How do I know when it is time to replace the battery? The unit tell you when the battery is running low?

The unit will start chirping when something is wrong including when the battery needs to be replaced. The green Ready light will be off and the blue i-button will be flashing. Press the blue i-button, and it will tell you what to do next such as whether the battery needs to be replaced.

The unit will beep like a smoke detector that has a low battery. Also the the expiration date is clearly printed in plain sight on the back. Same with the pads.

The unit starts to beep rather loudly and doesn't stop till you replace the battery...if I remember correctly.

Yes, the unit will alarm and give you a message when it is time to replace the battery or pads.

No. There isn't any indication of low battery. However, it uses a nine volt and doesn't seem to draw much current. I've had mine in for months (on two of them) and they are still working without a problem. It's a great little burglar alarm for the price. For securities sake, you might want to replace them about every 6-9 months even if they are still working.

You can check the voltage. If you check it right after it's been running and then again after it's been sitting for some time it could show you a drop in the stored voltage, however this could indicate a constant drain on the battery unless you disconnect the negative terminal when doing the test. If you are trying to determine if the battery is weak, then you really need a load tester.

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.

I'm not sure, I've never had that message before. Maybe you have a faulty unit or your battery in it is low for some reason. You could open it and replace the battery or you could contact the seller and see if they know why it's doing that. I'm sure they'll replace it if you believe it's faulty.

Let the battery charge for awhile then take out the battery. There should be a small dark button on the battery itself. When pressed a number of lights will come on on indicating how much charge it has. If this lights do not appear I would return the battery for a new one.

When you replace the battery then a setup about measure units to be shown appear. You can force this by removing the battery and put it back.

Check that the battery is 1) good, and 2) installed in the correct direction. If it does not turn on automatically when these are correct, then the unit may be faulty.

If it is a new unit, try a different new battery (as the battery could be defective), followed by a different new unit.If it is an old unit, I would suspect it has failed (i.e. reached its lifetime, say over 5 years), and needs replacement.

Once it's set, you're good to go. I installed mine well over a year ago. After unplugging to go out on the lake, I just replug it in when I return and it "remembers" the setting. I haven't had to replace a battery in two years.

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,

If it no longer takes a charge, it is most likely the battery. You won't know for sure until you replace the battery.

I have had mine for several years, works great, probably time to get a new one. The battery level indicator seems to only appear when i have about a minute left, would really like a count down...minutes left or shots left.

When it pairs with your phone, there's a small battery indicator next to the Bluetooth symbol at the top of the screen. The speaker also tells you when it is very low.

My guess is that it is trying to tell you the battery is low. Try replacing it.

Why would one need a battery for something new? If it doesn't take a charge, the unit should be replaced under warranty.

The battery is low and it is about to go dead. Anyway that is what happens to mine. Hope that helps!
