Is there a light of some sort that tells when the battery runs low?

Hello this thing lasted me only about 2 months it just stopped making no sounds it has a light. That was totally no use for me. Sorry

No. My battery came nearly dead and I didn't see any light indicating a problem.

No, I don't think so but you can always check the flashlight once a week and then change the batteries when it starts being not as bright anymore.

No low battery indicator. If you cover the unit in your hand you can muffle the sound and remove the pin to test it once a week. I got this for my daughter and its cool to hook on a purse, jacket zipper or a belt loop. No fumbling to push a button, just pull and it goes pretty loud.

When the battery is low you will get an audible alert that says "battery low" when you switch it on or push the button down. The light will also be red/orange when turned on when the battery is low

My husband gave this answer: It has one light on it. Which doesnt tell you anything about the state of the battery unless its dead.

Has a power button on back that is lit up & will flash when battery is low. Charged mine about 2 weeks ago & have yet needed to recharge it. But has no battery level indicator.

The remote will indicate when it is low on battery by displaying a red battery icon on the little LCD screen on the remote. There is no way to know when this is going to happen, it just tells you it is low and then lasts about one more day then dies. Hope this helps answer your question.

No, chirping is the only alert to low battery status. Red light indicates either no DC connection or the detector is not properly connected to others in the chain. Green light indicates unit is performing as it should.

No . I have read that by holding the power button on other models a flashing light would represent remaining power . This does not seem to be the case with this light . I charge the battery after 3-4.5 hours of use so I don't know how it reacts to a low battery .

No low battery indicator, not sure how many hours for the 9 volt battery but I'm use the same one from about two months ago. There is a on light inside that let's you that the device is working.

Yes there is a battery level indicator, but I can say how accurate it is at monitoring the actual voltage. Lead Acid batteries do not like to be deeply discharged like Ni-Cads, so you must keep them charged regularly.

Yes it does detect bad batteries by showing a blinking light for the battery or batteries.

No. A light will blink when it gets low, but until that time, there is no indication.

The power light on the right side of the unit "should" indicate the battery status of the unit, not the battery being tested. So, here's a thought, try putting "fresh" batteries in the unit, then run your test again.

There is not a light. The initial battery I put in is still OK. I was concerned that the battery life would be short, but have been very pleased with it so far.

No, but there is a small LCD display that indicates battery status, caps lock, num lock and scroll lock when these are activated.

There is no indicator light. Battery lasts quite a long time and you can usually tell when it's slowing down, in enough time to finish the job, then recharge. I use mine on the lowest setting to shave my entire head in close (not quite 'shiney close--it's not meant for that) and on a couple occasions I've plugged it in to finish the job because I wasn't careful to listen close enough as it was winding down. But I'd take it on a 2 or 3 week vacation w/o the cord--it keeps a charge quite a while.
