Can it monitor the car battery too? Is there an audible allarm in low presure case or color change?

Yes, it monitors the car battery and the pressure and temperature of the tires. There is an audible and visual alarm when there is a rapid change in either the tire pressure or the car battery status. Thanks for asking. Safe driving!

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 you turn it on it will flash a light twice indicating the battery level. Just look to make sure the light is green. It will change to yellow or red (I can't remember which) when the battery runs low. My battery lasted a very long time, 17 months before I had to change it.

To my knowledge all these tools do is wake up the sensors. They will read id's battery life etc. but you still need the car computer to read (or be told to read) the sensor. Most cars I've worked on automatically read the new sensor. Nissan is the only one I have consistently had to enter the car computer to recognize. Promised updates seem to be a problem with this tool.

It has a battery indicator on the screen along with a cell signal indicator

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery

It does have a very small light indicator that shows when it is recording (green) and when it needs to be charged (orange). It doesnt make any noise.

problems yet..only will go off if someone cuts the cables to your battery..you can get a volt tester to check if uncertain..

I am not sure but could test it for you. Are you able to have it installed so it's connected to the battery of the car? If you want to me to email you the results I can.

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

To be honest the battery life seems really good and I have yet to get to the point where the battery has gotten low enough to get some kindof warning . There is a very small led light which is either red or blue I'd imagine that is probably the indicator light to let a person knowwhen the battery is low. I would have to check the manual to be positive though. I hope this info still helps.

Yes, the charger enters what it calls a plulse mode that monitors the batteries voltage and keeps it at optimum charge. I have mine on my car all winter and with the indicator lights on the charger you can see what or where it is in the charge or maintain cycle.

there is no way this could possibly drain your battery & if something does drain your battery it's not this & something else one would need to check in there car's electrical.

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.

No, there is an indicator but it won't tell the battery status. BTW, the battery is pretty strong and long lasting. it will be good match to Surface Pro 3.

There is no battery indicator nor does it tell you the battery level.......

Yes you can, and also record the voltage that the battery contains. Although this unit is meant to do much more than that, and there are other less expensive multi-meters or battery testers that can give that type of information.
