How will I know when the batteries need to be replaced?

the key sensor started to beep on its own. It was like 3 or 4 beeps in a row.

I don't believe there is a way to tell until the transmitter and/or receivers stop working. The batteries should last a long time though. We have devices that use the same battery and they lasted at least two years, in most cases more than that long. Hope this helps.

Batteries are built in and rechargable.If they go bad you can replace them.

When the batteries run down, the alarm will go off continuously to let you know the batteries need to be replaced.

I have not had to change the battery yet. If you have a Batteries Plus in your area, I would suggest you take it there just to get their advice. That is what I will do.

We haven't had to replace any batteries, but I would assume these are button-type batteries and would possibly be available a major retailers (Wal-Mart) or certainly at a battery specialty store such as Batteries Plus. Suggest Amazon is probably the best bet of the other responses

Call the manufacturer. They can replace whatever you need. They should have batteries you can buy as well.

Hi Matthew. I see where you are going with this. I don't see an actual date on the battery itself. This info may be part of a serial number or another code. I am finding that the replacement battery is not holding a full charge the way I think it should. My opinion is that replacing the battery is simply a temporary solution. Every once in a while I get a message that the battery has less than 5-minutes backup left. This is not right! When I am faced with having to replace it again, I would very likely buy the whole assembly new. Hope this helps.

last time i changed the batteries was probably November or December last year at the latest. It's now June and the low battery light is constantly flashing all day so I need new D batteries.

I use Duracell batteries, but I do not use it in the same environment as you. I guess would check every 30 days or so. I would worry more about the electricity going out.

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

Batteries could be already charged or they are old and no longer holding a charge.

Take the old battery out and examine it. They are marked so identifying the replacement is easily accomplished.

We have had six of these units in our home for over a year. We replaced all batteries after approximately one year. One unit is outside in the cold and heat and it's batteries lasted a year. The unit will give a little chime note every three or four minutes when the batteries need to be replaced.

Screwed in plate on the bottom indicates that it takes AAA batteries. So I assume they can be replaced.
