I have both outside/inside units plugged in power all the time, but battery died after 4 months of usage. what can i do? is the battery replaceable?

The battery is replaceable, but only when the outside unit is powered properly will the rechargeable battery stay charged (It uses power through a USB converter from a 120/110 AC adapter). An AC unit that is properly wired and constantly plugged in, should never have a power failure. The internal rechargeable batteries are just for battery backup in the event of an AC power failure. Verify that the camera/buzzer unit has its two pronged connector in the back of the unit plugged securely into the proper location. This connection sometimes slips out if tugged on. I hope this is of some help. Dr. C.

I have not had this issue, but I do not leave mine plugged in. I would check to see if a power surge took out the unit, or a battery issue

I suggest that you buy another unit then use a two way-plug to power both units. Or, contact the mfg. to see if splicing one into the other won't damage your units.

Get a different model that only uses batteries. There an argument that a battery one is preferable since you will need to periodically check it, and one off of the house power you tend to ignore, and then it fails when house power is off, even though it ha a battery back-up which is died earlier. Regrettably that has happened to me.

The life of any battery is limited. I am keeping the unit plugged in for the time I have to used it.

I don't have a good answer to this. My only suggestions would be to a) leave it plugged in while using it (which doesn't even require the battery to be in it), b) email 3M to see about getting a free battery replacement, and/or c) buy a replacement battery. Hope this helps.

I have owned two of these units and I could never figure out how to replace the battery. It may be possible, if you are more technical than me. I found that the power cords go out, but you can buy very inexpensive new ones on Amazon.

there is a battery inside the unit that doesn't need to be replace, it is rechargeable, to recharge it just connect it to a USB port and that is it.

Mine used to work great while plugged in even with low battery, recently this isn't the case. I have it for more then 2 years and now the battery doesn't hold the charge long enough for a single use and the unit doesn't work solely on the AC power, i.e. with no battery and plugged in, it doesn't work now.

I have had a unit for quite a few years. I thought my battery had died and replacements were expensive. Started looking at just getting a new unit. Then I put the battery back in and it has worked fine for what has now been a couple more years. Don't know what happened, might have been a connection problem????

I would take the remote apart and see if a wire just came loose because they're too new to have the battery died on you like thatand if you do find out that the battery did die if you cheaper to replace the battery since you already have the park by any other replacement pieces other colors or the remote

Buying a battery might be a cheap fix. Make sure the charging unit is plugged in and it lights up when the unit is placed in the charger. If the unit is new, send it back.

I have yet to replace mine. And I've had teh unit for a number of years now. I suppose the battery life will depend how heavily it is used. Mine is moderately used.

The same thing happed to me. I replace the batter (which wasn't cheap) and it worked for about a week then died. Not sure that it can be replaced.

Dead battery? Get a jump! haha Seriously now.Are you sure its the battery? Does it work when its plugged in? As soon as you unplug,does it stop working? If that's the case,I'd take it in to a computer shop to get looked at.Is it still under warranty,& if that's the case,send it in.I haven't looked at my own manual,but can you change the battery yourself? I'd see if I could do it first myself,instead of paying omeone for something you might be able to do yourself.

Try the battery first, of course, but if that's not it, you should call customer service. One time they had me change a setting in the unit that plugs into the wall. I will say, though, that this is not a reliable product and doesn't last very long, especially if you are using it a place where it is subject to weather. I have two--one at the front door in a breezeway and one on a gate outside by the mailbox. The one in the covered area last a lot longer than the other.
