how long do hey last? do you have to recharge them or something? weve had ours for about 4 yrs now and noticed last year it wasnt working very well.

I am not sure how long they work maybe there was a surge in power. That caused it to not work so well anymore. might be helpful to put it on a surge the next time you get one.

I have had mine for about 1 year now. It is still working good. It does not have to be charged. I works off 110 volt.

They usually last 2 to 3 years and no u just plug it into the wall and it will start doing its job. That's how mine was also soo I got this one to replace it.

If the red light fails to cycle on - the device need replacing. My first set lasted four (4) years. I am on the third year of my second set. Make sure you switch outlet locations from time to time. Plus keep one on each level of the house.

If the lights blink red and green, its OKKeep some mice poison near your waste bucket. I just bought another one. They are inexpensive and last.

We have been using ours since at least June of last year & the battery has not died yet. So they last a long time.

Following the other answer: if the unit is not new, then, like rechargeable batteries, they eventually die. The power cord should be changed out to see if it's the problem.

Got mine in April and one side stopped working this week -- I've only had them for 4 months. Customer service has yet to respond. I'm not impressed.

Mine have lasted for over 2 years and still work. After they get older than that they do not last as long and get hard in the package. I always have some left year to year because I cannot always find them when I need them.

We've had ours for quite a while now and they haven't. Maybe the little cap on them are stripped and you need new ones.

Check and make they are switched to the on position. There is a button located on the back. Also, make sure they are fully charged before using. I charged mine 2 whole days in full sunlight. When charging make sure the switch is in the on position.Turn them off when it gets dark do this for 2 days. I have 2 sets I did this with both sets and they are working fine.

I have only had mine for a few months, ive had no issues with them holding a charge. When we were out of power for three days this summer, it was on and working all night and charged all day with regular daylight and was ready to go for the next evening. I just bought four more so we will have enough for the house.

We've had ours since Jan of this year & still have a Charge.. It helps if you keep them in a sunny location.. Charges my I-Phone & I-Pod fast!!

I bought them too. The batteries are probably dead. A similar thing happened to me. Mine lasted a couple of weeks with occasional use. Because they are "wireless", the system is always active even though the lights aren't on, looking for a signal to come on. Had I known of the short battery life BEFORE I purchased them, I wouldn't have bought them. Good luck to you.

I've used mine for several hours. I havent timed it but I've been very happy with my purchase. They will also provide a light beep to let you know before they die to plug them in.

I've had mine since May 2014 and they are still burning every evening. They are beginning to be less bright and I will change batteries soon. I can say mine have lasted six months until a battery change. Happy!

I use Sanyo rechargeable batteries that are superior to all others so last longer. Deoends on your batteries.

You need to recharge them until the little green light on the charger goes out. If you use them constantly (easy to do with a trimmer) they only seem to run a short time--20 minutes or so. I haven't tested my theory, but it seems that if I give them frequent, short breaks they seem to perform longer. (I use them in trimmer, chain saws, and drill.) Of course, if they're old they may just be worn out.

I'm having the same problem- they were working so well then yesterday off and on static and today it just turned off. New batteries didn't help either.

Beats me - that's the one problem with this device, I use it starting in about April through maybe the middle of July and then the batteries are dead. I'm not planning to tackle the problem again until spring, but it's just a bunch of batteries bound together, and I'm pretty sure with a little effort, I can figure out how to "make" one and use rechargeables or something so it will last longer. They used to carry these batteries on line and even through some seller on Amazon, but my guess is there were so many complaints about the product, people stopped carrying it - I know the place I bought it stopped carrying it and the batteries a long time ago. Hope this helps. Beats me - that's the one problem with this device, I use it starting in about April through maybe the middle of July and then the batteries are dead.
