I have been using them for 2 years. if you use them twice a day they will last 30 days. You than need to replace them. I don believe it is permanent, you will have to continue on a maintenance program I sometimes forget, but most of time I use them at least once a day I hope this helps by iluvmath65@yahoo.com

I don't know for sure how long they last. You may need to check with the manufacturer, but as long as they stay sealed in the packaging so that they don't dry out, they should last a long time.

They last for like a year. The expiration date is on the top it is show as "year-month"

They are designed to last approximately 30-45 days. However, I have seen customers that have gotten much more time out of them. An average usage time would be about 2 months.

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

I read somewhere that these are suppose to last for up to a year. Just make sure you keep them stored somewhere cool.

Celeste, I currently own 6 of them and they are close to being 6 years old. However, I really don't anticipate they will last forever, I have read several reviews of units lasting as long as 15 years. If mine give out today, it's a cheap investment, and they work...

Mine hasn't burnt out yet so I am not sure how long they last. Ours are not located in a spot where we use them every day either.

So far they have lasted about 6 months. As to buying locally, I haven't found any store that sells them.

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

I have not owned it long enough to determine this. They have lasted at least a month so far. Sorry...

I'm not sure entirely, but the computer will complain if they are too old (planned obsolescence). They have lasted for anywhere from 1.5 to 2.5 years has been my experience.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

During the warmer months, they've lasted 2 to 3 months. Winter time, I would check every 2 weeks depending how cold it gets.

It depends on how heavy the usage is on your system. They usually last about 3 to 4 months with our system.

I've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.
