What is the lifespan on this backup? I certainly would not want to have to replace it every year.

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 replace the battery itself every time I replace my vehicle battery. About 6 years. They still seem to have enough power to sound the alarm but I change them anyway.

i have not yet used this backup battery since installation. but im sure it should last more than a year unless your car is consistently being ran out of battery and forcing your alarm to use its backup battery.

We've had the viper alarm installed now for about two going on three years. It was installed with the tilt sensor and back up battery and we haven't had to replace it. I'm fairly certain it's used if not entirely at least in part so that just in case a smarty pants car thief comes along and cut the cables to your car battery so the alarm doesn't go off, so he can steal it quietly well the back up battery kicks in and allows the alarm to still sound. Hope this helps

I don't know why someone would say that. I have found them to be the most reliable drives I have ever owned. In fact, I can honestly say that I have never had to replace a Western Digital RE drive because of a failure. We have replaced some that were small enough to be obsolete, but in my recollection have never replaced one for any other reason in 9 years of business. Of course, your mileage may vary. We do make sure to keep them cool.

I've never had to replace it and use it constantly (1+ year I think). It's one of the few things that I don't have to recharge nightly! ;-)

It's lasted for over a year for me w/o problems. I can't speak to the warranty policy though.

I think it is one year - check the LaCie web site. I have 4 of these drives, one over three years old and all have been reliable.

I have had mine close to a year a year and haven't noticed any major issues. I will use mine for an hour to offload and then turn off. No shortage of battery had been noticed. If I had approached and exceeded the year mark, I supposed I would break the seal and seek out a a replacement charging device. My use is to basically offload 64GB or so of photo data and the to repeat the task again, at which time I would put the next 64GB on the Nexto to await being offloaded with the first batch to my PCs external drive at home. It's not excessive use, but it is busy work across several hours in an evening. I have had mine close to a year a year and haven't noticed any major issues.

Why would you want to use archival media meant to last hundreds of years to backup an OS? If you want to do this backing it up to a backup hdd or standard DVD or DB media is sufficient. Do you think you'll going to want to restore an OS you had installed over 20 years later? Probably be lucky to even find hardware you could install it on. I have standard media that has lasted over 10 years when kept in cool, dry, dark places. Which only means in a dwelling that's not hot and out of the light, especially sunlight. You'll get more than enough life from standard discs or a backup hdd for that. These discs are meant for storing irreplaceable data like personal photos and movies.

I had one last about 3 years and I'd say it had at most 40 hours on it. I have others that are still working, but at these prices, there should be absolutely no failures at all - no excuses!

I've had it for more than a year now, first used as a backup to the principle computer, now as backup to the secondary. No problems, works like a charm.

2 years max. If you leave it on all the time or travel with it, probably just over a year. It's not clear to me your exact setup - if this is a backup of a laptop or a desktop and if this is a disk that stays in one place or travels with you. Sadly, of 2 different brands of disks I have purchased in the last 3 years, most have them have failed around the 1 year mark. (I had a pair of Iomega disks fail within a week of each other at the 1 year mark, a WD disk I bought 6 months ago just failed) My general backup strategy is 2 identical disks (currently 1TB) that stay in my home office where I store pictures, music, documents, etc.. 1 disk is a backup of the other. Anything important is backed up to the 2 disks that stay at home. I use my WD 320 to bring copies of files and music/films along with me on trips. Keep in mind that if you are using your WD 320 as a backup of your laptop and take it on a trip and your bag gets stolen or the disk gets dropped and breaks, you are without a backup.

I have had it for almost a year and have not replaced it yet....if you keep it clean it lasts a long time depending upon how much its used.

Comes with 1 year warranty, Plug and play that is all you do. I have all C: on it plus my laptop and a second CPU. I still have lots of room on it. Great tool for backup.

I've had mine running non-stop for 6 months. No issues. I use it at work as a back up machine, never turn it off.

Yes, mainly it gives you enough time to properly shut down your system. So, it helps if you are there to do that. It also provides power-surge and power-spike protection which is critical to computer circuitry. Good safety-net when backing up large quantities of data. Shelf-life is 3 - 5 years (as stated elsewhere).

I don't expect to ever have to worry about the battery. These type of batteries last through thousands of charge cycles so if it fails in 10 years I will just buy a new one.

I really don't know, but I've had mine for at least a year, and I'm still using it, with no issues.

I believe it's a year, but I haven't had any issues in the last 3 years. I use it for everything.
