I notice 2010.08.whatever, doesn't this make this very near the 5 years a battery lasts, even if sitting unused on a shelf?

I have noticed that if the battery is not used, it is good for the time stated. Of course, any use or over charging will void the life of the battery. Just make sure if the battery is NOT used it is as good as new.

Haven't heard anything about that before. Only know that the 3 purchased work in my phone. The original one that came in phone wouldn't hold a charge, had expanded and could spin.

depends on the batteries you use... I guess. but mine last for about half a year

I've had mine installed for just under 60 days and the battery life still boasts duration until 2020. That's with all "senses" in use. Assuming that's accurate information, that would be awesome.

My understanding is that manufacture's batteries last a year or more copies last a few months. Shop for the proprietary product

I have a battery backup for my computer .I use the battery in that.The unit is plugged in to the wall so when I lose power the battery kicks in and gives me time to turn every thing off the right way.It constantly charges this way and is always ready.and as I have said, the last one lasted 3 years.This one is still fine and I expect it will do the same.I do not know about the warranty.I am sure it would not be to hard to find out.

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.

Fresh batteries should have an expiration of 5 years into the future. If I received batteries less than 4 years I would return them. Thats just me...

Best I can recall, NO. But this should not even be an issue since one battery will probably last about 10 to 15 years.

Mine had a June 2009 date code, so this battery is 5 years old. I understand it's still "technically" new, as in never used, but 5 years????

Five years on today's digital devices (computers, laptops and phones) is a lot to ask, in my opinion.At about three years people generally get out of synch with all the rest of the digital world and end up upgrading.They cannot be replaced by the user, the batteries that is.I get two full days on a charge, and I watch Netflix movies and play graphics-intense games, so I mean about 10 hours on a charge.Hope that helps.

Yep! I've had mine for a year and a half now and the battery is still fine, haven't needed to replace it so far !

No sign of battery weakness in 2 years. For the 5 bucks or whatever this thing cost, if the battery goes dead, I'd throw it away and get another one.

I've had one for over 5 years now that's still going. The battery life isn't quite what it used to be, but still over a day of pretty heavy use.

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

If you check the back side of the unit you will see a label which has various pieces of information including a manufactured date. I quite sure you'll find it is probably six or more years old. That being the case, the unit must be replaced. It's useful life has been reached. It is designed to be this way. New batteries will make no difference.

Phillyphil, the description of "3 to 5 years" doesn't mean that it has that amount of electricity supplied. This battery is very much like a car battery. You can use some, or all, of it's electricity when your power goes out and when the power comes back on it recharges back up. It will live this way for 3 to 5 years. When it finally dies, it will need to be replaced. Engineer David

Nope...my guess is this unit, as efficient as it is must be at least five years old, but well worth the low price..
