I don't need a replacement battery at this time. If I buy this battery now and keep it in storage, how many years would the battery still be usable when I need to use it when my old battery dies?

Less than a year. Sealed lead acid batteries need to be kept on charge or else they undergo something called sulfation, which is terminal to the battery. Buying one ahead of time and storing it is a bad idea.

I've never needed to replace it but it's an L1028, A23 battery. (I guess I should update my review to say that it's been in use constantly and the battery is still fine.)

Not a expert but my experience w/ similar type emergency lighting batteries is 2-4 yrs. They actually would last longer if receiving a discharge/charge every 3-6 months. Probably why people report these go bad after 3-4 yrs because they rarely get discharged/charged. If you do buy a spare keep it in a cool place and that will help the shelf life.

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.

I would imagine being that old it would be difficult to find a replacement battery. A battery will go bad just like a battery in a car it will eventually go bad and need to be replaced. I haven't had this problem the handle on mine broke and could not find a replacement so I had to puachase a new one.

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.

I've not had to replace the battery. Perhaps the manufacturer could give you an answer. Locally we have a store that advertised they have any kind of battery needed so if I did need one I'd try that store first. They might have economical batteries and would be a local access if you needed more batteries in the future . Sorry I couldn't be of more help.

Don´t know how long you´ve been using it for. If it is 1-2 yrs max with a minor-moderate usage I suggest you contact the manufacturer. I did it once at the beginning and they provided a great/quick service. If you´ve used it for several years then you have to understand that all batteries have a life. Maybe you´ve drained it a few times and it´s over now.

Since I purchased the Hewlett Packard battery, this is the information straight from their website: "Lower Total Cost of Ownership: One battery has an up to three year cycle lifespan, reducing your overall battery cost since you purchase fewer batteries over the life of the notebook. Flexible Solutions: With up to three years of warranted performance, you can enjoy the entertainment and productivity features of your notebook for longer then with standard solutions." Of course, the actual lifespan of the battery will depend on actual usage and care. It took me three and one half years to need replacement for the first battery; so far, I have had this replacement battery since July 16, 2013; I do not run the Notebook on battery only for long. I make sure to charge it as soon as possible. Hope this helps. Good luck.

All batteries have a finite shelf life. A *great* shelf life for a battery is 5 years. Most of the older battery technologies wouldn't come close to lasting 5 years on the shelf. Statements like "these batteries will last 10 years on the shelf" are optimistic, for pretty much any battery made, although Lithium batteries can last that long (to about 70% of their fresh capacity). Frankly, at the price these batteries are, I buy them and use what I need. If in 2017 or 2018 I don't find I am getting good service from them, I will buy more for less money and be happy about it - just my opinion. The do say "Use by 2023" on the back label of the package. Depending on the Storage temperature your mileage may vary. Do not freeze batteries, but keeping them cold can extend shelf life. Also, do not use cold - warm them first, as battery efficiency is drastically reduced at lower temperatures. So batteries stored in the refrigerator should be warmed to room temperature (NEVER in an oven) gradually before being put into service.

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 !

I have three of these and they don't usually die but I have one not holding a great charge after 2 years. Since the warranty is only 1 year, the company will replace the battery for a fee. But you do have to send it in. Don't open it yourself or you may hit something inside. There is also a reset hole in the silver ring bottom. Push a pin in it for 5 seconds then hit the on button for 5 seconds and see if the reset charges the battery. Best of luck.

If you mean Shelf life. A Long time at least 5 yrs possibly 10 but in use It all depends on the load of device they are used in Mine was in the remote for our Lexus and it lasted little over 2-1/2 years so if it has been in use in a device you might want to get a spare ! Keep new batteries in refer. Until needed they last longer when kept cold . And the 2011 is the copyright date not the manufacture date you are right no use by date !

The battery usually last about 2 yrs. I would get it diectly from the seller, I did and the seller sent me a new one right away, but again that will depend on your seller. To remove and insert a new battery is very tricky, so it takes some tweaking. However, if you just bought the product, send it back for a new one. I'm very happy with my two.

That is when the battery was made. It should still be good. They usually have a long shelf life

hello jboo I got some of these batteries and it says on the back "use by 2023" so they will store along time I`m guessing

I've been using mine for about 8 months, so it has not run out. The product comes with a claim of some very large number of hours of run time. It is important to gently dry it off before putting it away since moisture is what turns it on and when dry the battery should not be needlessly drained. On U tube there are instructions available for replacing the non-replaceable battery oneself, but this might not be needed for years if the claimed number of hours of service is true.
