Typically, battery can last up to 3 years, if kept on regular charge cycles. We recommend changing battery every two years.

would probably depend on how much it is used (power outages) The original in my upc had lasted about 6 years. This one is going on 2 now and still works fine.

I like to replace SLA batteries after about three years of service. I've had a few that have still been spry up to about five years of use, but most of them start to drop off in capacity and run time before that. - Greg

I used the battery in a robomower lasted less than one year. Contacted manufacturer for warranty got replacement after about 3 weeks wait.

Quite a while. I have owned this for well over a year now, and I have only replaced the batteries once.

About a year and a half. I tried replacing the battery and it didn't work anymore after that.

Two years sounds about right, actually. My mower came with a battery, and after the first couple of years it would not hold a charge as long. This is battery number two.

I have had mine for about a year now and still have the original battery in it, and working!

I have used mine for at least 4 hours. After 6 or 7 years it still lasts over 2 hours.

Battery will last over a year ... just put a new one in it before you leave.

My husband seems to think that it's guaranteed for at least 3 years, but I'm really not sure and couldn't find anything related to a guarantee. On a separate note, the previous battery lasted for years and this one is working fine.

I've had mine for about a year and use it for about 4-6 hours every day. No problems.

I had my original battery for about 3 years before I purchased a new one in May 2014 still working with no problem.Depends on the phone and how much you use it

I'm using it for about 3 years now and have no major problem. Probably the downside only the charging time longer and lifetime shorter than the original, but really worth your money for backup battery.

I forget, but I think it's 3 years. Mine is working great, and I bought it in 2012. It packs plenty of power for the price. Good deal. Glad I bought it.

From my experience, the life expectancy is about 2 years. The only reason I keep buying these batteries is because I have several pieces of equipment that uses this battery and I don't want to just throw them away. I have about 4 of these batteries and i keep one in the charger most of the time. I have thrown away about 3 of them in the last 5 years. The battery will do well for about a year and then it will lose it's charge sitting on the shelf. I'm guessing these batteries that we are buying are several years old when we receive them. Sorry to tell you this.

To me, it lasts at least as the original when it was new and maybe longer. It is really hard to tell without all parameters being equal in a head on replicated test which of course i have not done. Under my normal use I am getting through the day every day and still have about 50% of the charge left, where as my old battery that was greatly reduced in its ability to function correctly was often not getting me through the day and in some instances dying during the morning hours. In the older batteries younger life it did last all day and I would then again charge it overnight.

I use these batteries in some burglar alarm sensors, and mark the date of installation. Most of the time (in at least half a dozen instances), I will get between 2 - 3.5 years of service on the Ultralife batteries. It's not 10 years, but it is far more than I would get from a standard alkaline.

Like the others said I guess it's in the item specs. To be honest I've never had to replace them or anything. I have two of these and one has been going for a few years. Admittedly they only get used on occasion but the batteries have held up.

I own two of them and one is three years old and still holds a charge as if it was new. I would think it would last longer.
