tthe battery i purchased lasted about 15 minutes. i do not reccomend this product.

This last one I bought lasted me one week. Original battery was ok for about two years.

That is difficult to say. I have an use my original battery (Aug 2007) - which still holds a two hour charge under heavy video usage. I needed another for my extended travels and quick swap out in foreign countries or areas without reliable consistent power sources.

It appears to charge for about a 2 hour lifespan. But that's how long most of the 6-lithium ion batteries charge for. Most batteries last me 6-12 months before they overheat if you use your laptop frequently

I am not sure what the life span is. I bought the battery about three months ago and it drains in about 60 minutes. It has terrible battery life. I am not sure if I got a defective one, or this is just a terrible replacement part, but mine does not last very long at all.

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 also agree with Andrew. I bought this battery and simply installed it and it has worked fine ever since (more than 3 months now). I went from about 6 hours per day of life to now about 12 under normal use.

I can't say over the long-term, but I have had mine for three months, I use it everyday for hours at a time, and I have not yet had to replace the battery.

Do you mean 10 years? My Mom had her original for years and I think she somehow wore it down early. But it was still years. This puppy is working great so far. And at this price the battery is essentially free. :-)She was having reception/dropped calls issues. Her house is on a mountain. She said she thinks the connection is getting sketchier because of the battery not holding as much of a charge. I said I don't think so. Well we got this replacement battery and the call reliability seems a lot better. Go figure.

Sorry I can't provide an answer, but I'm in the same boat as you. Have you inquired about it via their customer support? I've been trying to locate the warranty information they sent with the battery so I can see what kind of stuff falls under it.

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.

I used to get about 12-15 days when new. However, as the battery has gotten older, its life has gone to 8-10 days. And li-ion batteries just die without warning.

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.

We regret to inform you the battery can not be replaced. Battery life will vary according to the frequency and length of use. If the battery is charged once every 2 weeks, the service life will be approximately 3 years.

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.

Can't find it from the manual. Suppose the life span of the battery depends very much on usage of special features like the lamp and altimeter. Otherwise, I would expect two years the minimum acceptable life span.

I find it to be about 1-2 years. Dont charge unless it is dead. Dont leave it charged over winter. If you keep it in 60-80 degree temperatures it will last longer. If you have this battery already cut off the wires and solder it onto the one in the link below. You will save 75%. 12V 5AH SLA 187 FASTON

The batteries have a life of 3 to 5 years. This is based on the batteries being kept in a good state of charge as well as being used in a appropriate temperature. The biggest factor that will determine the live of a battery is the temppetature. As the temp. rises the life goes down.

Unsure what the warranty is on this battery however I will say that its a pretty good battery for cost. No issues as of yet.

I've only had this battery in operation for 1 season. It's out of the car for the winter. Life has a lot to do with usage. I feel that the life will last for several seasons but obviously it will take several years to confirm.
