I've been using it for about a year and am very happy with it. Great battery at a great price.

I have no issues with this battery. I run my laptop for hours at a time typically, so I keep it plugged in. If you were to run as little as possible, I'd say it would probably last an hour or two.

To begin with, this battery seems to have a history of problems. So far, my experience has been positive with no problems but I have only used it for 6 months. Checking water level would be my only recommendation.

I have for the last two years. I only recharge the battery 2 or 3 times a year. I don't overcharge it. so far so good.

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.

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.

A long time. I've only had mine about a month never had to charge it yet after initial charge

That is a good question. I have had it for 5 months and it's still running on the same battery.

I received my battery last March (2012) and fully charged it up to use mainly for an emergency or when I travel. I had really forgotten about it until you asked this question. I just took it out of the drawer and found that it is still charged up to 99%. This surprised me as it has been just sitting there for 11 months now.

I don't know yet, it still has the original battery from when I bought it. Two years ago I think.

I don't remember. But, I have had the battery 2+ yrs and holds charge very well.

I used the first one of these for 2 years and have just recently replaced it with another, It lasted as long as the original battery, with about the same run time

My battery has lasted a long time. Don't know exactly how long but a lot longer than 9 months. Maybe you just had a bad battery.

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 use mine almost every day, and haven't changed battery yet. Bought mine eight or nine months ago. :-)

The camera for which I bought this battery is still new to me. I bought the battery as a back-up and have only charged it once. It is new and my past experience with other lithium-ion batteries for other cameras leads me to believe that this one will continue to do its job for at least two or three years. Sorry I cannot be of more help.

Sorry I have not timed it but I deid note that it lasted at least as long a the much more expensive Canon battery; perhaps longer.
