Battery life depends on how much time unit is in alarm condition. If it never goes off, they'll probably last a year, but it also depends on the batteries and the environmental conditions.

A great way to keep batteries fresh in devices such as this one is to change the batteries every time you change your clock for daylight savings time.

The directions say to replace the batteries (it takes 3 AA batteries which are included) once a year. It will give an audible and display signal when the batteries need to be replaced also.

Your current usage will determine how long the battery will last.If your running it to full capacity,then it mightn't last too long.

I don't know if you are referring to the battery or the camera? I find the battery does not last long, which is why I bought this additional battery as back up. I keep it with me while I am photographing. If you review your photographs on the camera after you take them, it uses up a lot of battery power, so I do not do that. Depends upon how many photos you take. If I am out all day photographing, the battery might last for one day.

Brand new with average use it will last more than 20 hours. Do not make the mistake of overcharging the battery. Disconnect right after it is fully charged. The battery will start dying faster which happened to me.

Hi Meghan, I doubt anybody would take time to compare and find out how long it lasts. To me, they are the same. I have been using generic battery as long I can remember. No problem so far.

Let me say befor my answer that this gadget is really awesome ...IT IS battery operated.....how long does it last?. It depends on the way you use it,I do not keep it going for long periods,and still works fine.but if you keep it on for several nights it will go on for several days,as for the batteries ,it needs 3 small rounded ones.TAREK

But, to your second question, the battery is not replaceable. There are sites on the internet where you can find out how to replace the battery though. My guess is that by the time the battery dies it will be time for a new model anyway. The battery should last at least 5 years I am being told.

How long will it last? - I think the real question is - does it do what you want it to do? For me the answer is no. I would not recommend buying this product.

Since I don't have a big yard, I have no complains like those other users, except that I cannot find a battery replacement, and I need one now. I checked at Sears but no one knows. I search all over the Internet but no result. I even wrote to American Gardener Co. but got no reply. If we cannot find a battery replacement I suggest DO NOT BUY this item. You'll just add garbage to the landfill in a couple of years. HOW COME NOT ONE REVIEW MENTIONED ABOUT BATTERY REPLACEMENT, AND WHERE TO BUY IT? AM I THE ONLY ONE THAT HAVE THIS ISSUE?

Good, I assume. I have been using it 8+ hours/ day for 5 dats a week and I've had it over a month now and haven't had to replace the battery yet.

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.

Battery life depends on usage and battery condition, as batteries are a consumable item with limited lifespan and performance will gradually decrease over time. That said, I would expect a battery in good condition to last 3+ hours under light to moderate use.

No, the rechargeable battery inside is not replaceable. I use mine almost every day for over 8 months without any change in battery life. If you're worried about the battery not being able to hold a charge in a few years, then you may want to contact the manufacture to see if they offer a battery replacement service.

I've been testing mine out recently - I run for about 2hours, 2hours 15 mins. It usually lasts 2 such days - so 4- 4 1/2 hours- which is quite disappointing. I have a feeling indoor battery life maybe slightly better. I was looking for the "rated" battery like myself. Would be nicer if it went a week without charge.

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable.Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

Don't really know what to tell you for sure. It is kind of a guessing game as what will work best for you. I am happy with my purchase, my battery was so weak that I had to stay hooked to electric (only had about 20 minutes on old battery) this one works just like a new one should. I don't think any of the batteries will do exactly what they say. (seems just like a guideline to me)

I'm not entirely sure on that. But I've been using mine for a 3-4 months and haven't replace the batteries once. I use it on the go, so I turn mine off between uses, but I have forgotten to turn it off from time to time meaning it's on for 24 hours or so. Still have not needed new batteries though. Hope this information is useful.
