I have recharged my cannon batteries multiple times in the past 3-4 years or more. At what point do I need to replace them?

I replaced my original Canon battery, the one that came with my Canon Rebel XT, after 4 years, during which I took a lot of pictures. If you are having to re-charge the battery more often, and the charge is not lasting as long, it might be time for a replacement. I would recommend staying with the Canon brand batteries. There are cheaper alternatives, but I'm not sure if they are as reliable.

To be honest, I don't know exactly. Once you notice less performance or faster loss of power I would replace them. I usually have 2 anyway, so you are always ready, when one is charging.

If you have to recharge it more and more often, then the battery is near the end of its life.

I can't answer that directly as it depends on use, I expect. I don't think I've replaced one in over 5 years, but I always keep an extra on hand. I did buy one that was a dud, but think it wasn't a Canon one. Would never again try to get a cheaper one. Not worth the savings. I would recommend getting an extra new one to keep on hand if you're traveling, but sounds like yours are still going strong at this point.

Hi, If you only take a few photos at a time, you do not need to replace them until the battery not able to met your need. For example, if you like to take photos of your kids on vacation, a two week vacation, you may take over 1000 photos when the battery is new. And now if your battery only last you 300 photos and it is your only battery and no place or time to recharge. It is time to replace it.

I use rechargeables in my machine and they last about a month of twice daily usage (with the 3 averaged readings and some clothes in the way errors with an extra reading twice a week or so.) I estimate that they need replacing between 180-200 individual readings.

From my experience I wouldn't attempt to go over an hour. I had three batteries charged and ready at all times. When one would get low I would change it and put the used one on the charger. If you are shooting continuously go AC if you can't use AC keep an eye on your battery level. I hope this is helpful.

I have found that the more you use these batteries the better they respond, if you use them infrequently and don't charge them at least once a month they loose their ability to hold a charge in a year. However, if you use them and charge them once a month when they don't get used, then 3 to 4 years.

Don't know, but a long time. Mine has never needed recharging. I have not used them a great deal, so this is probably not very helpful.

I ended three years of use four months ago and my battery is now dying out as well. I used to finish my lawn with one charge, now it takes two. I am contemplating the purchase of another battery, but at $149 it is definitely causing some sticker shock.

I read somewhere you shouldn't leave the batteries and a charger. I have for tools now that run on those batteries. I use them in a commercial capacity And have for 5 years.

If you want to ever replace the rechargeable batteries after a year or two, any rechargeable NiMh AAs will do, I think.

I used to work for a battery company. If you keep them charged you should get 3-5 years out of them. Store them in your basement or somewhere cool. Do not freeze them ever

I use Duracell batteries, but I do not use it in the same environment as you. I guess would check every 30 days or so. I would worry more about the electricity going out.

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 have bought 2 one lasted almost 5 years and im on the 2 , change the batteries and see if that corrects your problem.

You need new "rechargable batteries" I find I need to replace them about every 9-10 months, depending on how much they are turned on. We both watch TV about 6 hours a day and more on weekends. Ours screw up when they are not chargring in their unit.

I use a pair of higher end Energizer Lithium AA batteries and they need to be changed about once a year.

Agree with Frank ... some lithium ion batteries have a life span of as little as 3 years. Yours is likely closer to 10 years old. Before you replace the battery, though, plug the camera in to power and see if it will turn on. If not, it may just be time for a new camera.

I replace the battery itself every time I replace my vehicle battery. About 6 years. They still seem to have enough power to sound the alarm but I change them anyway.

I have one that I've been using for almost three years and it's still going strong. Just change the batteries when it starts getting sluggish or acting weird and it'll come back to life.
