How long does a charged battery hold it's charge? I am going on a backpacking trip and will not be able to recharge for 3 weeks. 3 batteries enough?

I have a Nikon Coolpix camera, and my batteries would last for about 120-140 pictures. I took that many pictures a day, so I would swap out every other day, and recharge one each night. At home, I only take a few pictures on occasion, so the one battery last for several weeks. So it really depends on how many pictures you will be taking daily.

The charge is different for everyone. Depends on how much you use it and what you do with it. When I use my camera several hours at a time I find I need to recharge daily, but if you don't plan on using it a lot 3 should be OK. You might look into a solar charger. I don't think they are very expensive.

They usually hold pretty well. What drains them is taking pictures. I'm not sure how many pictures you can take on one battery. Would you have time to take pictures with one battery and test how many shots you can get before it runs out of juice? I think that's what I would do to figure out how many batteries that you need.

I would do a "test run" with your camera to see how many photos you can take during a day. It may be help to remove the battery each day as some cameras will drain the power. I have never been away from charging power for that length of time so I can not give an accurate answer.

They will retain their charge for several months if they are not used, and not stored in the camera. If the battery is stored in the camera, it will lose its charge in about 1 week -- apparently the camera (at least my S570) draws some current even when the camera is shut off. I suggest to take the battery out of the camera if you are not using it. How many pictures a battery will take depends on many factors -- like whether the flash is used, how hard the auto-focus has to work, size of the images, etc. With the flash off, and using full resolution jpg images, I can get at least 1500 shots on a battery charge.

You can go quite awhile once charged...I think at least a month if not more. You did remind me to check mine though since it has been awhile since I charged it! ;)I've never kept it plugged in though...only plugged in overnight to charge it up and it holds a charge for a good duration of time!

Going by the comment section I ordered 3 batt. The reason for doing this was to have an extra battery because I was going to be away from any charging source for 3-4 days. Two of the battries were good the other one loses it's charge quickly.

I forgot to turn it off after shutting down and the charge lastest about 2-3 weeks. I'm guessing now that I turn off and have recharged it, it should last for several months. Or maybe not.

Depending how long you have had it the battery may need replacement. Keep in mind rechargeable batteries have a limited number of charges depending on the model. Some are 50 some 100 charges. Also unless you have a special trickle charger you may decrease battery life if you keep a rechargeable battery on charge for more than 2-3 days at a time. This holds true for most rechargeable batteries.

At least two weeks. I once charged it fully, unplugged it, put it in my backpack, and did not use it for about two weeks, and it seemed to have maintained its full charge even after that whole time not being used. Just remember not to have anything plugged into the USB port when it's not in use, otherwise it will drain all of its power by itself (keep it unplugged unless you want to charge your device).

Just like any battery, it depends on how often you are transmitting or receiving.We take these camping for 3 or more days and use them to caravan.With the FM radio on and scanning two way communication they last 2 to 3 days before needing recharged.In the manual it tells you to cycle the battery,Fully charge it when you get it then totally discharge it. Charge it a second time and its ready to go.

Depends on the batteries, I use interstate 3000mah rechargeable batteries and it still has a full charge after using for days, every battery is different, even rechargeable ones, best bet would be to buy a good pair of 3000mah batteries or better and you'll never have to stop short in the middle of a vacation to buy batteries

Charge times for me were in the 2 to 3 hour range and a good 15 minute flight time. It dosen't sound like much but surprising it feels alot longer than really is. I bought spare batteries at a cheap price and kept them charged. I would average 45 minute outings with 3 batteries. which was more than enough given we took extra helo's and made a day of it.

You need a new battery pack! The battery charge should normally last for at least a week.

Yes this is to be expected even with the four hour charge time the internal battery only last 20 minutes. The best thing i found to do is rip out the internal battery pack and use a triple A battery holder in its place with 3 rechargeable triple A battery's. look-up on YouTube for help.

When it is set to 12amp charge they say it takes 14 hours from empty. I rarely run my batteries to empty so I am able to recharge my batteries overnight - about 8-10 hours depending on how low my battery level is.

One full charge last about 3-4 hours game time for me. The battery does drain really fast. If I charged fully, it only takes about 3 days to be out of power. However, the real problem for me is that the battery is unable to hold any charge at all, after 3 weeks. I only charged it like 8 times. I had to return the product. Right now, I really wonder whether or not it's just me or others have the very same problem.

For me the batteries lasted quite awhile. I used it for short term trainings and a trip to Africa. I only used it at night when I was sleeping. If used more than that it might not last long. I didn't try rechargeable.

It takes mine 8 to 10 hours for a complete recharge. I dont leave it on charge all the time. My last Battery lasted three years good for a lead acid battery.

I have three (3) eight hour batteries to ensure 24/7 availability. The eight hour battery lasts about 7 hours on 3 liters. When I am very inactive, I reduce it to 2 liters and it lasts about 8 hours. I purchased a camera assessor bag to carry the extra batteries and power cords. Great product!
