Compared to Nikon-branded, how long will these store while still retaining a charge?

Last as long as my two Nikon batteries. if you leave any of the rechargeable batteries for more than a month the lose about 50% of their charge.

I can't say. I always charge all my batteries before I leave home. These batteries showed no loss of charge after two weeks and lasted slightly longer, took more photos, than a one year old Nikon OEM battery. I can recharge from my vehicle lighter socket so beyond two weeks or a month is not important to me. Given their similar discharge rate in use, I would guess that the discharge rate in storage would be similar as well, but I can't say for sure.

Any time I take my camera on vacation, or before I take it anyplace, I put a battery in the charger. I have seen no difference in these or the Nikon brand while using them. Much cheaper then Nikon.

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer

The charge should hold well. I have had my glasses for a few months and have only charged them up the day I got them. If you charge them after every use I think you will end up having the effect. You don't need to charge then after every use and the charge is good for a very long time.

Not long, 2 or 3 months at the VERY longest. This is a trait of the NiMH batteries, NOT the brand. Personally, I would top-off any battery I was planing to use during an electricity free vacation, no earlier than a week beforehand, in order to have the most juice on hand when you need it. This is from my personal experience with a wide selection of brands and a wide variety of battery ages. Everready, on the other hand, claims that NiMH batteries in general will loose 50% of their charge in six months. I expect this may be the case under the very best laboratory, tempature and humidity controlled conditions. Not under normal conditions, like your camera case, electronics drawer, or your battery shoe box. Now... While I've never seen a STORED NiMH battery hold a charge that long, I HAVE found that using them in something that draws a small, but constant current, will give you a MUCH longer shelf-life than charging them and then storing them. Depending on what they are in, I've seen them last up to a year or longer.

I have had no issue with my Progo EN-EL14 to date. The only thing I've noticed is that it doesn't appear to hold a charge as long as the Nikon battery. I always keep one in the camera and one in the case fully charged. So far, I've not had either discharge while idle.

And you said you ARE using genuine Nikon batteries? I read where some of the cheaper batteries do not have a chip that nikon cameras read as an authentic battery. A lot of the grips are having problems with "non-chipped" batteries..... Just a thought

Yes, I have had my camera using this battery for I think 5-7yrs and my original batteries were not holding their charge, so before I bought a new camera I decided to see if the batteries were the problem ,so I bought 2 new ones (I always have a spare) and charged them up and I think that was the problem, so I guess my point is that, the batteries last 5-7yrs, not a bad investment

I purchased these batteries for our 3 week trip through Europe and they never failed once. Used them in a Nikon CoolPix L820 and the camera worked flawlessly. The battery indicator always showed full charge, until the charge was depleted, reason I bought 2 sets, and we always had the backup with us. At night I would charge the depleted set and by morning they were ready to go. During the entire trip I had to pull the charge out 3 times, and we took over 1800 pictures with the Nikon. Hope this helps.

one of mine stays charged after charging and before use for about 3 weeks before depletion but the other one loses 50% of charge in same time frame. The battery when fully charged remains charged for a very heavy weekend of photography. The Nikon battery lasts for weeks. I bought a backup Nikon battery just in case while out in the middle of nowhere, I'm guaranteed a charge.

I have an HDR-CX160 and they work fine in that camera. I get almost 5 hours of continuous use off a full charge.

I have two Nikon batteries and keep a fresh one with me all the time. I purchased the Nikon D80 from Amazon as well as the spare battery and have had them for about 5 or 6 years without any problems. We, my wife and I take pictures oround the southeast and take pictures of wildlife almost every day. Will the battery last a lifetime? I don't know if it will last as long as we live but both batteries are still working just fine after being used almost daily for approx. 6 years. Hope this will be of some help......Rich

I checked and the batteries I recently purchased were 1250mAh. The original Nikon battery is an 1100mAh battery. I am not sure what effect the higher current rating will have. I have used the two replacement batteries and so far I have noted no issues, but long term???. Thanks for bringing this to my attention; I do not know how I overlooked such an obvious difference.

I've had pretty good success with these batteries. I put a fully-charged battery in my camera before my niece's wedding last Saturday & started taking pictures at the church at 1:30. I took several hundred pictures (don't know the exact count on this battery) and didn't have to change the battery until about 7:30 that evening. I always keep a fully-charged backup in my bag & the second one got me thru the rest of the night, with charge to spare. Hope that helps!

Hi, seems to take an hour or less to charge, and they have lasted for several days of use, depending of course on the number of photographs taken

Brilliantly in my experience. Been using them for weddings, as primary batteries. I can't remember now, but I believe in my review I put a number on how many shots I got from them. I purchased them before I did the firmware update, and updated after my 1st or 2nd use, they still work wonderfully. The only thing I don't know if their longevity...I'm not positive these will last as long as OEM, but so far I have absolutely no indication that they won't.

We were mainly taking pictures, when we were on our trip. And they lasted longer than the one that came with the camera. They lasted about a day and a half of off and on use. With the two batteries you should be good. I hope this helps you.

I've had them HOLD there charge for 4 months of non use! up to 2 months of off and on use and for at the irish fest shooting and video taping 2 - 4 hours depending on how hard I'm going They do hold up well I cannot complain! Those batteries that only cost a few dollares and ya I've tried them! NO.....don't hold the charge for long and don't last that long either. I've had the cheapies go in 2 - 3 years you know freshly charged and Dead in 30 min.
