how long will a charge last in a fully charged backup battery that is standby and not in use?

I cannot give you a specific time....but, they do not 'run out' or run down noticeably fast. I have had not 'commplaints'....the battery runs the same as the Canon one

The description states that the cells are made in Japan is all. If this is true then they should be quality cells. Also lithium batteries last nearly forever if they are stored at about 40% of charge. It is the number charge/discharge cycles which slowly shorten it's life. Also don't believe the mah rating. After market manufacturers simply lie about a battery's capacity because who is going to pay to do the testing and hire the lawyers to challenge them. If a lithium battery is about the same size, weight and price it is about the same capacity.

I always keep an extra battery charged and they keep quite a while, I have had them stay charged for a week or more, I usually use them by that time but I have no idea just how long they will keep, I have one that I keep in my car for another camera and lord knows just how long I keep it, of course it doesn't stay fully charged but enough that I can use it for quite a while.

My Photive battery does not last more than a few shots when I pull it out to replace the depleted Canon battery. I have had the Photive for 1 year. I would not buy it again.

Mine dies completely within a week. Or did, that is...I tossed it. For a casual user my regular battery lasts for weeks so I don't need a backup.

When new, the battery lasted 45 to 60 minutes after a full charge. The second summer season, a full charge resulted in only 30 to 45 minutes. This summer will be the third season, and I hope there isn't another drop.

When y battery arrived, it had about 1/4 charge. I charged it for 24 hours and it has worked great since. I'm happy to have a fully charged backup battery at all times.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.

It hard to say but I leave mine on charge the day prior to using for a period of time. I can get about 7hrs playtime.

The first charge should be 14 hours to give your battery full capacity charge. Then, one 3 hour charge will last for about 36 hours, or you could charge it every night like smartphones.

I would say I get a good 10-15 hours of runtime on a single charge, and standby time is also pretty good, charges up pretty fast also!

I charge mine over night and then use till it starts to slow down then over night again. I have forgotten about them in the charger for about three days, they were hot, and over the years it seems to shorten the life of the battery. so 8 or 10 hours for full charge.

I'm not sure, because we use it as a battery backup to our server. The times I've needed it, we've gotten at least 2-3 hours of backup for our server before our electricity came back on.

A fully depleted battery should be fully charged in about 3 hours. Thank you

Typically with lots of use it generally lasts 1-2 hours depending on use and takes approximately 3 hours for the battery to charge up to full capacity again. I hope this helps with your decision.

The battery lasted about as long as most. I bought a back up, so I never worried.

Mine runs a minimum of 30 minutes on a full charge. I've never run it out so I'm not sure how long it might last.

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 know there is a battery backup, but I have mine plugged into an outlet. I don't know how long the battery is supposed to last, but I wouldn't recommend it as your primary source of power.

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

I would charge it for a full 15 hours before using it. They usually come partially charged, so doing a full charge is the best way to be sure.
