Anyone know how long you should expect digital camera batteries to last for? Jo's had canon camera since christmas and bought a couple of sets of Jessops AA's 2500MAh and now they don't hold their change at all well. They're always fully charged and run down before being recharged.

as long as you let them run right down before re-charging them they should last a couple of years

the problem is they are filled with a gel and each time you charge the battery the gel hardens and a lot of people just charge as and when,so if its not dead (sort of half charged) you are hardening the gel half way up

if any of that makes any kind of sense :rolleyes:

I use 2600ah ones in my Fuji s5600 and they last for hundreds of shots, but I always let 'em run right out and I charge 'em for 14-16 hours, these fast chargers aren't all they are cracked up to be. Be aware that an alkaline battery (duracell and the like) will lose it's charge progressively, where as a rechargeable (NIcD or NImH) will drop off quickly once it is discharged, ie with a duracell I will still have 20 - 30 shots once the low battery symbol appears, but with a NImH I'll have about 5 shots left once the low battery symbol appears. But the NImH lasts a whole lot longer.

thanks - what do you think the life of the battery should be though, cos i've only had them 9 months.

A couple of years, the more you use 'em the longer they should last. Never leave a cell charged for a long period of time without being used. Does your camera or charger have a deep discharge function? The Fuji does, this will drain them right down ready for recharging.

Isn't there a different charger for NImH's? The one I have has a flip switch depending on whether you're chatging NiCads or NImH's. I've got no idea what the difference is though

if its happening with the same camera with different sets of cells, it could be down to the makeup of the camera, some compacts drain cells like theres no tomorrow, spesh if you use the lcd screen alot to take your shots, or if your camera dosent have a sleep mode so you walk around with it on most of the time, take the cells out when not using the camera too,
depending on if it is doing it to different sets of cells it could be a fault in the camera itsself, try asking on one of the camera forums for people with the same model, rather than going into the shop first, as they may just try to fob you off, I had a cannon ixus which used a Lithium Ion, I bought it for the wife, as I used to sell cameras at one time. didnt matter what capacity I bought it drained them, this was just the type of comapct it was.

this is a copy and paste..but explains it a bit better than I could take the time typing it out :D sorry its long but worth reading. :crazy:

The main difference between the two is that NiMH battery (the newer technology of the two) offers higher energy density than NiCads. In other words, the capacity of a NiMH is approximately twice the capacity of its NiCad counterpart. What this means is for you is increased run-time from the battery with no additional bulk or weight. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the "memory effect". NiMH batteries are less prone to develop this problem and thus require less maintenance and conditioning.

The Doís and Doníts of Battery Use

Battery Do's:

Fully charge/discharge battery up to 4 cycles before achieving full capacity of a new battery

Fully discharge and then fully charge the battery every two to three weeks for battery conditions.

Run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.

Remove from the device and stored in a cool, dry, clean place if the battery will not be in use for a month or longer,

Recharge the battery after a storage period

Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.

My new battery isn't charging. Is it defective?

Usually NO. New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity

It is generally recommend an overnight charge (approximately twelve hours). It is normal for a battery to become warm to the touch during charging and discharging.

When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not ìbroken in.î Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

How can I maximize the performance of my battery?

There are several steps you can take to help you get maximum performance from your battery:

Prevent the Memory Effect - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.

Keep the Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.

Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery procedure described above.

Battery Storage - If you don't plan on using the battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.

Sealed Lead Acid - (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.

cheers but don't think it's the camera as it used to be great. Over 100 photos with the flash & screen on probably. And battery still had charge after being in the camera for a couple of days.

the only other thing you could try, but it means spending more money, is to buy a pack of cells with a charger that comes together, I did this for my fuji 9500, at least then you will know you have new cells and that the charger will be ok..unless your luck runs as good as mine does and its also naffed, and go from there, it could be down to your charger, not sensing the charge correctly, or the drain. and could have naffed your cells up or just not cycling them correctly.
