I've a bee in my bonnet about these tonight >:(
Two chargers and about 12 of the things. I recharged them a few days ago (prob 3 days) and put them in my camera tonight for my pizza piccy..............8 out of the 12 gave me a battery low reading!
Are they really value for money when you consider the recharging costs, since we can now recycle the old type batteries that last for ages?

which of rechargeable battery varieties are using.
I keep my camera with the recharge batteries still in on charge when ever I am not using my camera. same batteries I put in when I bought the camera about 5 years ago, no problem.

I had the same problem with rechargeable batteries. Dec 2008 I bought 2 lythium camera batteries. I replaced them in Dec 2009.

Does that not make them more expensive then than normal ones qahtan, with keeping them on charge?
I use NiMh batteries in my camera, been using same ones for 2 1/2 yrs, still hold full charge.
(you MUST FULLY discharge batteries before re-charging, especially when new, otherwise they won't take a full charge it's called 'battery memory' ) ;)
If you are using cheapies from poundland etc, you might just as well crap in your best hat, for all the good they are.
Get decent branded named batteries and follow the charging directions especially the first charge.
I had some freebies from Jessops in a camera deal a couple of years ago, strangely enough they are still working. I noticed in Robert Dyas the other day that they were doing the good ones, but check out the other shelves in there as the same batteries with a charging unit were cheaper.
When I bought my Panasonic camera in 2004 I also bought two spare batteries (third party) and all three (BM7) are still in use with no problems. I bought the spares from a firm in New York (no, not Lincolnshire) they cost less than £13 each including carriage.
Batteries come in all "powers". Which battery ad has the bunny going on and on and on...? Rechargeable AAs are labelled with x mAh. 1300mAh is around the "cheap" low end, and the 2650-ish is at the heavy duty end. 2000+ mAh is ok for cameras...
A mixture here of:
GP 2100 NiMH
Vapex 2900 mAh
Uniross 1300 mAh
and two chargers:
GP Powerbank Quick 2 and an Enigizer.
I can get enough power to download pictures from camera to computer after about 20 mins of charging but then they die. If left to charge overnight, then I can take pictures leave them in the camera for perhaps a couple of days, take a few more photos then download and that's enough for the batteries.
Maybe I'm expecting too much from them :(
Thanks for your help and sugestions, perhaps it's time to invest in some new ones then!

use a card-reader to download photo's?

My Fuji camera card isn't compatable with the laptop slot, so I guess that's another bit of equiment needed, Tony ;D

There's the problem, mixing batteries with different mAh values will reduce the effective capacity of the set as a whole. The lower powered batteries will discharge first then the higher rated batteries will attempt to charge the lower-rated battery in reverse probably at a much higher current than a charger would use, even in the correct direction. This quickly kills the lower-rated battery often permanently NiCd & NiMH cells can outgas (burst), Li-Ion can catch fire, obviously this could damage your camera.
In the future I would suggest using batteries of the same type & ideally the same brand & age.
I've got pairs of the same ones Baccy Man, and only use those together, ie not two different makes in the camera at the same time. Maybe it's their age then.

Can you still get Nicads ? I thought they went out with personal tape players - the original Walkmans.
Also I didn't think the NiMH batteries had a 'memory', that was just NiCDs.
I try and only by one set from each manufacturer so that I can identify matching 'sets'.
Nickle Metal Hydroxide (NiMH) are certainly the thing to have. I've recently changed all my 1300mAh for 2500+ at around £10 for 4.
1- Mine must be at least 5 years old by now and must be reaching the end of their life (max 1000 charges)
2- They don't last as long.
3- They just don't have the grunt required by modern cameras. They may be fully charged and work well in other things like torches and remote controls, but cameras have a high current demand, which the lesser batteries cannot supply.
Also, you need the correct charger for the type of battery, Nicds dont charge at all well in a NiMH charger and vice-versa.
I charge mine in a 2 hour rapid charger and if I know I'm going to take alot of pics I'll charge all the spares whether they need it or not.
I keep the camera in the car, mainly in case of a RTA. even if I dont use the camera, I will still change the batteries every month or so, just to make sure they work when I need them.
Rechargeable batteries have a lower voltage, 1.2V instead of 1.5, not a problem normally, but check your manual to see if you need to change any settings.
Rechargables do self discharge, normally weeks, but the highest capacity can self discharge in a few days.
You should not leave batteries in perminent charge. If you have a smart charger then no problem, this will detect when the batteries are charged and then switch off, or switch to a low trickle charge, but if it is just a basic charger, it will heat the batteries, which damages them.
Someone mentioned, the `memory affect` where it is a good idea to fully discharge between charges.
While this is considered good for Ni-Cd, it is not relevent for NiMH.
Never heard of Vapex, but the others should be fine.

Neither has a memory but they both suffer with voltage depletion (NiMH to a lesser extent). If a battery is repeatedly charged after it has only been partially discharged it will develop a lower voltage and a lower capacity. This effect is reversible by conditioning. Conditioning is simply fully discharging the battery (down to about 1.0 V per cell) after charging it. If a full discharge followed by a charge cycle is done several times, a battery suffering from voltage depletion should be restored back to its normal voltage and capacity.
Overcharging which is much more common causes similar effects (reduced capacity/shorter lifespan) but is irreversible.

I don't understand why you need to charge the batteries to download to a computor. Surely the usb connection also charges the batteries in the camera. I have a car cigar lighter type of usb adapter for charging the camera and everything else with a usb connection that has batteries. I have left my camera plugged into the computor sometimes just to charge it up. They are the normal AA rechargables.

Are these any good ? I wouldn't have thought they have the circuitry to cut out when the batteries have had enough, thus blowing the batteries.
My first digital camera (back in 1998) didn't have a USB, just to upload a few pics would drain the batteries. So I got a USB card reader, alot easier to use, quicker and much less expensive on batteries.
I think all cameras these days come with a USB connection for uploading pics.

Some do, some don't, just depends if the camera contains the circuit to charge the batteries in-situ or not.

They just provide the same power as a USB on a computer would give, the camera has the charging circuit so it depends on the camera how the batteries get treated.

They have usb card readers in the poundland. Takes all sizes of cards.
