448040	2006-04-20 22:12:00	Ok when i got my Fuji camera i got 2 packs of rechargable bats with them, 2100 and 2300? (AA) nimh or whatever it is called...... means moving and finding info....so i wont...:D 2 yrs ago at least???? :stare: How longs as in yrs should they last? and as they are not holding charge or operating the camera long im presuming its the bats lives that is had it....... they charge for 20 mins and it says done........ time to get new ones? and do they come in same size or should i look for better ones? have they upgraded, dated or whatever they do on these? what sizes nimh do they go to now? and what size should i look at? Cost? :illogical Thank you.... beetle	beetle (243)

There was a test done by PC User mag last year, the mAh (capacity rating) was found to be misleading on many. The best ones were the Dick Smith ones, rated at 2000 mAh. They were found to have better performance than the other 2300 mAh ones, which often came out only around 1800 mAh in the tests. The Consumers institute tests gave them about 1800 mAh useable, but they used a high discharge rate. Just don't believe the specified rating, most are overstated. Some Jaycar ones I have here are 2300 mAh and perform worse that the DSE 1700 mAh. DSE Catalogue S3153 for the 2000 mAh, pack of 4 for $23.98. WangaVegas branch has them in stock.... I have some of the older DSE 1700 mAh ones here, they do last well and are > 2 years old now.	godfather (25)

Energizer 2500s are easy to find at supermarkets but not that cheap. I've bought Maha Powerex 2000s before from Ian here ecobatteries.co.nz	PaulD (232)
448043	2006-04-20 23:03:00	Hi Beetle. Just thinking about your Ni-MH batteries not holding their charge. My camera has the facility to discharge the batteries virtually completely when the batteries only last for a short time after being charged. This apparently allows a full new charge, although I must admit to ever only having done this once - and that was just an experiment to see how long it would take to discharge and recharge. Others may have more experience with this function. Check your manual. Mine details how to do it way down at the back about page 120. Regards.	Scouse (83)

No two batteries are exactly the same in capacity, for instance one may be 1850 mAh, one may be 1920 mAh, yet all branded the same and from the same batch. When doing a complete discharge, the one that is exhausted first (the lower capacity one) will become "reverse polarised" by the remaining charged ones continuing to discharge through it. That quickly hastens the end of the useable life of that battery. So unless you have a matched set of batteries (highly unlikely unless you capacity tested and selected them yourself) its not always a good idea. This is why "battery packs" for high quality rechargeable devices cost so much. The cells are individually capacity matched and therefore give a much longer life in terms of years, compared to a random mix of unmatched cells.	godfather (25)
448045	2006-04-21 01:52:00	Thanks gf. Interesting. There is always someone out there with more knowledge of modern technology. When you mention "battery packs" are you referring to the expensive doubles purchased through camera shops?	Scouse (83)
448046	2006-04-21 05:56:00	This whole rechargeable battery thing is a minefield of conflicting opinions and scientific arguments. However all seem to agree on one thing that is: The cells need to be discharged to 1 volt per cell and then recharged otherwise the life of the cell is affected. I have used nimh batteries in my Fuji S7000 and so far I have gone three years with two sets of batteries and still going strong. I wait until the camera tells me that the batteries are nearly flat and then switch to the second set and put the discharged ones on charge. I think problems arise if you try and " top up " batteries when they are not fully discharged.	heaton (3697)

When I get my Fujis5600 I will get DSE Catalogue S3153 for the 2000 mAh, pack of 4 for $23.98. .If GF has tested,that will do me. Pity it doesn't have Image Stabiliser.	Cicero (40)

Batteries don't need an image stabiliser... oh, you mean the camera? Cut down on the Glenfiddich before breakfast and the shakes will gradually subside. Remember most cameras such as the S5600 may use about 2 mA even when "off" so the batteries will discharge at the rate of up to 50 mAh per day. Applies to my S602 anyway, so I just remove them when not using it for a while. The S3153 batteries are only $22.46 trade price at DSE, just consider that huge saving!	godfather (25)

I am so pleased you were able realise that batteries don;t have a lot to do with images. Am working on whisky problem,just thought it would be easier to use the stabiliser. Yes I thought it better to look into camera b4 buying,it seems some don't. The Fuji has a cut out system that precludes the problem you are having with discharge.	Cicero (40)
