Hi,

Just wondering if anyone knows if it is possible to connect a series of AA batteries to power the FZ cameras? I'm travelling to Africa next year and it will be difficult to charge batteries regularly. I already have 4 Li-ion batteries but would like to be able to carry more sets (of AA's) and have the ability to use my 15 minute charger for these batteries.

Thanks

the FZ's battery is rated at 7.2v nominal. ordinary alkaline AA cells are 1.5v each. you can't get to 7.2 using 1.5 v cells. theoretically, you COULD connect 6 NiMH AA's(whichi believe are rated at 1.2v each)in series, which would give you about 7.2v, but AA's in series would be a very bulky, heavy set-up, and you probably couldn't recharge them any more easily than the regular FZ battery.

Consider the digipower dps9000 7.2v li-ion.$40 at Ritz Camera. It attaches to the tripod hole and plugs into the fz5ac/dc jack. Comes with ac charger as well as a cig lighter charger. Here it is onnikon 5700.For more info see http://www.imaging-resource.com/ACCS...00/DPS9000.HTM

I am pretty sure the camera is safe to 8.4 volts, as that is what the charger is and if you use the AC cable that is what you get ...and someone reported if you check the voltage of a fully charged battery it is 8.4 volts.

The FZ30's Power Source is "DC 8.4 V" as per operating instructions page 137.

If you get a 6 - AA battery holder from ratshack, and the proper power cord, you can use that for throw-aways. I've tested my FZ30 with everything from 9 VDC down to 5.5 VDC and it worked well with no problems. I've got my own homemade pack ready to go for less than $5.00! The hardest part of that is to get the correct power plug. Tom

To solve this autonomy problem i saw on nomatica.com a product called PM85-22.

It s a small belt battery. Price is 58E. I ve not tested it and i am curious too. Could be you can check.

oh just saw that UK pag eof nomatica gives no real information on the product. icopy paste you what i saw on french page (was in FZ30 accessories):

Capacité de la batterie : 22 Wh ; Voltage : 11V / 8.4 V / 5 V ; Indicateur d'usure de la batterie : 4 niveaux ; Courant de charge : 1500 mA ; Temps de charge pour une batterie complètement déchargée : 1.5 heures environ (maximum 2 heures) ; Poids (weight): 180g, Taille : 58.5 x 24 x 82 mm ; Pas d'effet de mémoire

A simple 6 slot AA battery holder may not be enough.

A year ago when I had spare time to waste on these things, I put together 6 NMh AA cells, some wire, and the appropriate plug and tried it on my FZ10. It worked fine for reviewing photos, but the camera shut down when I switched to any of the photo taking modes before it had finished extending the lens.

I measured the power at the plug and it dropped under 5V while driving the lens. I also measured the resistance in my wiring: it was negligible. So I concluded that 6 AA cells just couldn't deliver enough juice and I abandoned the project.

For the FZ30, things may be different, since the lens zoom is not powered. However, for all others, I expect you'll need more oomph than 6 AA cells can deliver.

PS: If anyone knows where to buy the Digipower dps9000 in Australia, I'm quite interested.

I think the original post was looking for a way of using disposable alkaline batteries, but that aside, you could always use a 8 cell holder with a dummy cell in one position to get the higher voltage for using NiCads. I was testing with NiMh cells and a FZ30. That combo worked well with fresh charged batteries, but I didn't try a run time test on it. A dummy cell can be made by wrapping a dead alky cell in aluminum foil. Don't do it with a fresh one!
