Thanks, I found that - BP400 uses AA but not sure if it will take AA lithiums disposables, since these are OK in real cold weather.Doesn't the A1 have an optional battery holder-grip which will hold
either the proprietary batteries or AAAs?
IanI would like to use the A1 with AA batteries - trekking for 4 weeks
with no electricity in Himalayas. Anyone know of how to do this?
External battery pack and adaptor of some kind? Only batteries you
can get are AA ones.
Otherwise will have to get the 7Hi but since this is not much
cheaper than the A1 doesnt seem like a good idea.
Thanks

I'm not sure the 7Hi will solve your problem even if you did buy one, but, FWIW, you can get a 7Hi from Buy.com for $599 ($699 with $100 rebate).I would like to use the A1 with AA batteries - trekking for 4 weeks

Think you might be confusing disposable alkaline AAs and disposable lithium AAs. Lithium batteries will give you lots of power and hold up in the cold.You might be on a loser here. Non- rechargeable AA batteries do
not work with the 7xx, or at least not sufficiently well to be
useful. Indeed, the power characteristics of non-rechargeables
mean they are a poor match for (most? all?) digital cameras and
will fail after relatively few photographs ....
True, they are better than alkaline but I assume the object is to supplement supplies while travelling in the Himalayas and I wonder whether the lithium non-rechargeable AA's will be available there. The A1 battery pack uses 6 AA's so the problem with the 7xx that won't work off 4 alkalines is addressed. But, even so, will they last sufficiently long to be an advantage over carrying already charged rechargeables?Think you might be confusing disposable alkaline AAs and disposableYou might be on a loser here.

surprised if you rig up a pack that would be practicable. Solution
off the LCD, or a camera with minimal power requirements, or film.
- lots of Li-ion packs (eg DPS9000 or the Minolta one) and switch
How are you going to store your photos? If you are taking enough
pictures to flatten a few Li-ion packs you'll need a lot of memory.
Portable storage devices are battery powered too.
Hope for your sake that someone posts saying I'm talking rubbish.

No, they won't be available on the trek. Possibly in Kathmandu but I wouldn't count on it. They are readily available around here though.True, they (disposable lithiums) are better than alkaline but I assume
the object is to
supplement supplies while traveling in the Himalayas and I wonder
whether the lithium non-rechargeable AA's will be available there.
Well, as I understand it the A1 battery has a 1500 mAh capacity. I don't have any figures on the disposable lithiums but believe that they have 4-5 times that capacity. (Someone should dig up this data before I mislead people ;o)The A1 battery pack uses 6 AA's so the problem with the 7xx that

If you look carefully at the performance of solar chargers you will see that they take a long time to charge batteries. And you have to keep them pointed at the sun, not an easy thing to do while you're walking.How about taking along a solar charger? There is a variety of them
available, some of them quite light and compact.
PHDs can do quite a bit of downloading per charge. And the ones that use AAs can be powered with disposable lithium AAs.The need for some sort of storage bank is a very good tip. So
you'll need quite a few batteries.

So the decision, as I see it, hinges on the cost/weight of more A!
batteries versus using disposable lithiums.
If the standard A1 battery will deliver600 pictures per charge$15-18). The cost of the additional battery pack needs to be

Two thousand images is the equivalent of 55+ rolls of 36 exp.

I've been puzzled by the low capacity of such as the DPS9000 relative to NiMH yet the DPS9000 lasts so much longer. The answer is that their capacities are measured in different ways - or so I read somewhere. The link I gave ( http://www2.konicaminolta.jp/ ... ... dimage/dimage-a1/07_2_1.html )My better 'attempts'.
The larger solar charger at Steve's site will charge 4 AAs in 12 hours of sunlight. I live with solar. I've lived with solar for 14+ years. You don't get 12 hours of usable sunshine per day.Steve's Digicams has a review of a couple solar chargers here...How about taking along a solar charger? There is a variety of them
