Default 7Hi battery life

I understand that using standard alkaline batteries, the battery life can be limited. Are there any alternatives to using standard alkaline batteries? Thanks.

Limited is not the word :shock: How about 15-20 min out of a pair of brand new Energizers. Get some NiMH and call it a day.

I had the chance to use these 2100mAh batteries over the holiday and definetly recommend them:

Absolutely, get NiMH batteries and a good charger designed for NiMH's. The 2100 mAh batteries are the latest and greatest, highly recommended. Get at least 2 sets, and if you shoot a lot, get 3 or 4 sets.

On average, using 1800mAh NiMH's, I get about 90 shots per set, no flash, no autofocus and NO LCD (only EVF).

Is this over several days? because that's what I get over days/week period. The camera uses the batteries even when it's off.

Using the same settings with AF in the studio I get regularly over 350 shots/set with a microdrive and Quest1600mAh/GP1700mAh in an hour period. I use this time to download the microdrive to the MindStor and change the batteries (before the low battery warning show up!)... Something must be wrong with your batteries or charger (I use mostly the Rayovac 1hr)... Hopefully it's not the camera.

Try a brand new set of battery and squeeze the shutter down... if you don't get several hundred shots at the highest jpegs in a short period, something is wrong with your camera (or the charger)!

NHL,

That's basically continuous shooting on a set of freshly charged batteries over about a two to three hour period, so the camera is always on (or sleeping).

I would love to be able to get 300+ photos on a set of batteries. I have no idea what the norm is. Everything I have read is that the D7's consume batteries like there is no tomorrow, so I was not unhappy with my 90 or so shots per set.

It's not the batteries, as I have 5 or 6 sets, all numbered and matched, and I get consistant life from all. I also don't think it's the charger. I have 3 or 4 chargers, and all, also seem to deliver similar battery life.

I can live with 90 shots per set of batteries, it the $%*&#@ autofocus that *&%$#@ me off. Perhaps Minolta should patent it as the AutoNotFocus system :-).

I think you need to send your camera in:

I can assure you that 300+ in 1hr is easily attainable, and I have done it all the time (with a microdrive)! 90 shots is what I usually get in a week period... for a day trip I can usually fill the whole microdrive on only two sets of 1600/1700mAh.

Your AF seems out of specs as well. It's quite quick and accurate with mine since the upgrade, but not like the 7i/hi...

NHL,

I am using a 7Hi and the max number of shots I can get is 50 pictures with auto everything and 50% flash. Is that normal? Also I find that the batteries last only for 2 hours max when being used on and off during the day. I consume 3 sets of batteries for a days outing.

I am using the Sanyo charger with 1850, 1800 and 2000 mAh batteries from GP.

Also, I find that except for the Sanyo batteries, the GP batteries don't last that long even for the bigger capacity 2000 series. Should I get a fast charger from GP or send the camera back for checking?

Thanks
