Digital Camera Battery?

Has anyone tried the Energizer Lithium AA Battery for their digital camera. Did they really last longer than the regular AA battery. Just want to know before I buy, they are rather expensive. What about the rechargable batteries, any thoughts on them? I'm tired of my camera eating other batteries. I have a Canon A540. Thanks.

Lithium is a great battery, but costly. I recomend you look for the highest capacity nickel metal hydride rechargable batteries you can find with a charger. I use to own the A540, but upgraded to the A710is. Both are nice cameras. I use Duracell 2650 MAH batteries in them, and they last very well. Your A540 has a decent view finder on it. It's better than the view finder on the A710is.....honest. Because of that, you can use the view finder with relative ease as opposed to the LCD, which eats batteries, and, washes out under bright sunlight. (lots of digital do that). The downside of the view findes is 1) no diopter, and 2) it's only about 80% as accurate as your LCD screen. If those items are unimportant to you, then use your view finder as much as possible. When I had the A540, I was a little disappointed with how it tended to wash out on bright sunny days. My advice to you is switch to the "P" mode, then set the ISO to 100. That will help.

i haven't tried the lithium, but in my experience the rechargeables work longer and are less expensive in the long run.

The disposable lithium AAs will definitely last longer, but they are not a good choice in the long run except for emergencies. As you have already figured out, rechargeable NiMH AA (not NiCads!) are the best solution for your battery needs. Not only will they last longer, but after three or four recharges, they will have not only paid for the batteries, but also the cost of the recharger.

Make sure you get batteries at least 2500 mAh (milliamp hours) in capacity or better. This rating measures how much power is stored by the battery and allows some comparison between manufacturers (although some manufacturers really stretch the truth on these figures! I've had 1600 mAh batteries outlast "2500" from some cheap brands!).

Equally important to the batteries is the charger. A good one will charge the battery properly and fill it to its maximum energy capacity; a poor one will shut off too early or worse, too late, like a gas tank hose that shuts off before your tank is full or overfills and overflows. This latter possibility is bad, as overcharging kills rechargeable AAs.

To help you out, I've included a link below to a good AA recharger. I've ordered from these folks before, so hopefully nothing has changed with them.

the only choice is to buy rechargeables
2500 or 2700 !!!!!

MHZ's are so cheap now that I carry three extra sets in my gadget bag. You can find very cheap 1800 mah to 2000 mah batteries for under $5.00 a 4 pack. The 2500 and 2800 mah batts will cost from $7.00 a 4 pack and up. Harbor Freight, for example, sells 2000 mah batts in 4 packs for $3.99 and a very good charger (that will charge AAA, AA, C, D and 9 volt batts.) for $9.95. The trick I use is to keep the plastic pack that they come in and only open the one end of it to get the batts out. Then after recharging them I put them back in the package and that is a good way to put them in my camera bag.
