what are the best batteries for a digital camera?
Q. I've tried duracell and energizer, and they both don't work for long. Digital cameras are indeed huge battery hogs. I even purchased rechargable batteries, and a energizer recharger for the batteries, and the batteries only last for 3 to 5 minutes, and then die. I just wanted to know what the best batteries for digital cameras are. I own a Samsung s630 6.0 mega pixels digital camera if that helps anything.

A. Digital cameras do, indeed, draw enormous amounts of power. The LCD screen without doubt is the biggest user of electricity. If your camera has a viewfinder that you can peep through instead of using the battery hog LCD screen, use it and get hours of extra use from your camera. Reduce amount of time that the LCD stays on in "review" mode after taking a picture. A few seconds is all that should be needed. I recommend turning it off completely! Don't waste your time reviewing the picture you just did while three more picture opportunities are happening in front of you, lost forever! Turn off the picture review and take more pictures! When it comes to batteries, "alkaline" chemistry batteries can't keep up with digital cameras, no matter… [cont.]

What kind of batteries are best for a model rocket launch controller?
Q. I'm planning on building a new model rocket launch controller, and I need help deciding what kind of batteries to use. The controller will have 150ft of 16 gauge wire going to the rocket and about three different buttons/ switches on the controller itself. What kind of batteries and voltage would I need to guarantee a proper launch every time? I'd rather not use a car battery and I've heard that 12v of AA batteries would not get the job done. Thanks for any help.

A. May I suggest that stranded (not solid) 18 AWG is better. Also you need a safety lock-out key and only one firing switch/button, not 3. Keep it simple. Keep it safe. 150 ft. of wire? You must be launching a big rocket. Better check to see that you are within Tripoli and NAR guidelines. 6 volts equals 4 AA batteries Why not use rechargeables? Better yet... why not invest in a small 12 volt rechargeable lantern battery? That will last 50 -100 launches without recharging. It will ensure enough power gets to your launch pad.

How long should batteries last in a Cannon 590is?
Q. I bought a Cannon 590is and am having a lousy time because of the battery life. Even with new alkaline batteries, they don't last to long. I returned the camera until I find out if this a common problem, and if a set of NiMH batteries will do the trick. Has any else had this problem? What woud be the best batteries to use?

A. Alkaline batteries are the worst type of battery to use because they don't hold enough charge to run a power hungry device such as a digital camera, for very long. Use them and you're just throwing money down the drain (or adding to landfill). Ni-MH recharegeable batteries are much more cost effective. You charge them, they drain...so you just recharge them again. Buying high capacity Ni-MH are best (something like 2500-2700mAh). They will need to be charged, used and recharged a few times before they reach their maximum charge capacity. Also, they do drain when not used (at the rate of up to 1/2 -1% per day). So, always make sure you charge them at least a day before (or on the day) that you need to use your camera. BTW...Using 2500… [cont.]

What are the best and cheapest batteries to use for a digital camera?
Q. I've just recently bought a digital camera. It's a SamSung Digimax S500. I've already gone through about 20 batteries in four days. (Both Energizer type and Duracell). What are some good batteries that last a long time in a digital camera? I love my camera and love taking pictures with it but get frustrated at the batteries always dying on me. Do you guys think I should invest in rechargeable batteries? Answers appreciated. Thanks!

A. If you went through that many batteries in four days you must be shooting thousands of shots a day. Or, there is something wrong with the camera, which is what I suspect. The best is not the cheapest. Buy the highest Mah you can find. I usually buy from an on-line source because they have the lowest prices. 10 minutes of time spent on the Internet will yield good results for you. If you want to lower your cost, buy rechargable batteries. Get at least two sets - one from the camera and a spare. Buy a quick charger and you can have a fresh set in less than an hour. Norm

What kind of rechargeable batteries are good for my camera?
Q. I have a Kodak Easyshare camera. I've been using the rechargeable battery back that came with it but that recently died. I'm using Ni-MH rechargeable batteries now and I'm wondering if they will clash with the docking station I put the camera on. Of course Kodak's website says to use their products... but is it safe to use another brand of battery with the docking station?
Asked by Andrew - Sat Apr 18 11:07:45 2009 - - 2 Answers - 0 Comments
A. If your camera is designed to use rechargeable NiMH batteries, any brand will do. You might consider using the newer low-discharge NiMH batteries. If you don't use your camera a lot, the low discharge batteries can sit around doing nothing for months and still have significant capacity. The older, and more common, NiMH batteries require charging every 2 to 4 weeks, even sitting around doing nothing.

How are batteries connected when you put them into a Walkman? And how can you figure out the total voltage?
Q. I think batteries are connected in series in a Walkman but I am not 100% possitive. Also, how can I find out the total voltage of two AA batteries that are each 1.5V? Is there a formula?

A. If batteries are side-by-side, the voltage stays the same (e.g., 1.5v), but if they're stacked end-to-end, the voltage adds up (e.g., 1.5 + 1.5=3v, etc.). Batteries are normally "stacked" into a Walkman, at least in my experience. :)

I sometimes do the same myself, but have found that I can take a far less number of pictures using the regular batteries. So I would suggest taking you an extra set if you plan to take a lot of pictures.

What happens to the batteries in hybrid cars when they reach their life-expectancy?

All of the battery recycling programs I've learned of relate to household and smaller (ie: cell phone and computer) rechargables.

In a press release, Toyota states, "Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, is recycled." Honda arranges for the collection of the battery and transfers it to a preferred recycler to follow their prescribed process: disassembling and sorting the materials; shredding the plastic material; recovering and processing the metal; and neutralizing the alkaline material before sending it to a landfill.

A. The best kind of rechargeable batteries for high drain electronic devices are NiMH(nickle metal hydride). They cost a little more then normal rechargeable buy they charge in 10-15 minutes. You do need a special charger as they can't use a regular battery charger. You can get them in different ratings and should try to find 2500 mAh or higher. I have a Canon A620 digital camera and with a freshly charged set of NiMH 2500 mAh batteries I get 300-400 pictures depending on how much I use the flash and sometimes more. Often I will fill my memory cards before the batteries need to recharged. Some info if your interested how they compare to traditional rechargeable batteries:

(1) === when battery V2 is flipped new voltage (V1+V2) new current (i) = [V1+V2] /R put the value of R from (1) i = [V1+V2] * I /[V1 - V2] >>> answer --- (2) now battery are in tune >> supportively coupled note >if you flip V1 then only direction of (i) will change not its magnitude === if V1 = 15 V, V2 = 5 V, I = 2 A then on flipping V2, you get i = (15+5)*2/[15 - 5] = 4 A typically current doubled for just chosen values

How are the batteries doing on the first generation, late 90's hybrids?
Q. I read the batteries were to be replaced in 8-10 years. I just don't want to buy a used Prius with a battery that's about to go dead on me. Thanks.

A. The warranty on the hybrid batteries are (depending on manufacturer) 8 years/80,000 miles or more, and for AT-PZEV models out to 10 years/150,000 miles. That's a full warranty, NOT pro-rated. However, hybrid battery replacements are very rare, in or out of warranty. Just because a warranty is up, doesn't mean that the item is bad or needs to be replaced! (when the bumper-to-bumper warranty ends at 3 years/36,000 miles, doesn't mean that the bumpers will fall off!) Yes, the first production hybrid on the road was the Toyota Prius, out in 1997 for the 1998 model year. However, the NHW10 model Prius (1998-2000 model years) was only sold for the Japanese market. Within Japan with the proper paperwork, there's a free trade-in for this… [cont.]

How long will batteries last in a baby swing?
Q. I need to purchase my daughter a baby swing and have tried to find the ones you can plug in, but have only found two and they are not pretty. She is having a girl. Do the battery operated ones use alot of batteries?
Asked by tulsanurse1 - Fri Jan 25 09:01:10 2008 - - 10 Answers - 0 Comments
A. We had to change the batteries on my son's swing about every other week. It really depends on how often you use it and how many other things it has (my son's had a mobile that spun around and birds that moved up and down, and played songs) so it took a lot. If you haven't looked yet, go to www.babiesrus.com and check out their selection.

How can I find out how many batteries it takes to power an electric engine?
Q. Is there any way to test it without buying all the types of batteries I can find? It is a small battery-powered engine. Like the ones in toys. I took it from an old CD-reader and I think it can reach up to 4000 rpm, since it is an 8X drive. Help! I tried a small AAA battery that I found lying around, but it didn't work. I guess I need more power. To William - There is no manual, there never was, I scavaged the "motor" (sry about that) from an old CD reader.
