which technique is better in using normal AA cells (for a wall clock or any device that draws low current) ?

If there are 3 (AA cells) of 1.5V each and if the wall clock or any other device that draws low current radio transistor or telephone (loud music melody ringer) and because of any weak cell(s) the loud music melody ringer doesnt ring then, what would be better technique :
1) Replace all three cells
2) Replace the one that is the weakest (by testing from Digital Multimeter, the lowest DC volts cell would be replaced).

thanks

If a remote stops working I rotate the batteries in place to clean the small contact areas. That usually keeps it going for a while longer. With multiples I do use a tester, but usually find that are all weak so I replace all. Replacing just one will mean you have to do it more often unless that one is considerably weaker and the others aren’t too bad.

Regular AA batteries are always 1.5V for voltage, but rechargeable AA batteries that I have seen are either 1.2V or 1.25V. Why is that? Also what (harm) does the slightly lower voltage do to my devices such as digital cameras, remote controls, wall clocks etc?

So they produce different voltages based on the characteristics of the chemical reaction that produces electricity. Zinc-carbon battery – Also known as a standard carbon battery, zinc-carbon chemistry is used in all inexpensive AA, C and D dry-cell batteries. The electrodes are zinc and carbon, with an acidic paste between them that serves as the electrolyte. Alkaline battery – Alkaline chemistry is used in common Duracell and Energizer batteries, the electrodes are zinc and manganese-oxide, with an alkaline electrolyte. Lithium-iodide battery – Lithium-iodide chemistry is used in pacemakers and hearing aides because of their long life. Lead-acid battery – Lead-acid chemistry is used in automobiles, the electrodes are made of lead and lead-oxide with a strong acidic electrolyte (rechargeable). Nickel-cadmium battery – The electrodes are nickel-hydroxide and cadmium, with potassium-hydroxide as the electrolyte (rechargeable). Nickel-metal hydride battery – This battery is rapidly replacing nickel-cadmium because it does not suffer from the memory effect that nickel-cadmiums do (rechargeable). Lithium-ion battery – With a very good power-to-weight ratio, this is often found in high-end laptop computers and cell phones (rechargeable). Zinc-air battery – This battery is lightweight and rechargeable. Zinc-mercury oxide battery – This is often used in hearing-aids. Silver-zinc battery – This is used in aeronautical applications because the power-to-weight ratio is good.

So, my parents are giving me up to $500 dollars (not including paint for the walls ) to re-do my room. Here’s the furniture I’m planning to buy.. :

Full Length Mirror
Floor Lamp
Wall Clock or Digital Clock
I’m also gonna personalize my room by making a collage(s) using Artist Painting Canvas’.Im gonna make 4 of those and arrange it like this:

My Walls: One Wall will be Dark Purple and the other 3 Walls will be really, really LIGHT purple..

My Bedding:

The bedding only comes with the Pillow Shams & Comforter. So, I will be buying purple sheets..

iNeed more ideas for my room… pleaseeee! help me…..iM not sure if iCan order things online, but just send me the links and ill try to ask my parents if iCan.. (:

OH! i got these wooden letters (still need to paint it) and i was gonna put it above the collages..

OH! (again…) its my birthday in september and i usually get $200-300. so, im gonna add that for my room.. but if i dont need the extra money, ill spend it on shopping…. lol.. hahahah..
in the words/phrases that describe me,

i mean like… what i like and stuff..
oh also, i cant afford much deco b-cuz most of my money will go to the new furniture.

be careful using purple. it can quickly become a color that is sort of sickening when you have to live in it for too long.
(im 14 and my room was purple for a while. I quickly realized it was NOT what i was looking for.)

But anyway, good choice making one wall an accent wall. (the dark purple). just keep in mind that that is going to be the attention grabber in the room. Put decor or seating that keeps the person looking in the room’s attention on the wall for more than 2 seconds.

Good idea with the bed. The loft feel is very in right now and it saves space by giving you storage underneath. That is something you will need even more as u get older, trust me.

However, since a desk is included with the bed, I wouldn’t buy the writing desk, though it is cute and i looked at it myself also. Two desks will make the room confusing and might make people double take in the wrong ways.

You dont need much money for this makeover. The most expensive thing will be the bed. $800 is way too much. I redid mine in much less when I replaced my desk, my dresser, night stand, and added a bookcase, plus wall murals.

As for decor, you have the right idea. Making things is an easy way to ensure that you are getting exactly what you want.
For example: A clear vase with black stones at the bottom and purple and white fake flowers coming up from them.

ALSO: just know that the "you" that you are now, will change a lot through junior high. Make sure that before you dive into this, you have a room/color palette that lends itself to other ideas later. The color not so much, because painting is easy, but make sure that the furniture you choose is something that is subject to change just in case the color palette does.

Hope it helps !

I want to know if there’s a place that i can download for free that has a nice looking digital clock to set as BG. But i would still like to keep my BG that I have on now.

this is what I’m talking about. http://i421.photobucket.com/albums/pp291/PaulFrisky/wall.png

Here is the clock you want: it is a Sidebar Gadget, which means that it can be used in Windows Vista or 7. You can also browse the gallery for other gadgets for your desktop if you want.

what do you think of the start of my story?
i’m 16 and have no professional writing experience at all….so here goes

The rain poured heavily from the sky blanketed in dark clouds. Peering through the small circular window covered in layers of fog, it was difficult to see beyond the glass. Having leared a small patch on the glass with my hand, a faint image of what was going on outside became visible. The storm was furious. The heavy clouds and blinding flashes of lightning followed by turbulent crashes of thunder filled the sky above the small town. Despite the temper of the raging
storm, I felt no hint of concern. When the weather got like this, it never lasted for long periods of time. I let out a soft sigh and glanced over to the digital alarm clock that sat on a wooden desk that sat against the wall left of me. It was 7:00 in the morning, and I assumed that my parents would be waking soon, so I decided to go downstairs for breakfast, although I didn’t feel like eating much. I turned away from my window and slowly started making my way through my messy and dim lighted, but stumbled over a pair of black converse shoes tossed messily onto the carpeted floor. I let out a groan as I hit the floor. I cursed a little under my breath as I stood back up and continued on my way out, almost tripping over an old and empty pizza box. "I really need throw that away!" I said aloud to myself. And it was true…the box has been in there for a long while now, and it’s starting to smell funny. I picked the box up off the floor and walked over to the door and then I let out another sigh and left the room. I walked across the hallway over to the stair case and fought my worst instincts to slide down the railing.

There is too much describing. Your tense changes often. It’s average

don’t like the truth? give me a TD, idgaf. because you can’t write
