ralph w asked:


My digital cameras and my cellphone use Lithium Ion rechargeable batteries. I also have a set of four rechargeable AA NiMH batteries.

With the primary goal of preserving their battery lives, what is the proper way to use and store these batteries?

Is it always best to fully charge and then fully use/discharge them before recharging?

When not in use, is it preferable to keep them fully charged or discharged? Or does it not matter?

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? Thanks, curlycuejoyce.

There are many different batteries which are great for appliances. These batteries provide lots of power to the appliance that you need. When you are looking at which battery to use you will find that D batteries are perfect for products like torches and radios. You can test the battery performance of these batteries before you buy them in order to know if you have a battery that is in excellent condition.

By seeing to this matter early you will know if you need to buy more D batteries in another brand. This is a good idea as you avoid having to have more batteries than you need. You will be able to find the various D batteries that you want in any retail shop which sells batteries.

You will have to do some research to find which of the D batteries are made to last for longer periods of time. You will find advertisements and claims from various companies which will help you to select the D sized battery that you require. When you look at these differences you will have a better chance of judging which batteries are better for the appliance that you are planning to use it for.

In most cases the packaging on the D batteries will let you see which appliances will work best with these batteries. Sometimes you will also get to see rechargeable size D batteries too. This however is rare as the average D batteries are larger and thicker than your usual AA batteries. Now even though you will find it difficult to buy rechargeable batteries for the D class battery range the good news is that these batteries can last for quite a long time.

For the most part D batteries are sold in packs of 2. There are times when you will be able to buy packs of 4 or even 8 batteries. You will however need to look for these multiple battery packs in a variety of places. The general stores where you can find D batteries are in supermarkets, drug stores, camera shops, the internet and lots of other places.

You will have to be careful when you are choosing your D batteries as with all batteries these batteries have a certain shelf life. If you happen to buy a battery that seems to have run out quickly the chances are that you have somehow gotten hold of an old battery. To prevent this from happening you will need to select your D batteries from about the middle of the stack. You will then have a well working appliance with an excellent chance of lasting for a long time.

Pandora battery is a magic pattery for you video game.

With PSP Pandora Battery, you can unbrick & downgrade any version psp to version 1.5.

Pandora Battery Preparation

1. Make sure you have completed the “Memory Stick Preparation” first.

2. Plug the Memory Stick back in.

3. ***OPTIONAL *** Run the “Pandora’s Battery Creator” program on the PSP and press Triangle “/” to back up the contents of your battery’s flash into a file on you memory stick. The program will automatically exit. *Note:* This step is REQUIRED if you want to make this a normal battery again; otherwise it’s optional.

4. Run the “Pandora’s Battery Creator” program on the PSP. This prepares the battery. You will not be able to use it normally from now on unless you’ve taken the optional step above to revert after the fact (should be using a spare so you can keep it around anyways).

5. You now have a “Magic Memory Stick” and a “JigKick Battery”. Proceed to the next section to reflash your PSP.

Reflash your PSP

1. Remove the UMD, Battery, Memory Stick, and Power Cable from the bricked PSP.

2. Insert the Memory Stick (“Magic Memory Stick”) you prepared beforehand into the bricked PSP.

3. Insert the battery (“JigKick Battery”) you prepared beforehand into the PSP.

4. Boot the PSP. A menu will appear. Follow the onscreen instructions to reflash your PSP.

5. When the flashing process is complete, restart your PSP.

6. If all goes well, a blue screen will appear, telling you that your settings are corrupt, and to press circle to repair them. Do so now, rebooting your PSP if necessary.

7. You should now have a 1.50 PSP

Pandora Battery FAQ

?

Can this Pandora battery downgrade or unbrick any PSP?

Yes, you can unbrick any currently available PSP. This can also be used as a downgrader on a non-bricked PSP.

?

Can I restore my battery back to its normal state after this process?

Yes, you can if you’ve backed up the contents of your battery’s flash into a file on you memory stick; although, this defeats the purpose of having a battery ready for unbricking. That is why you are suggested a spare battery. Freeplay has found some very cheap batteries. Get them while they’re still cheap.

To revert a battery:

?



Take out normal battery

Power on PSP with AC adapter only

Once XMB comes up, re-insert Pandora battery

Run “Pandora Battery Maker” and press L+R to restore the ms0:/eeprom.bin to your battery



?

?

?

Can the Memory Stick be reformatted and reused?

Yes, however you will need to redo all of the steps in the “Preparations” section related to the memory stick for reuse as unbricker.

?

Does unbricking work on TA-082 motherboards?

It is known to work on all motherboard revisions. The reflasher will ask you to apply the patch. Press ‘X’ to do so.

?

The readme states that “The firmware in the Memory Stick is not a full 1.50 but a minimal subset.”; what’s that all about?

It simply means that the PSP will not act as a “complete” 1.5 PSP until you place your normal battery back in and restart.

?

Minimal subset? Can I install custom firmware?

As stated above, replace your normal battery and restart the PSP so that you’ve loaded the full 1.5 firmware from flash0 into memory; then you can do as you see fit.

?

The readme states that “The IDStorage cannot be totally restored, as there is no known way to regenerate it properly.”

They’re talking about if you bricked due to a corrupted idstorage. If nothing bad has ever happened to your idstorage, you can safely ignore this note.

?

Will this Pandora battery work on PSP slim?

There is speculation about this, At the moment, no one knows but we will specify here when possible.
