How do you turn a C Cell battery into an AC adapter?
Answer #1: Here’s the dilemma, I have a toy that uses 4 C Cell 1.5v hp pavilion dv7 batteries, hp pavilion dm3 battery (6v total). The toy doesn’t move so I’d like to get an AC adapter to plug it into a wall socket. The problem is that there is no external plug in the thing, so I would like to remove all the batteries and insert an ac adapter that can connect through the C cell battery compartment so that it can be used in the wall outlet. Here are the specs:
DC 6V ~- 3 W
Answer #2: I’m not sure if you already HAVE an adapter because you said you would “like to GET an AC adapter…..” And the last thing you typed APPEARS to be the spec of an AC adapter you already HAVE.
Anyway, if you DO have one with that spec, it should be easy to connect it to your toy, and since it is 6V @ 3W, it should be OK for most any toy using C cells. (regarding power requirements)
IF the adapter you HAVE has a round DC COAXIAL PLUG , you can remove the plug and with a voltmeter, determine the polarity of the remaining wires. (or determine the + by noting which conductor was connected to the center pin of the plug)
Then, inside the toy’s battery compartment, find the wires leading from the hp pavilion dv9000 battery, hp probook 4311s battery contacts going to the toy’s electrical circuits or motor. You need to determine the polarity of these two wires, and can easily do so by determining which wire is connected to a positive battery contant and which was to a negative. (ignore any wires interconnecting BETWEEN battery contacts, as they will not be used in your setup)
Now, solder the positive wire from the adapter to the positive wire (or the contact itself), feeding the toy, and neg. to neg. also.
That’s all there is to it !
Now, just in case the spec you wrote was for the TOY and not an ADAPTER you have, then you will need to GET one with a 6 V output and 3 W or greater. Many places sell them.
Here is one possible problem you may encounter: You did not say the NATURE of the toy, and if it involves electronics which need “clean” power, without “ripple” as in the case of some toys which may include audio circuits, etc., then your AC adapter will have to be a FILTERED and / or REGULATED type or you may experience HUM or other problems. (batteries provide clean DC voltage, and some AC adapters do not)
What is a Sony Button Cell Battery?
What this article is talking about is a technical low down on the inner workings of the famous button cell battery and in respects to manufacturers, it will be discussing on the Sony vgp-bps9 battery, sony vgp-bps8 battery button cell battery and how it sets itself apart in the market of batteries, which presumably is a huge market. Also called the watch battery, the coin cell is actually a small form factor of a battery that was originally designed to be in watches. However, in times, the use of this button cell battery was expanded to very compact and small electronic devices like pocket calculators, small digital recorders and even hearing aids.
The good thing about the batteries is that they often sport a very long half life within the gadget, meaning that it can last a very long time and things can run. Their voltage can range from 1.5 all the way to 3 volts, and are often made of zinc or lithium with cathodes within the matrix of the battery often being made up of manganese dioxide, carbon monoflouride or materials like silver oxide and some derivatives of mercury. The common physical incarnation for these types of dell vostro 1310 batteries, dell vostro 1710 battery often have the appearance of a small silver button with markings on the surface to designate the manufacturer and of course the voltage that it can give out. They are sold for a relative cheap price, and depending on the materials used, can cost from $10 onwards in the local hardware stores.
When purchasing a button cell battery, there is really nothing else you can do when it comes to choice as from one manufacturer to another, they have to conform to industry standards and build the battery down to specifics. While the only thing you can think about is the materials used and the reputation of reliability, and when it comes down to this, the brand of Panasonic is one that stands out among the rest. Well it is not the best brand out there, it sure is one of the best, sharing the pedestal with many other well known manufacturers. Panasonic also has commercially available rechargeable variants of these batteries and this is really useful when it comes to maintaining the long life of some of gadgets.
Also, watch batteries are utilized in a degree of devices that have a very slow drain rate which means they get replaced only once in either a few months or even a few years, so using rechargeable batteries do not really have a practical place within watches at all. There are some commercial places that do sell these rechargeable variants’, and as of last year, their numbers have increased and their presence on the market is now larger than it was a few years ago. These are made to replace the CR lithium type batteries (dell latitude e6400 battery, dell latitude e6500 battery) in many devices that have an unusually high electric consumption rate. These are some of the things that you need to know about Panasonic button cell batteries and their applications. There are so many easy ways to get these batteries, and more likely than not, you can find them in your local hardware stores. Whether you have a laser pointer, glucometer, security tokens or spotting scopes, the button cell battery is the right one for you.
