/>intro: Make a Battery for a Rechargeable Mouse
My dad gave me his old wireless keyboard and mouse because his old mouse wouldn't hold a charge for very long. I have been looking into a wireless keyboard and
mouse for my notebook but prices are not in my range as of right now ha. So i took his and began looking into the manual for it when i saw that it could also run on 3AAA
batterys. Yeah, that could be easier to do, but i don't want to go and buy batterys every time the mouse runs out (which is why i want rechargeable, duhh) so i have 2
options. 1-get rechargeable batterys and link them together so they could be recharged on the dock or 2-find something else that could be used as a battery.
step 1: prep
take out the battery case and remove the battery, then remove batterys
Image Notes
1. take the batterys out and use the case
2. party wound dont ask
Image Notes
1. just like i thought, 3AAA
/>Image Notes
1. old connectors, dont need them
step 2: getting the new battery
i decided to use a ipod mini battery that i had laying around from all the ipod parts that i have. i cut the black and red wires, extended them, and then wrapped them
around the appropriate metal tab.
Image Notes
1. neg

2. pos
Image Notes
1. added wires to the end of the battery for length
2. ipod mini battery (the battery comes with 3 wires:red, black, and white. you dont
need the white)
3. just twisted the wires on, the lazy way
/>step 3: finishing up
place the battery into the existing case and close up. Finally, test the mouse!
<br>
i let the battery run out just to test if it recharges. the following day,l i put it on the cradle for a few secs and it worked. i'll update to give the full battery length.
Image Notes
1. an oh so perfect fit, it just snaps into place
Image Notes
1. charge dock
2. power cord goes here
Image Notes
/>1. lights on, its charging!!

Great Work! I have this mouse and it desperately needs new battery's.
How did you crack open the battery compartment?

Just a small cover under the battery, just pry it off and glue it on afterwards

Question, does anyone know if there is rechargeable button cell batteries? because i have a bluetooth headset that needs new rechargeables, and if there is
i will even make and instructable on it

i think so

how well does it work charge cuz it looks like the original batteries say ni-mh and the ipod mini battery says li-ion? I thought they charged differently

If you didn't want people to ask, why did you include the word party and use your left hand in the shot? you do have a right hand, don't you? And if not, I'm
sorry.

Interesting to use an IPod battery, but as you show in your photos this mouse uses 3 AAA NiMH rechargeable batteries. The same as you would buy from
any store. So why not simply replace the batteries with matching NiMH rechargeables. I know its not as adventurous though.

This is obscenely dangerous. Nickel-cadmium and nickel-metal-hydride batteries can be "dumb" charged, you just put the right voltage across them, and
they'll accept current until they're full. Leaving them on the charger once they're full heats them up a little and may shorten their lifespan a little, but it doesn't
do any immediate damage. A very low current ("trickle") charge is common, and good practice.
Lithium-ion and lithium-polymer batteries on the hand, must be "smart" charged. The bulk charge is delivered with a current-limited supply, but when the
open-terminal voltage reaches a certain point, charge current must be carefully monitored, and when current drops to a certain point, the charging supply
must be disconnected.
Continued charging past the safe termination point will cause metallic lithium to plate-out on the electrodes, which will then short out the battery, causing it to
melt or explode which the industry euphemistically terms "venting with flame". A trickle-charger is also known as a detonator if you stick a lithium battery on
it.
The Gyropoint is designed for nickel metal hydride batteries, and thus the charger lacks the specialized logic required for lithium. This instructable is likely to
burn your house down. Please educate yourself about lithium battery charging before playing with this energy-dense, lightweight, and fickle chemistry.

Agreed, you can see on the picture if you look closely that the Ipod batt does say "Li-ion"
"white wire, you don't need it" Well, indeed you do. Because of the more volatile nature of of Li-Ion, the individual cells are charged individually. I'm

not sure about the i-pod battery, but notebook batteries and Li-Poly(a cousin of Li-Ion) batteries have individual wires coming from the junction between
cells for this purpose Look near the bottom of this link for what i'm
talking about.
In short, do NOT use Lithium-based batteries unless you know what you're doing. I mean REALLY KNOW what you're doing.

:-\ yours uses a pack? mine uses 2 AA batterys (witch i use rechargables) they last me 2 months of basic use and 1 month of gaming :-)

well if im correct, AA puts out 1.5 volts and AAA is around 1 volt. ill have to check though
!Andrew_Modder! says:
Aug 25, 2007. 1:10 PM REPLY
no AAA, AA, D, C, = 1.5 and 9 volt = 9 and rechargables are 1.2 but my rechargable AA batterys still work
kawouter says:

AAA, AA, C & D batteries - if NOT rechargable - put out 1.5 volts. Recargable batteries put out 1.2 volts.
The amount of charge they can hold depends of the size and of the cemicals inside the battery. NiMH batteries usually hold a larger amount of load
than NiCd batteries of the same size.

AA, AAA, D, and C batteries all put out 1.5V. They just hold different amounts of charge.
uberchoob says:
Dec 4, 2007. 9:43 AM REPLY
BAH!! Different rechargable battery companies sometimes vary in volts Energizer has AA AND AAA batteries in BOTH 1.2 and 1.5 volts
Likewise, mah varies from model to model Energizer has 2500mah models and 2200mah models in both AA and AAA
End of discussion?

rechargeable batterys are 1.2v and alkaline batterys are 1.5v.
uberchoob says:

Dec 4, 2007. 1:42 PM REPLY
Like I said, it varies if you can prove me wrong, please do!! =)
!Andrew_Modder! says:
Dec 4, 2007. 4:51 PM REPLY
1.5 Volt Alkaline AA-AAA
1.5 Volt Lithium Ion AA-AAA (this is non rechargeable!)
1.2 Volt Rechargeable NiMH AA-AAA
1.2 Volt Rechargeable NiCad AA-AAA
3.7 Volt Lithium Polymer (you must buy from a custom place.) AA-AAA, Sub C, any.
-currently there arent any chemistries out that are 1.5 and rechargeable :-( Only 1.2, 3.7, 12 volt, (basic, single cell), there are more,
but these are the main ones.

Of course there are 1.5 volt rechargeable batteries.
GRANDCELL makes a range of them.
This project need to be removed. As someone else said, LI Batts require a their specific charger. This project can kill you and burn
down your house.
DO NOT ATTEMPT TO BUILD It.

/>1.5 volt rechargable AA's
though, i dunno if the batteries are "rechargable" or if it's just the circuit.
see for basic circuit.
