Q: I recently bought a MacBook Pro 17in. and one of my school requirements says that I need an extra battery pack. I know that the MacBook's battery is built into the laptop, so you can't just get an extra and change them when you want.I have been looking around for an external battery pack or some sort of external battery so that i don't need to use a wall outlet during class.I have recently found a product called HyperMac. Has anyone heard of HyperMac and if they're safe or reliable or anything?If not, does anyone know of a good external battery for the MacBook Pro?Thanks!: call or take it to an Apple keep or Apple self sustaining provider centre. Your battery has a a million twelve months/3 hundred cycle 80% charge guarantee and you are able to desire to have the capacity to get a clean one if yours is below 80% of recent skill at complete charge. Battery existence relies upon on the kind you utilize the gadget. if your backlighting is grew to become up, you will get much less existence. in case you're watching video clips or doing FPS gaming, you will get lots shorter battery existence by means of fact your are working the GPU at close to a hundred% complete time.

Q: DUE TONIGHT PLEASE HELPA 90 kg astronaut floating out in space is carrying a 1.0 kg TV camera and a 10 kg battery pack. He's drifting toward his ship but, in order to get back faster, he hurls the camera out into space (away from the space ship) at 18 m/s and then throws the battery at 11 m/s in the same direction. What's the resulting increase in his speed after each throw?speed increase after discarding camera.?speed increase after discarding battery?: The key here is to remember that momentum is conserved. Momentum is mass times velocity. Are you sure you've got the masses right, surely the TV camera is heavier than the battery pack? Since (relative to each other), neither astronaut, nor camera nor battery is moving, the total momentum can be taken to be zero. So after throwing the camera away, the total momentum should be zero m/s. That means the astronaut should have equal momentum in magnitude, but opposite in direction, to the camera. Let's take the direction the camera was thrown in to be negative. Then the momentum of the camera after it is released is (1.0 kg)(-18 m/s) -18 kg m/s. So the momentum after discarding the camera must be 18 kg m/s. Dividing by the mass of the astronaut (plus battery pack, as he's still got it at this point), which is 100 kg, gives an increase in speed of 0.18 m/s. Now we do the same thing with the battery pack. Since, relative to each other, neither are moving, we can say that the total momentum before releasing it is zero, so the total momentum after releasing it must be zero also. The momentum of the battery pack, since it is thrown in the negative direction also, is (10 kg)(-11 m/s) -110 kg m/s. Therefore the total momentum of the astronaut must increase by 110 kg m/s also, and dividing by the mass of the astronaut (90 kg) gives a speed increase of 1.22 m/s.

Q: I just got my xbox 360 2 weeks ago and i cant use it without plugging it in (it has chargable battery pack) i charge it for LONG periods of time but when i unplug it and play the most it lasts is 2 minutes: i accually have the same issue with my conntroller, but thats probually because Iv had mine for 2 years instead of 2 weeks lol sorry man

Q: I need buy a new battery for my computer and my moms computer but I keep seeing 6 cell or 12 cell.and 4400mAh and 5200mAh. I need to know what batteries would be correct for our computers. The computers are Compaq Presario 3700 and Toshiba Satellite L645-S4102 pretty old laptops but they still have some fight. so please help out.Websites to find cheap batteries would help too. Really anything would help. Thanks: many times speaking, confident, it would routinely equate to double battery existence. Do observe regardless of the incontrovertible fact that, that the 12 cellular is heavily extra desirable, and so your laptop won't lay flat (the battery will act as a sort of prop-up).

Q: I have an electric scooter with a brand new 24 volt battery pack. When I charge the battery the voltage gets as high as 28 volts or more. I bought a brand new charger that has a 1.8 amp output rating. The charger light stays red while charging and should shut off when it turns green. So far I have not let the charger charge until the green light comes on. I am concerned that I am overcharging the battery. Right now my multimeter reads 28.48 volts. Is this normal? Thanks in advance.: 28 1/2 volts doesn't worry me; many sealed lead acid batteries charge to more than 2.3 volts per cell. At 29 volts I'd get concerned and at 30 volts I'd call it quits. However, the real issue is whether the batteries are getting hot. If they are just slightly warm they are still converting the energy to chemistry, but if they develop a fever (call it above 110 F) they are just turning the charge into heat they are fully charged.

Q: Everytime I try to plug my switchless Nyko intercooler into my 360 and try to on it, it doesnt work, I put all the correct plugs in. Also the battery pack it comes with confuses me, do I use the the packs it comes with which has no batteries and put it into my controller or do I put the 360 controller battery pack in there, any answers regarding these two questions will be appreciated especially answers regarding how to use these two and any other background info: Alright battery pack is same as regular battery input. Just push it in until it clicks or at least stays in the controller I have the battery pack thing too. Always charge them overnight. Inter cooler which I also have just put into the back of your xbox there are pegs on the inter cooler that clip into some of the holes in the back of your Xbox. Then make sure the plug in for power is in its specific spot. Then turn on your xbox and that fans should start to spin and the Xbox will make more noice.

Q: I run a Batteryman Deck. One of my main cards to get monsters from the graveyard is Portable Battery Pack. That card's effect is susceptible to Giant Trap Hole, however. What would happen if I were to chain Trap Stun to Giant Trap Hole? Would it negate the special summon of the Batteryman monsters or would it simply negate the secondary effect? The secondary effect is that if it's destroyed, the monsters summoned are destroyed, and if they're destroyed it's destroyed?Please stick to actual rulings and try to avoid opinions about how batterymen suck or anything like that.Thanks!: Trap stun negates all other trap effects for the turn. If your trap stun is chain link 3 then any other traps activated before it are negated because portable battery pack hasn't resolved yet.

Q: . I could not pick it up for 6 weeks and it sat idle, Just received it and the IMA battery level is at only 5 lines near the bottom of the gauge. I a still not able to register it for another week.have i damaged the IMA battery?. Also does the IMA battery charge while car is idling?. I tried that for an hour, with no change on the gauge. I did take a chance and drove it around the block once, and the top left gauge indicated it was charging, but no change on the IMA side(it was about 1/2 mile. Also note while sitting the weather averaged 27-35 degrees for almost the whole month.: hold the rpm at 3000 for 5 minutes and the battery gauge should show full charge, a 13 year old ima battery is most likely going to be bad, they usually last 6-8 years.

Q: Do you guys know where I can find a Xbox 360 Controller Battery Pack? Not the Rechargeable Pack.The ones where you put batteries in it. lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;lt;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^I live in CANADA!: unfortunately the only way you can get these is by purchasing a new controller, the battery compartments aren't sold separately anywhere

Q: 1)I have an R/C plane with a battery pack that is 9.6V250mAIm looking for backup battery packs, my question is, is this an okay battery to buy it looks the same but I know little about electronics2)If it sounds like i can buy the other battery, what voltage/mA can i go up too, Because I want the longest flight time /capacity: 1.) I believe that you got the units wrong. mA is a unit of current, mAh is a unit of energy. Don't get the two confused. 2.) If you want to increase the duration of your plane, then what you need is a battery with a higher mAh capacity. mAh dictates the amount of energy the battery has. Thus the more energy the battery has(measured in mAh), the longer lasting your plane would be. Get a battery with a higher mAh and then your plane will last longer. However there is one thing that you must consider. Not that many battery companies post the mAh rating of the battery on the actual battery itself. Thus you may want to visit the companies website to find the exact battery specifications you need. 3.) The voltage rating of the battery must remain the same, or you risk damaging the internal electronics inside the circuit. Unless of course the circuit has a voltage regulator(Nowadays almost everyone uses a regulator). If the battery that you purchase is within tolerance I would def. use it as well. I would get any battery that has a higher maH rating and any voltage upto 10.6V. 4.) The current rating does not matter for the battery.
