Q: I bought a Canon VIXIA HF R300 Camcorder a few months ago, and I noticed a message saying to change the battery pack almost as soon as I turned it on. I just decided to wait and see what that meant, since I didn't know why it would need it; I had literally just gotten the camera. Now when I turn on the video camera it says that message every time, and when I go to look at the videos I've recorded it pops up there too. When I'm recording the battery drains REALLY fast. Why is it doing this?How do I fix it?: Are you charging the battery according to the instructions in the manual? If so, you have a defective battery.

Q: I am using My Canon 6D to take photography for an event running from 7-12. Will my battery die before this or will I be good with one battery the whole night?: Canon 6d Battery Life

Q: A 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 15 m/s and then throws the battery at 7 m/s in the same direction. What's the resulting increase in his speed after each throw?____________________m/s speed increase after discarding camera____________________m/s speed increase after discarding battery: His initial momentum is taken as zero. Momentum of thrown camera is 1 kg x 15 m/s 15 kgm/s his mass after that is 90+10 100 kg. He acquires the momentum of the camera, so 15 100ΔV ΔV 15/100 0.15 m/s Momentum of battery is 10x7 70 kgm/s again he gains this momentum, and his mass is now 90 kg 70 90ΔV ΔV 70/90 0.778 m/s

Q: I have an old remote control air plane rechargeable battery I want to use for something else. The problem is I need it 9.6V and the two packs of 5 cells is 6V each. I want to combine the two 6V into an 8 cell 9.6V but I can't seem to split them apart. Currently I'm discharging them through the old airplane motor that they came with. First off, should I be messing with them. If so, is running them through a motor a good way to discharge them, and finally how should I go about separating them so I can recombine them?: Those 6V battery pack was packed with hard glue and welded joints. Separating them is not an easy task as you though without any proper tool. Besides, most old old rechargeable battery pack 50% inside the cells were dried out or leakage or shorted due to aging. Not much chance to rebuild them into a workable 9.6V pack.

Q: I need some advice on upgrading the electrical power on my .46 Hobbico Nexstar.Here's the situation: the battery I'm using right now is a Futaba 4 cell 4.8v that's about 3 years old. But it's kind of on its last legs- I charged it throughout the night, but it was dead when I got to the field. I still was able to quik-charge it up to 5.4 volts, and got 3 short flights in without any trouble. Now I charged it fully, and the reading is 5.52. Some people say it's the battery- others say it's the at-home charger (3 years old). Either way, I want to be sure that I'm not going to have one of those instances where the plane loses electrical power in midair and you can only watch helplessly as it keeps on going. What kind of battery should I go with? Charger?: Get two new battery packs, a good quality charger, AND a battery cycler. The problem with most rechargables is 'partial charge memory'. NiCad or NiMH battery packs usually never really get totally discharged after a series of flying and begin to develop a short charge or partial charge memory. Useful output diminishes over time and the packs require CYCLING. Cycling is a regimen of totally discharging and recharging 3X. DO NOT TOTALLY DISCARGE LiPo packs, you'll kill them. Only do this to NiCad and NiMH. You can make a cheap discharger from a few 6vdc or 12vdc automotive turnsignal bulbs soldered to gether in parallel with a pack connector. Just plug it in and the bulbs will draw down all the power in your packs before recharging fully with your new peak charger. Hobbico has a nice little unit called a Field Charger. Good Luck!

Q: I have a Wii and xbox 360. I have 4 controllers for both consoles, although not always used at the same time. Should I get the rechargeable battery packs for each controller ( a little pricey) or just some AA Energizer rechargeable batteries with the charger.: It is a tough call. You can buy the rechargeable AA cells and use them in the other devices, but have to keep track of them. The proprietary batteries will just be there

Q: I dropped my battery pack and i am wondering if that is the reason why i am not able to turn on my pc. thank you in advance.: it depends on how hard you dropped it. batteries for laptops are a LOT harder than they seem. Are you sure it's not charging or plugged in? Do you have the cord set up right? is there a crack anywhere on the battery? If the battery is damaged then prepare to pay for a new one. There not cheap. (unless you think 100 dollars is cheap)

Q: i want to buy something to recharge my controller: I've just tried it. Yes, you MUST use the rechargeable battery pack that comes with the plug 'n play kit, otherwise, no dice.

Q: can anyone help in designing a quad-bike chassis driven by a 2HP electric motor powered by 48V battery pack??? this is for my final year engineering project. The battery pack would be 4 12V pack or 8 6V packs.: drop a note to these guys, and check out Gorilla Vehicles

Q: I have a 7.2v battery, and after I charge it , I use my battery volt tester, and it says the battery has 8.3v, and after the battery pack is almost dead, it says it has 7.3v. What does this mean? There's nothing wrong with my battery volt tester.: The load that the tester applies on the battery is very small(a few micro-Amps) so even if the battery is dead for the device that operates with it,it will be ok for the tester. When a rechargeable battery is fully charged its voltage is 10% higher then the nominal voltage(only for rechargeable batteries). If you want to test the battery use a small load on it(a 12V/2W) bulb light and with this load on test it with the voltmeter! good luck!
