Q:65 18650 lithium battery how to spell 12V battery pack?

Composed of 12V lithium battery pack, according to the individual lithium battery voltage, you can use three, or four, assuming that four, after the series can be composed of a lithium battery string.

Q:I took apart a dead Roomba Battery pack to see if I could replace a few cells and found that one of the battery's polarity had switched from negative to positive. I've never seen this. Luckily it was at a very low charge. Do you know how to reverse polarity on a NiMH battery so I can reuse it? Or am I out of luck?

Q:I just purchased a 2004 honda civic hybrid that had set for 4-6 months. It needed a transmission. I got a transmission for it and got it going but now it sets p1433 battery deterioration. Ive only driven it once for about 3 miles. If i continue to drive it will it recharge itself? Just curious if its just low because of it setting for so long.

idk buddy it would make sense that it wud since the alternator recharges the battery in the engine it may be set up so that it also recharges the p1433 too. i personally dont think the hybrids are better because u need parts that are rare if they go bad

Q:i have an old laptop with only 1 battery pack in the back. How do i make it work?

looks like your charger as long gone down this happened to my dell for no reason in any rejoice with it stopped charging i theory it became as quickly as as quickly as the battery and purchased a clean one, it became out to be the charger. purely suitable fortune have been given a substitute ment from OKorder for 20 quid purchase it now

Q:Hello,I would like to know if anyone is aware of a solar power panel, such as GoalZero, that can charge a digital cameras battery pack. I have a Canon SLR and would like a panel to not only charge my AAA's batteries, Droid, and GPS, but most imprtantly the battery pack for my SLR.I haven't been able to find an adapter to charge a battery pack, as most solar panels utilize USB ports. The battery pack that comes with the camera must be installed into a device that plugs into the wall outlet.I would appreciate your help.Thank you all in advance.

Forget Solar charging while backpacking. even a 5W panel which is 12 by 24 will take over half the day to do the charging. Unless you want to sit all day and charge, extra batts are the way to go.

Q:I have a 8.2v battery pack (supposed to be 7.2v but its always around 8.5 when charged) that runs a circuit. The circuit has motors in it that turn on and off. I have a wireless cmos camera that taps into the same battery pack, the camera needs 8v. The unit works fine until the motors turn on then the camera shuts off for the duration of the motors being on. I had a similar problem before but it was downstream in the circuit after a voltage regulator, I stuck a large capacitor after the voltage regulator and it solved this problem. I tried putting a capacitor on the camera and it didnt seem to help much. Do I need a voltage regulator and a larger battery pack to do this or is there another way ? I'm thinking its not so much the current that is the problem but the reduction in voltage coming from the battery under heavy load, but I might be wrong. thanks !

Get a 9-12 v battery, and run the motor directly from the battery (insure that the motor is rated for the higher voltage) then run the camera off a parallel wired reducing voltage regulator. I fly high powered electric R/C planes and we use a similar scheme to power the receivers and servos.

Q:Can you please give me a price on a Battery Pack UN34AS1-T for my laptop.

very confusing point. try searching over google or bing. that will help!

Q:I have the controller for it but it didn't come with the battery pack. There is one listed on OKorder for $40 and I heard there is a non-official pack that will work. Any help would be great.

Depending on the State and city you live in there are still game stores (other than gamestop and EB) that carry a wide variety of used merchandise for all platforms. This includes games, systems and all accessories. Try looking up stores online or in the yellowpages.

Q:I took out the extra battery pack and tried working it with the battery slot inside it. I've fully charged the battery but the camera just won't turn on anymore! Is there something I'm doing wrong? Please Help !

Your description doesn't quite make sense. You camera only has one battery slot, the only way you can use an extra battery pack at the same time is with a battery grip. Are you you using a BG-E5 battery grip? If so, are you saying you removed the grip, put a charged battery in the camera and it does not work? Does it work if you put the grip back on the camera? Have you tried contacting Canon at 1-800-OK-CANON (1-800-652-2666)?

Q:I foolishly burned out 2 green LEDs already since I provided too much voltage. The 2 green LEDs I need to light up have a forward voltage of 3.2 volts each. The battery pack has 3 AA rechargeable batteries, for a total of 3.6 V(1.2 V per battery). If I remove one battery, the LEDs won't light up at all. How can I reduce the voltage so it doesn't burn out my LEDs, do I need to use a resistor or can I use something else? If I need resistors, what kind of resistors should I use?

You don't, you use a resistor to limit the current going to the LED, the voltage taking care of itself.
