Q:One of the battery pack to die, and a piece of it?

One of the batteries in parallel, this battery output capacity is twice as large, but other batteries can not output the same current, so no use.

Q:I heard it was possible to make a portable 12v source by combining 1 transistor battery and 2 double A's. The reason being is because I am wanting to test some 12v cold cathode lights that I bought for my car and test out different positions in the car before I hard wire them.Will this work? Are batteries DC?

What is a transistor battery? Two AAs will produce 3V. Obviously you need to get 9 more volts from somewhere.

Q:am looking to get a 360 but want to know if i have to buy a rechargeable battery pack for the controller. will i have to get two plug and play kits or is there an alternative. thanks

It comes with a battery holder for AAs. The rechargeable battery packs at sold separately on their own or with the Play and Charge or Quick Charger. You can also use regular or rechargeable AAs.

Q:I need to get a portable booster power pack to charge my boat battery in the off season and be available to jump on the lake in case of an emergency. What should I get?

The two uses you have, are not solved with a portable battery pack. Off season storage requires a maintainer type charger. That is something a jumper pack doesn't do. Almost any of the portable packs can jump a boat battery, however might I caution that electronic ignitions and computer controls do not like extraneous spark like sometimes you get when hooking up a jumper pack. So, I don't take the chance. I charge the battery, or use the maintainer charger and never jump my battery.

Q:I was wondering if xbox 360 controllers that come with a rechargeable battery pack have the same serial number as the one on the actual battery pack, because I think my little brother swapped my controller for his broken one but I can't really tell

simply put im afraid not sorry

Q:UPS battery pack maintenance time calculation?

Seeking time to maintain. S = C ÷ I = battery capacity ÷ output current 200 (ah) ÷ 39.0625 (A) = 5.12 (hours).

Q:How does UPS and battery pack fit?

C6KS you can access 40 12V65AH battery (20 series in parallel) the remaining 8 spare, full load 4800W about 6 hours.

Q:i have had a rechargable battery pack for my xbox 360 wireless controller for a few months and its the kind where u take the back of and but it on a charger and when its charging it turns red, and when its dsone it truns green, lately it become dead and i put it on and it does green insteadof red, it did tht for a few months but still charged it, now it barely charges it. what is wrong and wat do i do?

you simply need to replace the batteries. rechargeable batteries loose the ability to retain power. i also have rechargeable batteries for my xbox controllers and i would say batteries last about 5 months with regular usage.

Q:I have an Olympus Camera with a Model LI-42B Battery Pack.I haven't used my camera in a while so I charged the battery then pulled it out of the charger and put it on my desk. I don't remember how long it has been sitting thereI got it to try and use it and the sides are puffing out!It won't fit in the camera any more!I'm afriad that it will burst If it does, what does that mean?Is it dangerous?I put it in a plastic baggie just in case but I'm worried and PISSED that the GOOD battery that came with my camera has crapped out so soon.What does this mean?

Lithium ion batteries have been known to explode and to catch fire. It is one of the technology hurdles that has kept Toyota from upgrading the Prius to a plug-in hybrid with Li batteries. There have been cell phone and laptop battery explosions and explosions of larger batteries in military use that have caused catastrophic fires. These events usually occur while charging. I wouldn't keep the battery inside your house. I would call the camera manufacturer and complain about the defect. They will probably replace it because they will likely want your battery to identify the defect. In any case, if you are patient and search the internet every few months for the issue, eventually they will probably issue a recall as pressure from others builds. I had a similar issue with a Canon camera. By the time Canon caved in and agreed to fix everyone's cameras, similar models had shrunk to half the size and one third the cost. Oh, well. Still works fine.

Q:Basically, my desire is to power a fan off of a battery pack, while also having a solar panel fueling the battery. It also needs to be small enough to carry with me. Is this possible? Where might I find such a battery pack? I wouldn't mind using rechargeable AAs as opposed to a single battery.

A solar charger is designed to handle exactly the type of application that you are looking for. This will be available with solar panel vendors. The solar charger has separate connections for both the load as well as the battery. When solar power is available, it will supply power to the load, as well as charge the battery (charging voltage and current presettable as per battery capacity). When solar panel voltage goes below a preset level, the automatic switching circuit will enable the battery to take over. As far as your choice of battery is concerned, rechargable AAs will last only for a few minutes (depending on the power consumed by the fan). The best alternative normally used in portable power packs are sealed lead acid batteries which comes in standard power ratings like 6V 4 Ah (Ampere Hour), 12V 7.2 Ah etc. Choice of Solar Panel, Solar Charger and Battery depends on your fan's DC Voltage rating and the back up time (time you need to run the fan when solar power is not available)
