- Q:I'd go thru maybe 6 a year of AA. I'd go thru 4 of AAA. What is the biggest multi-pack I should buy?
- A good alkaline battery has a shelf life of about 7 years. Still, there's no reason to buy this many. A 12 pack should be about the right quantity. A 2 year supply is ample. I'm sure you can buy more if you run short for any reason.
- Q:I am looking for a glossy gold rechargeable battery pack for my xbox 360 controller. I am buying a whole set up for my controller that's gold and glossy and chrome and stuff.
- that's going to be supper hard to find i recommend just buying the double a batteries that they sell in the store
- Q:i need voltages. there are four terminals where the battery goes, im sure one of them is a ground. i just need like a diagram for how i can wire up batteries to it. thanks for any help
- get okorder
- Q:But works when the regular batteries are used, or works when using the other rechargeable batter pack. Why?
- humm. okorder
- Q:How long will a 8.4V 7-cell NiMh mini battery pack or a 9.4v battery last in my m4? And how long should i charge it for. What is a smart charger?
- confident! The electrify is off. i bought D batteries for lamps. The batteries final for 4 hour interior the lamps or fan. while the lamp is going out, I positioned them interior the freezer in one day. an analogous batteries have lasted yet another 4 hours. i'm repeating this to work out what share cases i will recharge the batteries. The Fuji batteries say that they could explode if recharged. Or could they simply prefer you to maintain procuring batteries. The Duracell alkaline battery tells you to no longer fee, put in hearth or connect improperly or the battery could desire to explode. the cheap CVS alkaline battery additionally says do no longer set up backwards, fee or put in hearth or could explode. base line is a small a million.5 volt battery could be recharged a minimum of as quickly as by making use of putting in freezer. i does no longer positioned then in longer than in one day. I even have been making use of lamps for terribly very nearly a wee. They take 2 d batteries that final 4 hours. I even have 4 gadgets of batteries that I even have usernames then recharged. No issues yet. Dry the batteries earlier making use of. Act at your guy or woman danger.
- 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
- No, that is a waste of funds. do no longer stack your 360 in a shelf with out air circulate. An intercooler won't shop you from the RROD, neither will acceptable storage and utilization. each so often, that is inevitable. Microsoft will restoration it, and shop you the cost of the fan.
- Q:I have a 12v monitor and a 12v spy camera could I hook them up to a 12v battery pack with a dc splitter, or would there be issues. But I also have a 8v spy camera, is there a easy way to hook it up to a 9v battery?
- You need a 12 v pack with enough current to operate them both for some period of time. So you need to know how much current they use in a given hour. They should spec their power usage in watts. So you divide that by 12. That will give you their current draw for one hour. Then, if you want them to operate, say for 8 hours, you need a battery pack with an output of a little more than their total current drain over that time. Say they draw 1 watt each, so that is 16 watts over 8 hours. 16 w/12 v is 1.33 amp/hours. So, in this case, you would want a battery pack capable of at least 1.5 amp/hours. The 8 volt unit is much the same. You need to know it's current drain per hour and then you need a 9 v battery with a high enough amp/hour output to run it for how long it will be on. A simple small 9 v battery won't have enough power to even turn it on, much less, run it for any time at all. You would be better off to use the 12 v supply (if big enough) to run all 3 and just use a current limiting resistor in the 8 v line.
- Q:I want to put 4 AA NiCad or NimH batteries in a holder (Radio Shack 270-383) and connect two set of positive and negative leads. One to a DC Power Jack (Radio Shack 274-1565) for when the battery pack needs to be recharged and the other to a DC Power Plug (Radio Shack 274-1567) for when I want to use their power. Will this work?
- It will work fine. What you're describing is a simple parallel circuit. As long as the positive and negative leads don't touch, you should do just fine. One word of caution, you should limit the charge current with either a resistor or a current regulator. NiCds and NimHs should be charged at 1/10 their amp/hour capacity for 10 to 14 hours. Example: A 2200 mAh AA cell should get 220 ma for about 12 hours. Also keep in mind that this pack will only give you about 4.8 volts whereas 4 alkaline AAs will give you 6 volts.
- Q:I recently purchased a NiMH battery pack with a Futaba J connector. I also bought a charger, but it does not have the right connector. The charger does however come with an adapter to alligator clips and a red and black wire. I looked on my batter and noticed that there was only a black and red wire actually in the Futaba connector. I was wondering if it would work to connect two pins to my alligator clips, and then connect them to the battery. It is for a school project so any help would be greatly appreciated. Thanks!
- You can, yes. The only real danger would be connecting the battery backwards. There is also a better chance of a false peak (charger thinks the battery is charged, but it is not quite), but that poses no risks. Just be careful to hook it up correctly and you should be fine.
- Q:I know that NiMH batteries self-discharge over time, but mine are discharging in just a matter of hours. I am using them in a RC airplane. They are 9.6V 650mah AAA packs. I charge them up just as they should be and they put out full power when I test them in my plane. I go to the gym for a couple hours and stop by the flying field on the way home, but when I plug the battery in the motor on the airplane immediately goes to cut-off.An interesting note: If I hold the arming button down to keep the motor going, eventually it will work itself up to putting out enough power to do some low powered flight and will last the duration over normal flight time for the airplane
- The battery pack is new to you, but it could have been on the shelf in the store or a warehouse for a very long time, easily a couple of years. A single bad cell can ruin a battery pack. 1) One of the cells might have gone bad and can't hold much charge, so it depletes quickly during discharge. The available battery voltage then is 9.6 - 1.2 8.4 volts. As current flows through the bad cell the current reverse-charges the cell, and the available voltage drops to 8.4 - 1.2 7.2 volts. 2) When a motor starts it requires a high current, and this drops the voltage out of the battery due to the internal resistance of the battery. If one cell is bad then the internal resistance is very high. Once the motor is running the required current is less, so the internal resistance of the battery is less, and the battery is able to maintain an adequate voltage. Factories do not test the cells to match their discharge cycles. This can happen to any battery. Car batteries, sealed lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries. extra : This is a huge problem for any large power-storage system, from solar-cell systems to hospitals and server farms. They use large battery banks to give them ride-over time until they can get their gasoline/diesel/natgas generators running. Monitoring each cell in a battery requires special electronics and in the past was not worth the trouble due to the cost. There are now electronic designs that will do this monitoring, but it's not going to be done for cheap RC battery packs.
