Questions & Answers
Question : Can a 12 volt 10 amp Charger and a Nascar mobile power pack booster wreck a vehicle?
My Sister has a 2006 Toyota Tundra V6. Theirs a problems with the battery or altenator. Anyway I wanted to move it and I was impatient. I had the 12 volt 10 amp slow charger on it and I quickly hooked up the nascar mobile power pack charger on it but it was dead anyway but somehow it took power from the slow charger and it was enough to get it started. I was quick about it. Anyway a couple lights show up on the dash, one is a Maintenance Service repair light and the other one is a warning light. What I'm worried about is, can this damage the computers, or something, is it possible I could have or is that just telling me the batterys bad or altenator. Please let me know, so I don't have to worry about any damage. Anyone.Ok, I didn't turn the ignition on until I had them both hooked up quickly, then once the truck started, I quickly unhooked the booster first followed by the charger. Is that what you mean? Should everything be ok and like you say it might just be a bad battery or alternator maybe?
Answer:
Did you connect the cables of the booster with the ignition in the ON position? It IS possible you could damage the electronics this way. However if the truck battery was dead, you could just have a charging system problem showing up...

Question : Astro Wireless 5.8 RX Mix Amp Help!?
Well , I am planning to buy the Astro A40 headset, and do not know which Mix Amp to buy. Here is the wireless: http://www.astrogaming.com/products/detail/108/A40-Wireless-System/Now, the problem is, that I do not have any idea how the battery system works! There are two parts of hardware a receiver and a sender, does the receiver use batteries, or a usb charger, or both? And does the sender use batteries? If so, if i were to order the rechargeable battery pack, what will the battery pack work for the receiver or the sender? I have no idea, and am completely confused right now, it would be great if someone could clear this up.Also... Can i use the wirelesss system on my Ipod? Can i plug in the optical cable to my TV instead of the Xbox and have the same sound quality?here is my first question reworded:Where do i put the batteries in the astro 40 wireless system, and how do the rechargeable batteries work?

Question : Hello. I am tryng to charge two lead acid battery packs, but can't. Help?
The multimeter read about 1.4 volts each when I got them, and they won't go over 3 volts when I try to charge them. What could be the problem? I connected the charger wires directly to the two battery terminals like I do when charging other batteries. I just bought them two days ago, and I really need for them to work. I tried a 7+ volt 600 mA phone charger, and a 4.5 volt, 1 amp phone charger. Thank you for your time. Below is what was printed on the battery packs.Sheng Yang SY640. SLA VRLA. 6 volts. 4 Ah. Constant voltage charge: Cycle use: 7.25-7.45 volts, standby use: 6.8-6.9 volts, initial current: less than 2.4 amps.
Answer:
You need 9 Volts to charge these batteries.You have to have three volts highre than the rated nominal voltage output..

Question : Need help getting the right charger for my Ni-cd battery pack! Home built Project!?
I have put together a 4.8v battery pack for a project I am working on. it consists of 20 1.2v 1200mah cells in 5 groups of 4. if I have done my math correctly, the total current output on this should be 24,000 mah or 24 amp hours. since the voltage is 4.8v and when fully charged the volt meter reads 5.2v across the pos and neg terminals. I need to come up with a charger for this battery pack.I figured on basing it on a 8 hour charge schedule having the charger put out a total of 6400 mah or 6.4 amps. my problem is that I don't know how much higher to have the voltage output on the charger. I read somewhere that for each cell that is 1.2v the charger should put out 1.5v to .1.6v is this true or is there another approach?
Answer:
Uh... a few things wrong here. If you connect four 1.2V, 1200 mAh cells in series that stack will give you 4.8 volts, 1200 mAh. Five of the above connected in parallel will give you 4.8 volts, 6000 mAh. Not 24,000. You do not get to multiply the mAh rating by the total number of cells in the entire pack unless they are all simply connected in parallel - and then there is no voltage increase. If that is confusing, think about it this way. One of your cells provides 1.44 watt-hours (1.2V x 1.2 Ah) of energy. 20 of them can therefore provide 20 x 1.44 = 28.8 Wh. Using my figures above, 4.8V x 6 Ah indeed equals 28.8 Wh. Using your figures you'd have 4.8 x 24 = 115.2 Wh. That would be a conservation of energy violation. It can't happen. To charge your 6 Ah pack at the 8-hour rate would then need a charger that can supply a little less than an amp. HOWEVER - I should warn you that series-parallel connections like this are a bad idea. The cells are always different enough from each other that if you try to charge the sets in parallel, some will be overcharged and some undercharged. If you need 4.8V at 6 Ah, you should get some 6 Ah cells, connect 4 of them in series, and be done with it. Failing that you should isolate the series sets and charge them individually. Using standard old NiCd "dumb charger" techniques, yes, 1.5V/cell is about right. Be sure to take them off charge when they are fully charged or you will overcharge them, likely causing voltage depression - often mistaken for NiCd "memory".

Question : How long should I charge my SLA battery?
I have a 12v sealed lead acid battery and my battery charger is a 3 amp one, unsure if it's regulated or not so I don't know how long to leave the battery charging. It's a battery from a car jump starter pack
Answer:
Batteries are power tanks.The total run time for the tank is expressed in volts & amp hours.To determine charge time (hours), you divide the amp hours of the battery by the power of the charger (because the battery and charger voltages match).Your standard car battery is between 40 and 120 amp hours. This is dependent on weight and size. A large diesel truck will have a pair of 12 volts, or a really big one for instance. We'll assume you have a 50 amp battery to do the math here, but you may have to adjust for your situation... If you have a 50 amp battery, it takes 17 hours with your charger...Hours = (battery amp hours)/(charger amps) + 1 hour for finishing.h = 50/3 + 117.6 hours or roughly 17 hours 40 minutes.To charge faster, buy a larger AMPERAGE charger....so for a 20 amp charger:50 amp hour battery / 20 amp charger + 1 hour for finishing = 3.5 hours

Question : Could I use the spare 12v connector on my computer power supply to power a R/C battery charger?
I have a 7.2v Battery Pack and a car charger with 12v DC input, using clips that go directly to the battery terminals. Could I use the spare 12v connector on the psu to power the charger? The charger has a 6.5 Amp replaceable fuse in it.The computer is custom. I realised there is an old psu here as well, and I think it might be safer. This spare psu has a table on it with voltages and amps. The +12v says 15 amps, and the -12v says 0.8 amps. ( I know I can turn it on by shorting the green and blacks wires, looked it up on wikipedia)The computer is custom. I realised there is an old psu here as well, and I think it might be safer.

Answer:
If it fits, yes, it'll work. The same plug is used for a lot of things -- most notably, guitar amplifiers.

Question : How much voltage should a brand new 24volt battery pack get?
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.I metered the voltage at 28 plus volts at the highest reading before the green light came on. It never got up to 29 volts and the battery itself never got hot, only slightly warm. With charger disconnected the battery now reads just over 27 volts.......so I think everything seems to be normal at this point.
Answer:
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.

Question : Has anyone found an external battery charger that'll work for the Vita?
I have an iCruise IMP1000, which is an awesome external battery pack, but it only outputs at 1 amp. The Vita requires 1.5 amps, so it doesn't take a charge from the battery. Has anyone found an external battery pack that'll work? I want a good one for spring break, because I plan on using my Vita a lot on the 2 day-long bus ride :)
Answer:
I wouldn't risk putting an unofficial charger on the vita since its expensive, use only sony ones

Question : 1 hour NiCd Batter Charger, is it SAFE and will it LAST ?? (on cordless drill etc)?
I notice more and more cordless drill that use the good-old NiCd Battery Packs have 1 hour charger.Check out the following links:http://www.toolbarn.com/product/panasonic/EY503B7658/ orhttp://www.mytoolstore.com/dewalt/dew09-02.htmlAs far as I know the recommended charge is 10% of the specified Amp capacity over 15 hours.My question is, is this safe, and will the battery last?Or do they have any special circuit to handle high current charge, and/or automatic shut off when full?
Answer:
They are as safe as any electronic device and will last just like any other electronic device. You can charge a NiCad battery at what is called the C rate (specified amp capacity) as long as you can sense and state of the battery and shut the charge off when the battery is full. The C rate is the 1 hour current rate. Damage to the battery would be from heat boiling the electrolytic out of the vents in the battery. How long the battery will last depends more on how it is used rather than how it is charged. I used to maintain a fleet of hand-held radios with fast chargers. The batteries typically lasted over 3 years. NiCad's should be good for 1,000 charge/discharge cycles and these batteries were getting that plus a little. You can charge a NiCad battery indefinitely at 1/10 C rate. The current at this rate doesn't get the battery hot enough to hurt it. A 1 hour charger would have to have the circuitry to shut off the fast charge and switch to the slow charge rate when the battery reached a certain point. They typicall have a heat sensor, which helps detect bad batteries, and a voltage sensor to determine state of charge. I have used fast chargers for over 30 years with good results. The popularity of the fast chargers is due to the fact that people who use the tools for work can't wait for 15 hours to charge the battery. Even if they had an extra set, it still wouldn't work. You would need at least 5 or 6 batteries and chargers if you were charging them at 1/10 C just to keep a charged battery in your drill. By charging the battery in 1 hour, you can keep going with just 2 batteries.
