Panel Battery What kind of solar panel is necessary for a fully charged battery 3.5V 400mA?
I wonder how many watts should be the solar panel to fully charge the battery to full sun with some 5.5 kWh/m2/day of solar irradiance. Thanks, I would to charge in 6 to 8 hours
Its battery capacity is about 3.5 volts * 0.4 amp-hour = 1.4 watt-hours. Assuming an efficiency of 66% charged, the charger consume 1.4/0.66 = 2.12 watt-hours to charge at you like 6-8 hours, so you need a panel that provides between 2.12 / 8 = 0.265W and 2.12 / 6 = 0.35W. You could buy a panel that is valued at around that power, but if you really want to estimate the surface 5.5kWh/m2/day = 687.5 W / m 2 (assuming 8 hours of daylight intense) Current solar panels have an efficiency of 15%, so the area = Power / Radiation / efficiency = = 0.0034 0.35/687.5/0.15 m2 = 34 cm2 (approx. 6×6 cm) is a bit small, but is also a small battery.
Panel Usb Charger Will this solar USB charger charge my iPod Touch 2nd gen?
Solar panel : 0.4W
# Ac input: AC100V-240V
# Output Voltage 5.5V DC
# Convert efficiency: over 18%
# Max output current: DC 500mA
# High capacity build in polymer battery: 2600mAh
Sorry, no.
An iPod Touch needs 500 mA of charging current, even a 300 mA charger won’t work (I tried it myself, it doesn’t).
Assuming you could actually get 0.4 W out of that panel at 5 volts, that’s only 80 mA of current. But small panels tend to have optimistic specifications, so the actual current you get could be just 20 mA.
You would look for a panel that says 5 volt output, 500 mA or more. Such a panel would likely be 1 foot square, or 1 foot by 2 feet.
Charger More buick regal 91 wontstay started for more than five seconds sounded like the battery put charger on,did nothing
what can i do? it wants to start but then dies again.
There are 2 important items you need for the car to run, fuel and spark. if you trace these two things back, you should find what is missing.
Good luck.
Car Battery What would cause a car battery to gradually discharge over 2-3 days?
Basically I can always start the engine using my portable battery booster, and the battery does recharge as I drive my car since I can restart the engine normally after a short while (depending on how much I drove). However the battery does gradually discharge, and I must use the booster again if I wait more than 3-4 days.
Would this be a battery problem, or something else like the alternator (although the battery does recharge, and the car runs well once boosted)?
Thank you.
This is most likely one of two things: either the battery is failing (how old is it?), or you have something that’s drawing off of it over that time, maybe a trunk light or glovebox light, something like that. As batteries age, their ability to hold a charge declines.
Based on your description, it’s not the alternator, it provides power to run the car and charge the battery, and it sounds like it’s doing both of those things.
If the battery is a few years old, I’d replace it and go from there.
I spoke earlier about the importance of properly packaging your item for shipping. When it comes to fragile items is even more critical than the appropriate packing material is used to protect the item.
1. At a minimum material, proper packaging, corrugated cardboard box back into the outer casing fragile bubble around the item, and packing peanuts to fill any empty space inside the box. You must use a box larger than the size of the game after the bubble wrap. For example, if the object is 10 "x 4" x 4 "after the bubble wrap, look for a box of at least 14 "x8" x8 "to allow 2" of peanuts on all sides to protect the object of everything you can get outside the box.
2. For articles dishes, using the small bubble wrap or foam laminates to separate each piece. Place the foam roller or bubble down with the bubbles to the plate, place the dish on the wrapper, use another adjustment layer above the plate, set the next course, and continue until about 8 dishes. Once you have protected the dishes thus use large bubble wrap once around the stack.
3. Glasses, cups and service parts should be wrapped individually with plastic large bubbles. This helps protect the larger pieces are broken during transport.
4. On very fragile items, double boxing is recommended. Follow the instructions in item 1 above. Then find the largest box that fits it the first box and leave space for you to add 2 more inches of peanuts. Build the bottom of the big box, add 2 "of peanuts, insert the smaller box, fill the gap space with peanuts, and seal the box.
Remember to use carton sealing tape for all shipping boxes. The use of tape, adhesive tape, adhesive tape or is unacceptable for shipping. The adhesive tape and literally melt off of the packages in hot processing facilities. Duct tape does not save the sealed cardboard boxes.

Marine Battery Charger 1996 225 Mercury Outboard No Spark?
OK, so I let the boat sit for way too long…now working to get it going again…
Both deep cell marine batteries dead, won’t hold charge…Using a charger, tried to get the engine started…engine cranks, but no love.
With a friend’s help, checked the spark plugs and no spark…Checked kill-switch and it was depressed by the doohickey, all good there…wondering though if that kill switch maybe controls spark and it went south during the “resting period”?
Also checked the fuse on the powerhead electric box (?) and it looked fine.
Looking for suggestions of things I can check to see why plugs aren’t getting juice.
Thanks!
Your instinct is right in that most kill switches interrupt the flow of electricity to the spark plugs. Are you certain that there is no power to the plugs? If that is the case the ignition coils for the plugs may have been compromised but for all of them to be damaged seems unlikely. The first thing to check is to make sure that the kill switch is properly hooked up to the ignition wiring that runs up to the remote from the engine and that the wiring is in good shape.
Another option is that the alternator is not providing enough electricity to the engine to properly manage the power demands. This may also have something to do with your batteries not being able to maintain a charge.
The batteries themselves may be compromised and unable to provide the necessary amps/voltage at the start. I would consider replacing the batteries and make sure that they meet the manufacturer’s recommendation for CCAs. Hope this helps at least give you some more things to check before running up a big service bill.

We went to a race to go to school or work, and ugh, the bike will not start! How frustrating. Here are a few basis points check with quickly return to the road.
First: The basic questions:
Did you have on the brake? (Some scooters demand the right to be brake pressed)
It's kill-switch off?
It is the key to everything the way? (I know it sounds silly, but as a repair shop foreman / Scooters me here all the time when the power switch is sticky and does not light the whole way. The owners are embarrassed when I make sure that the lighting is completely forward and the bike starts immediately. Always working for the mechanic, right?)
Second: Is to work? Try start it. , When a tee shot, do not give the bike gas (May be as floods). Try to implement, is 5-10 times. If this does not work, give it some gas and try again.
Third: Check the fuse near the battery. Most boxes fuse near the battery fuse replacement if the original is released. Check the fuse first. It only takes a minute. If the blow, replaced by another session in the case.
Fourth: Jump Start-it - The scooters are not like cars. A battery scooter can be so dead, there is nothing you can do to begin, except to charge the battery or replace it. So, meanwhile, go to it. Now, a word of warning. This little scooter batteries can burn quickly, and if you decide to go, just put the cables in some seconds to get started quickly and disconnect. If you put in cables for 5-15 minutes, can destroy the battery. These batteries are not scooter can handle amps to put in car batteries. If you want to buy a charger net, get a 2 amp charger.
Fifth: Take your boat starting liquid (you know, you bought when you bought the scooter - scooter each owner must have an ADC) and spray a little liquid in the UNI Air Filter that are in your carburetor. They try again. If it starts, it continues to operate the throttle. Keep your fluid Start with you in the seat up Do you find this happens with your scooter.
These steps should get most of the scooters and go on the road. If these do not work, it may be something more serious, but at least we have bases and saved us a repair bill for something that was stupid or easy to correct.
Happy Riding.

Import 1A Trickle Car Battery How long?
I have a car battery to import died sitting in my car. I use my car for about three months and a week ago, I realized that the anti-theft light on the radio stops blinking. I have a 1A charger net on the battery, meaning more for motorcycle batteries. I a 24-hour timer switch lamp where you can connect the charger net and were manipulated in the hands of recharging the battery throwing 15 minutes. The time is not a problem in the battery. We'll probably use the car again in a month when the weather is very bad. My question is how long it takes normally the battery if it is charged continuously from 0 to 100% and the total number of hours per day is recommended that you charge the battery slowly bring up 100% in a month? Remember, I'll be over in 15 minutes jets to be easy on the battery and an opportunity to "rest" between the 15 strokes per minute. Thank you
You do not have to give it a rest between charges with a trickle charger for about 24 hours would be good. Remember that if you do not get all the way charged when the car is running at full load. Do you want to avoid that is fully charged, then let the charge go zero. When the battery is completely taken by the entire spectrum of cargo, which tends to warp the lead plates in the battery This causes a short and kill your battery.

Like the human body needs a heart to work, cars also depend on their indispensable part of the batteries that make them work. There are many other parties in a human body and a heart that can make these two bodies of work but incomplete, because the requirements are. A minor problem can become a major problem at the right time not putting you at risk for life, both in the case of a car or a human being.
In the words verbatim, function more important to a car battery is supplying power to the engine and check the ignition system of an automobile. Its main function is to provide power to the starter motor vehicle. In general, battery is known as SLI (starting, lightning and ignition) engine is activated, the lights of the head and tail lights and turn on the engine.
The three most important of a car battery are / number of ampere hours, chemistry, and voltage. Car batteries have two terminals (+) positive and (-) negative. Battery acid is very corrosive and will eat through metal.
Batteries auto boot are usually lead-acid type providing a minimum of 12-volts. It works by connecting six galvanic cells, which are in series. Each cell has approximately 2.1 volts in a total of 12.6 volts. Lead-acid batteries, lead plates composed of separate plates and lead oxide. These plates Lead is immersed in an electrolyte solution of about 35% sulfuric acid and 65% water causes a chemical reaction that releases electrons as a result, As they flow through conductors to produce electricity. When the battery discharge starts, the acid reacts with the electrolyte material of the plates, changing the surface of lead sulfate.
Different types
Lead-acid batteries, different construction technique depends on the application of the battery. The flood cell stacks, which show liquid electrolyte are commonly used in today's time. AGM or absorbed mesh battery Glass is no liquid electrolyte is gradually gaining acceptance by users of SLI.
Specified batteries with SLI systems provides a strong current and has a low degree of discharge of each use. They are of many thin plates that are separated by thin dividers and have a higher electrolyte specific gravity, which reduces the internal resistance. Deep cycle batteries have fewer, thicker plates and have a greater depth of discharge in each cycle, but do not provide high current loads.
Use and Maintenance
Batteries with lead acid batteries require regular watering to keep the amount of water lost due to electrolysis in each load cycle. Recent designs have been reduced loss of water unless overloaded. Vehicle batteries modern do not need much maintenance, and often do not provide caps for adding water to the cells. These batteries have extra electrolyte above the plates, which allows the loss during the life of the battery.
The batteries must be charged on time if stored to retain their capacity. Stored batteries should be fully charged and clean of corrosion and deposits must be placed in a dry environment for its longevity. During the winter season, a shipper should be used to keep it covered. Cables should be fixed securely and shipped properly vent hose.
Cars Battery, the most essential of vehicle with two wheels or four wheels must be addressed properly. Without that your assets are incomplete.

Buy a used car can be risky because they do not know how the car was used by the previous owner. Furthermore, the price may be a primary consideration before we decide to buy used cars. Therefore, this article is to give some advice Important to get the best deal for the price of used cars.
The first thing you should do before buying a used car is to know the price in the market. You can obtain information on market prices by searching the Internet. From Internet, you will find many price guides, so you can make the comparison between prices and find the place to buy quickly.
In addition, the condition of used cars should also be carefully controlled. If you do not really know about the machine's car is fully suggested asking your friend who know more about the car engine. So do not come to the wrong decision in choosing a used car.
Also, another way to get the best deal for used car prices are about to determine the factors that affect May on car prices. For example, you must verify the age vehicles, general condition, market demand, mileage, and external defects or make sure that the car was good.
In addition, public auctions are also the confidence to get the best deal for used car prices. As usually held each year. So you can come to the auction of government and complete information on buying a used car there.
After obtained information from the previous review, can now start looking for a used car and find the price more affordable than you search. Good luck!

Well a 65 Watt portable charger works on a variable power of 75 watts?
Many answers here are confused about what the scores to meet supply charges. "75 watt" level of output of the inverter is a maximum * * Can supply, depending on load. This does not mean that investors will push 75 watts into the load, regardless of the load you want! Consider making a 120V in a typical home can provide about 1500 Watts … but you can connect to one watt "65" adapter, or "100" Watt bulb that question, no problem. It's the same thing. That is completely unnecessary to match the source and load power. You want the power supply providing at least * what should Loading … But if the source can provide more than the needs of the cargo, This is not a problem. If so, almost everything that plug into a wall outlet or cigarette lighter socket of your car for that matter, would immediately burn! The same applies to the current - Ampere - votes. Again, eg the cigarette lighter of your car is probably melted at 20 amps or less. The investor will have 75 amps watt perhaps 7 at full load, unless most of the time. Is this correct? Sure. As outlets in your home - the United States, which can provide 120V least 15 amps, some of them 20. The charger of your laptop needs less than one amplifier. This is not a problem. It will only take the current - and power - it needs. Now … align the requirements necessary tension. If you have a laptop that needs 15 volts and you have a feeder that feeds 18 years, probably a problem. (But perhaps not; power controllers in modern laptops are very flexible. I would not try, though.) Subject to the OP, the only question is, can suffice for Reverse-Power Adapter charger? (I say again: Be able to provide more than enough energy is not a problem.) Well .. . complication is that many small investors costs are not evaluated honestly, like many gears car stereo. But if the "75 watts" investor is an assessment honest, and "65 watts" is coming from the charger rather than production, then … almost certainly going to work. It will probably * * Work if the "65 watts is the output of the charger, too. Chargers are not 100% effective, so as to produce 65 watts per needs more like 75 Watts inches but your laptop is not necessary that 65 watts all the time. You can not even need 65 watts each, as many laptop manufacturers power options "balanced" or "The maximum life of the battery, turn the screen brightness down, not playing not the sound of loudspeakers at high volume - all remain energy consumption down. From a fully charged battery should help too. If the marginal source of energy is you probably will not be able to carry your laptop and recharge the battery at the same time, but should be able to do one or the other. I use a regular "90 watt" in the magazine "empower" Output flight which provides only 75 watts. It seems that it should work … but the "90 watts" on the charger, again, maximum grade, and the actual supplies - and needs - depends on the load, ie on what the laptop needs at this time. The laptop works While this manner, the information is "on the sector" but not "load".
