Batteries

NiMH batteries must be charged first. The charge won't last as long as an alkaline battery but they can be recharged 100's of times. They have a slightly lower voltage (1.2 instead of 1.5) and should work fine in many devices. For an electronic device, you may see a low battery indicator because of the lower voltage.

The GMT-12A is the GB Electrical GMT-12A 5-Function 16-Range Analog Multitester. Basically it allows you to test electrical current and flow in home applications, and some smaller electronics projects.

Extreme heat from direct sunlight can cause batteries to overheat, which can shorten their lifespan and reduce their efficiency. It is important to store and use batteries in a cool and dry place to maintain their performance. Additionally, prolonged exposure to sunlight can cause the battery casing to degrade over time.

No, biting a battery will not make it work better. In fact, biting a battery can be dangerous and may cause it to leak or rupture, leading to potential injury or harm. It is best to handle batteries properly according to the manufacturer's instructions.

If you could look at the system of a hurricane then you could notice two different things. the first main part of a hurricane is the eye. This is what you see in many pictures of hurricanes. The eye of a hurricane appears as a big hole in the middle of a big white circle. and the wind speed around it

You can make batteries create heat energy by increasing the current draw from the battery, which causes resistance in the circuit and generates heat as a byproduct. However, it is important to be cautious when doing this as excessive heat can damage the battery and pose a safety risk.

A wet-cell battery typically consists of lead plates submerged in an electrolyte solution of sulfuric acid and water. The electrolyte gives the battery its "wet" characteristic. The battery casing is usually transparent or translucent to allow for easy inspection of the liquid levels.

Power output / Power input * 100 = %Efficiency For instance, 746 watts is equivalent to one horsepower. If an electric motor were 100% efficient, a 1HP motor would only draw 746 watts of electricity. Look in any motor catalog, and you will see that typical 1HP motors draw around 1100 watts. So: (746 / 1100) * 100 = 67.8% The example motor has a 68% electrical efficiency. You can apply the same formula to any electrical device - heaters, amplifiers, transformers, etc.

amps*volts=watts

40 amps *12 volts= 480watts

watts/volts=amps

480watts/110volts=4.36363636amps

So you need a 110 volt generator that can produce about 5 amps as a bare minimum.

To take into account system heat loses that occur when converting power consider doubling it to be safe. (this is over kill but the advantage is that your generator is not working at full capacity at all times)

In a sine wave inverter, during inverter operation the four switches of the H bridge are switched using sine wave PWM signals normally generated using a µ-controller or an analog circuit. One upper and the opposite lower switch is switched in sequence with necessary delay between the two. This will continue for one half cycle and the other two switch pairs are switched during the next half cycle to make a full sine wave output. During Mains mode, the same transformer used to inverter and boost voltage to line voltage in inverter mode is connected to the mains power using a relay. A bridge less rectification principle is used to charge the battery by boosting the voltage produced in the transformer primary using the inductance of the winding,by switching the lower MOSFET banks.. The lower MOSFET switches are switched and upper switches kept turned OFF, The body diodes of the upper MOSFETS will act as rectifiers . The pulse width of the switching pulses of the lower bank is proportional to the output current , voltage. By varying the pulse width variable currents can be obtained. The current is sampled and fed back to the control circuit to limit and obtain variable power levels. PF correction can also be obtained during charging using PF correction control circuit in the charging mode.

No, LR6 and AM3 batteries are different label codes used for the same type of battery, which is commonly known as AA batteries. They both refer to the same size and type of battery with a standard voltage of 1.5 volts.

Duty cycle is the percentage of time a system is active or in the "on" state compared to the total time of operation. It is commonly used in electronics to describe the ratio of the time a signal is high (on) to the total period of the signal. A 50% duty cycle means the signal is on half the time and off half the time.

I purchased 4 rechargeable batteries plus battery charger July 2006. I take many photos for my eBay business and have found that in the last few weeks when I recharge the batteries, they only last for a few photos. I thought rechargeable batteries lastest more than 2 years. Can someone let me know the life of rechargeable batteries. Thank you.

Batteries use acid to derive electricity, and this acid is known as battery fluid or 'juice'. Which acid any certain battery contains depends on who made it, why, and what technology was available. The related Wikipedia link offers an extensive list of battery types.

Before using a rechargeable battery for the first time, it's recommended to fully charge it to establish a full cycle and optimize its performance. Make sure to follow the manufacturer's instructions for charging times and methods to ensure the battery's longevity and efficiency.

Aluminum foil does not give power to batteries to light a light bulb. The common batteries that we use in flashlights and portable electrical/electronic devices, like the "D" cells, "C" cells, "AA" and "AAA" cells, are made with a zinc can. This zinc outer container for the battery has two jobs. It acts as a housing to contain the electrolyte, and reacts with the electrolyte to create voltage. There isn't any aluminum involved. The actual chemical reactions involved in the generation of voltage in the zinc-carbon or zinc-manganese (the "alkaline") cell can by found by surfing the link to our friends at Wikipedia. They're down with all this. And you can be to.

They usually contain lead, lead sulfate, and sulfuric acid.

Yes, it is possible to charge someone with aggravated battery without committing simple battery. Aggravated battery involves causing serious bodily harm or using a deadly weapon, while simple battery usually refers to intentionally causing physical harm or unwanted physical contact. Aggravated battery typically involves more severe circumstances that elevate the charge from simple battery.

No, alternating current (AC) can also be used to charge batteries using a charger that converts AC to DC. The charger will convert the AC power from the outlet to DC power that is suitable for charging the battery.

Some people believe in the concept of "electromagnetic hypersensitivity" where individuals experience symptoms around electromagnetic fields. However, scientific studies have not definitively proven its existence. To help mitigate the situation, you can try grounding techniques or seeking guidance from a healthcare professional for potential solutions.

Using an 18 volt charger for a 14 volt battery can potentially overcharge the battery, causing damage and reducing its lifespan. It is best to use a charger that matches the voltage requirements of the battery to ensure safe and efficient charging.

A Solar Battery is basically a tank to catch the power from a solar installation. The power is caught by the battery, and stored until it is needed. There is not really a "SOLAR BATTERY" per se, many are great at the application.

The main thing to consider is the fact that the battery has to catch power and give it back over hours or days, not seconds or minutes. Car batteries are designed to give all their power in 20 seconds and are therefore not an acceptable item for the application.

Deep cycle batteries are used in solar applications because of their ability to hold a charge and discharge it over time to an appliance like an inverter.

Premium Deep cycle batteries are a bit more expensive than normal ones, but you get cycle life (number of times you can charge and discharge the battery) and density (amount of power in a small box) that the cheaper batteries can not match. In addition the premium solar batteries are UL listed, providing an ability to insure the installation in a building or home.
