What are the Signs of a Bad Car Battery?

A car's battery is one of its most essential components. It is responsible for starting the engine, and minus it, the car can never start. But car owners hardly take care of it. Throughout their lifecycle batteries are subjected to continuous phases of charging and discharging and also high heat environments. As they aid the vital purpose of getting the engine started, when they actually fail, they can leave the car stranded and cause an immense problem for the driver, as well as, the car owner. So, it should be serviced or replaced whenever necessary.

According to experts, the average lifespan of a car battery is around five years but improper maintenance can cut the lifespan considerably. Therefore, it is certainly a good idea to know the signs of a bad car battery. The typical symptoms of a failing car battery are as follows-

Engine starts cranking and refuses to start

While starting your vehicle, if your car engine refuses to start then the real perpetrator is the battery. Owners often have this misconception that this is owing to a bad starter and at times thinks it to be an alternator issue.But most of the time, the problem is due to a dead car battery.

The car batteries might recharge if an alternator is used. But this will support the battery for few days only. It is better to look for a new battery.
Starts fine but stops the very next instant

This is a persistent issue in a dead car battery. Such signs demonstrate that either the battery has loose or broken terminals or any sort of parasitic pull. In such cases, first, you require checking the cables of the battery. Ensure that the firm fitting of the cables to the exact points. If you find that there are no problems with the cables and terminals, then perhaps it is the time for replacement of the battery with a new one.

Car accessories just refuses to work

This is one of the best methods to know that the actual problem lies with the battery. The battery is the lone part that backs all other parts and accessories to work smoothly, particularly when your alternator has stopped working. So, whenever you notice that your car does not display any signs of life, then surely the car battery needs to be checked.

Car makes a clicking sound when the key is turned

We have all faced this moment many times. When you turn your key in the ignition, your car only makes a ticking noise. It's a definite indication that you've lost your car's battery. The battery is either dying or absolutely dead

The car just won't start unless you give it gas

If you need to give the car some gas in order to propel it to start, your battery is possibly going to die soon.

It is essential for the car owners to understand these symptoms of a bad car battery so that they can deal with the approaching problem.

How to Determine Battery Sizes when using Pure Sine Wave Inverters - Garg Electrical

How do you power all of your electronics with no outlets available? Batteries are the answer! They can store plenty of energy depending on their capacity, and by utilizing pure sine wave inverters, you can take DC energy a battery puts out, and transform it to AC energy to simulate a wall plug. Pure sine inverters, sometimes referred to as a true sine wave inverter, create an energy that is friendly to most modern-day devices, such as electronics with microprocessors.

We often get calls asking, “What size battery do I need to power my Pure Sine Wave Inverter?” And, I admit that is a fair question to the beginner, so we’re here to educate our customers so they know exactly what size battery to buy.

When using true sine wave inverters, you’re powering the sine wave inverter by connecting it to a battery or battery pack. Once the pure sine inverter is turned on, it starts to invert the DC energy to AC regardless if a load is applied or not (I’ll talk about this parasitic draw later). When a load is applied, electricity is pulled out of the battery, energy is inverted, and you can now run your device. So while the beginner’s question seems right, what you really need to ask is, “What size battery do I need to power my 120 VAC device run through a battery inverter?”

Now, I know that seems like a mouthful, but that is really what we need to know in order to size your battery correctly. It isn’t so much about powering the inverter, as it is more about what your device is actually pulling out of a battery through an inverter. This may be a great place to mention that changing electrical form from DC to AC is called “inverting,” while changing from AC to DC is “converting.”

Sine Power Wave Inverter Sizing

Sine wave inverters come in all sizes, from a small micro sine wave inverter, to larger kilowatt pure sine wave power inverters. When choosing your sine waveform inverters, you need to make sure you are selecting an inverter that covers your total watt draw. Also be sure to account for a possible surge draw. Most devices such as laser printers, pumps and compressors take a lot more energy to get started, and it isn’t always listed on the device. It’s a good idea to ask the manufacturer to verify if there is a surge amp rating for the item you are trying to run. As a general rule you will need to oversize your inverter to load by as much as 75%. Meaning, if you have a 200 watt load, you should start looking at a 300 watt-sized inverter.

Now let’s talk about inefficiencies and that parasite draw. By just simply powering up the inverter, there is a no-load-draw, or what’s commonly referred to as a parasitic draw coming off the battery pack. It is a good idea to power down the pure sine wave power inverter if you are not going to be using it. Depending on the inverter, you could be losing around ½ an amp an hour if it comes with a power save mode; up to 3 amps or more if it does not. You can get an idea of how much parasitic load your inverter has by looking at the efficiency rating in the specifications.

Determining Load and Battery Pack Size

So can your inverter run your appliances, a small cabin or an entire household? Yes, they can, if the inverter rating matches your total load, but often times you want to weigh the cost. Pure sine power inverters can really run anything as long as the device falls within its specification. However, what you need to remember is the battery pack needs to be suited for the device you plan to run. This means you’re going to have to gather some specifications before you even try to size the battery pack. Start with our calculator for sizing a load.

Now that we’ve covered some of the basic information, you can start to size your inverter. First, you need to know what wattage inverter to select. Some devices are labeled with a wattage, but many are just listed with their voltage and amperage rating. Remember, all inverters are simply pass-thru devices, meaning your inverter rating is simply the MAX power (in watts) that it can invert at any one time. Stated again, you cannot use a 100 watt inverter to power a 200 watt load because the inverter is not capable of inverting that much energy without causing harm! Use the following formula to calculate the wattage:

Volts x Amps = Watts

Once you have the wattage figured out, it’s a good idea to figure out what size battery pack you will need. In general, higher voltage inverters are more efficient and consume less energy during the inverting process. In the end you need to determine a battery or battery pack that is capable of running your load for as long as you anticipate.

Our DC to AC Amperage Conversion Calculator takes into account the inefficiencies of inverters, and the amperage they consume just by inverting DC energy to AC. It will tell you the hourly DC Amp draw your devices will consume.

We hope this information will help you in selecting the proper inverter and battery pack for your next project.

How to choose the right inverter and battery for your home?

Planning to buy a new inverter or upgrade the old one? Whatever the reason, it is very important to understand the right inverter and battery for your home.  Want to choose the best configuration? You would need answers to the following questions:-

• What is your Power requirement?
• What VA rating will you need basis your requirement?
• What will be the right battery for your inverter?

Let us first understand your Power Requirement

One of the most important thing that you must know before buying an inverter is your “power requirement”. In simple words- what all electrical appliances (like CFL, tube lights, fan, television, computer, refrigerator etc.) you will run at the time of power cut. Power requirement is addition of the power consumed by various electrical appliances.

Suppose you want 3 Fans, 3 Tube lights, 8 LED lights, 1 television & 1 refrigerator to operate at the time of power failure. The power consumed by these items will be total of the power consumed by these individually:

1 Fan – 70 Watts

1 tube light – 40 watts

1 led light – 7 watts

1 led television – 70 watts

1 Refrigerator - 140 Watt

Therefore your total power requirement is (3*70 +3*40 +8* 7 + 1*70+ 1*140) = 596 watts

Find the VA rating of the inverter you need

VA stands for Volt ampere rating. It is the voltage and current supplied by the inverter to the equipment. Your appliances need more VA than the power requirement in Watts due to the nature of the devices. The ratio is called Power factor.

Hence Power supplied (or VA rating of inverter) = Power requirement (power consumed by equipment in watts) / Power factor.

Usually at homes, power factor ranges from 0.65 - 0.8, taking 0.7 for the calculations,

Power of inverter (VA) = 596/0.7 = 851 VA

So an inverter with 900 VA will be the right choice for your home

Know the battery your inverter needs

The performance of an inverter largely depends on the battery. Battery stores the energy needed to run your appliances during power cut. The next big question is “how much back up will an inverter provide?” or for “how many hours it can run all of your appliances?”. This is determined by battery capacity. It is expressed in Ah (Ampere Hours).

Luminous batteries are available from 60 Ah - 220 Ah, so how will you finalize which one do you need? To find this out let’s do a reverse calculation. Consider that you need a battery that provides back up for 2 hours for running appliances of load 851 VA (596 W).

Battery capacity = Power requirement (in VA) * Back up hours (in hrs) / Battery Voltage (in volts)

For lead acid battery, battery voltage = 12 V.

Battery Capacity = (851 * 2) / 12 = 142 Ah

In reality battery performance degrades with usage, so you are recommended to buy 5-10% higher capacity battery.

Therefore a battery with a capacity of 150 Ah will work for you.

So if you want to run 3 Fans, 3 Tube lights, 8 LED lights 1 television & 1 refrigerator for 2 hours during power failure you would need 900 VA inverter and 150 Ah battery.

Single Battery or Double Battery

Now suppose your power back up requirement is 4 hrs for the same power load.

Battery Capacity required = (851*4) / 12 = 284 Ah ~ 300Ah

Since batteries are available between 60-200Ah, you will need 2 battery of 150Ah (in series) to provide 300 Ah. Two batteries together create 24 V output, hence you need to choose inverter which supports 24V input.

Battery plate type

Lead acid batteries come in flat plates or tubular (rod shaped) plates.

Flat plate batteries come in small height containers, and are suitable for low power cut areas as their designed cycle life is low.

Tubular batteries come in small as well as tall containers, they typically have longer design life, suitable for all areas. Due to the longer life, they are replacing flat plate batteries in inverter battery applications.

Plates should be constructed from highly pure lead alloy with high pressure casting machines to ensure low maintenance and long life.

Other Features

When buying you may consider other features such as

• Warranty: Higher warranty indicates longer life and superior quality. Typically, warranty on batteries range from 12 months to 48 months.
• Float indicators & vent plugs: Batteries have conveniently placed visible float indicators, so that you don’t miss topping up water when needed. Vent plugs should be designed to ensure that the gas pressure inside the battery is regulated.
• Terminal Protectors: Batteries should come with terminal protectors to ensure utmost safety to the consumers. These protectors prevent chances of accidental electrical shock.
