How to Extend the Battery of a Projector?

How to Extend the Battery Life of Your Projector?

June 16, 2020

Imagine planning a perfect movie night with your friends with popcorn and drinks in the cooler. Having decided to spend the summer night watching a recently released movie and 20 minutes into the movie, the projector goes off! What about you getting to the middle of your presentation with a new client and then your projector goes off on you. Those are very disappointing scenes that no one will want to go through. And with the increasing popularity of mini projectors, they happen more frequently than you think.

Now before you go canceling out a mini projector from your to-buy list, you should know that there is a lot we can do to improve the projector's battery lifespan.

In this post, we will be answering a frequently asked question "how can I extend my projector's battery life?" In addition, we will show you a number of commonly made mistakes which may shorten the battery life and share important tips with which you can maximize your projector's battery.

Ways of Maximizing Your Projector's Battery

1. Taking Care of the Projector

While this might be the simplest rule in ensuring long battery life, it is also the most ignored. Like every other electronic device, the key to enjoying the natural life span is to take proper care of the projector.

Especially if you are someone who makes use of your projector every now and then, it is important for you to take the needful measures in order to make sure it works in optimal condition. If a projector is working in a condition other than it is supposed to be, it has adverse effects on it.

You have to ensure that the other parts are working as they should be. And these include the lamp and the projector fan as they are the major parts that consume the power. If they are not at top conditions, the projector consumes more power than it should be and in turn, it weakens the battery as time goes by.

2. Having a Backup Battery

Although you are using your projector just for entertainment, it wouldn't hurt to get another one as you might be annoyed if it breaks down in the middle of an interesting movie. Average batteries of the projectors in the market last between 90 minutes and 2½ hours. Thus, it is much better for you and for the sake of the battery to use a backup instead of using it up eventually.

Since the batteries are fairly cheap enough and portable, an extra should be carried if you are not sure that the current charge would be enough for you to play throughout a journey.

3. Keeping the Projector in Appropriate Weather Conditions

The projector should always be kept in a cool, dry place. It should be kept away from high temperatures or direct heat sources (such as radiators, campfire or electric heater), damp areas, and direct sunlight.

It is more often than not to see people leave their projectors in the car, which may affect the battery as the projector is exposed to either very hot temperature (in the summer) or very cold temperature (in the winter).

4. Use the Correct Charger and Power Adapter

One of the commonly made mistakes that can spoil your battery is using incorrect chargers and adapters. Batteries have their recommended current and voltage requirements, which can only be supplied by the chargers and adapters provided by the manufacturers. This is why it is important to ensure that you use the recommended charger to charge your projector.
If by any means the charger or adapter gets spoilt, then the replacement should be requested from the manufacturer or their retail agents. As it is much cheaper to buy a new charger or adapter than to get a new battery.

5. Setting brightness at Minimum Level When Possible

One of the major consumers of power in a projector is the brightness. The higher the brightness at which the projector is used, the faster the battery drains. The projector can be used at minimum brightness to conserve battery life. However, it should allow the images or videos to be viewed clearly on the other hand. In this way, the projector uses less battery power.

6. Proper Charging Etiquette

Since the lifespan of the battery depends on how it's been used and charged, we should also emphasize the way the battery is charged.

  • All new projectors should be charged for 3-5 hours before the first use.
  • The projector should always be charged before it shuts off automatically. Note that the projector will automatically shut off when it reaches a 15% battery level.
  • Always power off before charging. Powering the projector off before charging reduces the charging time because the battery charges faster when it is switched off.
  • Keep it in mind that the battery charge capacity begins to weaken when it is charged and discharged. It means that the battery doesn't last as much as it used to after a particular period of time.

Battery Maintenance Tips

Apart from the important steps that being analyzed above to show you how to elongate your battery life span, there are some other tips that may help increase the lifespan even further.

#1 Remove the battery whenever it is not going to be used for a long time.

It is important to always remove the battery when the projector is not going to be used for at least a week or more. This prevents the battery from leaking and corroding the slot assigned to it.

#2 Charge and discharge the projector by turning it on at least once a month.

For those who do not use the projector frequently, it is possible that the projector may go months without in use. In order to prevent the battery from going completely useless, it is important to charge and use up the battery at least once a month.

#3 Understand how you should store a battery properly.

Batteries can be very tricky to store or keep for a very long time. It is necessary to know the proper way to charge a battery before keeping to prevent it from getting spoilt.

Do not store a fully charged battery before storing it, this is because the battery might lose the ability to be fully charged again. Even worse, it may affect the battery and cause it to lose the ability to be recharged.
If you realize that you will not use your projector for at least one month or more, you need to charge it into 50% before you store it.

#4 Use an appropriate lamp.

The output of the projector comes from the lamps, which is also one of the most power-consuming parts of the projector and that is why you need to make sure that you are using the correct one.

One of the best ways to ensure that your lamp is still usable. You may have to know why it is not usable when using a lamp, you might wonder how an unusable lamp can still show pictures. This is because you are using a lamp that has passed its lifespan. The lifespan of a standard lamp is about 2,000-3,000 hours, and using a lamp beyond its lifespan has many disadvantages. One of those is that it drains the battery faster.

Also, using an incorrect lamp might also cause the battery to drain. This includes fixing a 300-watt lamp bulb into a projector which allows a maximum power of 200 watts. The picture brightness will still remain the same, however, it may cause the projector to heat up, and the battery is drained faster and spoiled as time passes by.

Thus, it is important to check requirements for replacements before taking any measures.

#5 Avoid a fast charge.

Except when you are in a hurry to get a full charge on your projector, it is better to avoid fast charging. Fast charging involves loading the battery with more current and voltage than usual.

If possible, it is better to charge the projector with a USB cable connected to your computer. Although this may take longer to get charged, it ensures the battery gets steady current and voltage. And it is useful to preserve the life of the battery.

Conclusion

By now we believe that you have realized how proper maintenance of the projector's battery can help to save money in the long run.

In addition, we hope you have learned some valuable tips that can be used in maintenance. Although these maintenance tips may seem unnecessary and strenuous, religiously following the above guide will help maximize your projector experience.

Instead of stretching your budget on replacement batteries, going through these can help you use the battery till its natural lifespan.
