Maintenance and Use Tips

Be sure to follow manufacturer guidelines for care of your rechargeable flashlight, as they function differently from other electronic products. Rechargeable flashlights may work best if you allow the built-in battery to fully drain before charging it back to full capacity.

Chances are that you bought (or will buy) your light for a specific use. If this is the case, there will be natural wear and tear. Whether you use it at a construction site out on your camping and hunting trips, it will be a critical tool that you want to function at its best every time you grab for it. Like anything, in order to make sure that this happens, it is critical that you take care of it.

Cleaning your flashlight

However, cleaning and maintaining your flashlight may seem minimal, but it is an important task. Hopefully, your flashlight is not corroded. In a few simple steps, you can prevent corrosion and ultimate destruction to your flashlight. Your flashlight will last as long as the LED does, so while you keep it in great shape, you will get the longest use out of it. Maintaining and cleaning your flashlight with the following steps 1-2 times per year will have it looking and performing like new anytime you need it.

Clean the outside

It is important to get rid of any dirt or grime from the outside of your flashlight. You can do this by using alcohol pads or other grease removal cleaner. Another great tool to utilize is a bristle brush to get into all of the grooves, too. A bristle brush can be anything from a standard brush to a toothbrush, depending on how large or small of a space you are trying to get into. The last piece to cleaning the outside of your light is wiping down the lens. The best thing to invest in is a scratch-resistant lens, which will clean easiest with a quick wipe to make it look like new.

Cleaning the Inside & Battery Contacts

Other than cleaning the outside, making sure the inside of your flashlight is clean is another crucial area. First, you will have to remove any of the batteries in your flashlight if you have them. Use the same tools as with the outside cleaning for internal cleaning. You will also want to check that the springs are working correctly as part of maintenance. As for outside cleaning where a toothbrush is handy, another household item to use especially for internal cleaning, is Q-tips. They are gentle and can get into tough to reach spaces.

Another cleaner tool that you can use is something like DeoxIT, which is a cleaner that is specifically designed to clean and enhance electrical contacts.

Lubricate

This might not seem like an intuitive part to maintaining the life of your flashlight, but lubricating the flashlight makes sure that it unscrews smoothly and that the O-rings do not dry out. One tube of lubricant will last you a long time, so this is not something that should be an expensive investment, making it even more worth the buck.

All you have to do for lubrication is simply cover the surfaces that need it. Do not cake it on. To lubricate the O-rings, make sure you cover the entire surface. If you can, fully remove the ring to do this. If you are unable to remove it, you can also just apply the lubricant over the surface while it is still attached to the flashlight. Again, you do not need to use a ton of product, only what is needed.

5 Tips for Maintenance

  1. Avoid damaging your eyes or other’s eyes when checking simple maintenance. Do not shine the light towards your eyes when checking to see if it works.
  2. Do not exceed 6V with your rechargeable flashlight (unless instructed to by manufacturer, though it is safest to follow this tip). Make sure that the positive electrode of the battery faces the front end of the flashlight and the negative faces towards the tail. Not paying attention to this can result in burning out the circuit board. Avoid opening the circuit board if you are not trained in it.
  3. Pay attention to your flashlight’s temperature. Do not leave it out in high-temperature environments.
  4. When you are not using your flashlight, remove the battery and store it in a cool and dry place. This will help preserve the life of both the body of your light and the battery. Also, do not overcharge the battery.
  5. Clean your flashlight! Simply taking a cloth to the body and parts every 6 months or so will keep it performing at its peak. Adding some lubricant as suggested above in the cleaning and maintaining tips also helps. However, if the O-ring is waterproof, skip putting any oil rub onto it as this could erode the O-ring.

Criteria For Evaluation

We used the following criteria to evaluate a number of rechargeable flashlights on the market and narrowed down to the top 15 choices.

Ease of Use

The first criteria that we looked at was how easy it was to use the flashlight. This covers cycling through the various modes, changing and charging the built-in batteries and any additional settings. Flashlights with minimal buttons on the surface are preferable so that they can be easily used in the dark. We excluded products that require more than one hand to turn on the flashlight.

Brightness

flashlight brightness

Brightness was the next criteria we evaluated. We went through all available brightness settings, matching each product’s lowest, mid (if applicable) and highest settings. We rated brightness and power settings independent of its size, however we did consider product weight in relation to brightness.

Size

We evaluated product size (length only) in relation to weight. . This ensured that most of the products could comfortable fit into pockets, small bags and other carrying items commonly used during camping, hunting, or other common outdoor activities.

Durability

We evaluated product durability against factors such as scratch resistance, strength of the casing and water resistance. but didn’t put all of the focus on resistance to elements like water. So being waterproof didn’t guarantee a high ranking, even if it is a desirable quality. Durability was all about how much of a beating the housing of the flashlight could take. Scratch resistance ranked high, and little things like buttons worked their way into our final decision in the durability criteria. The tougher the flashlight, the higher it is ranked. Some of these flashlights gained great favor for being usable in hunting sessions, proving that you didn’t need a specialized model for the activity.

Battery Effectiveness

Battery effectiveness was based on how quickly the batteries charged, their ease of removal, cost of batteries and of course whether they dulled the brightness when they were running low. Automatic dimming of a flashlight when the batter is low is both unnecessary and annoying. Not every product does this, but we adjusted the list in favor of the products that don’t. We were able to balance the list, putting the flashlights with the best performing batteries in their proper place.

Features and Modes

Battery effectiveness was based on how quickly the built-in batteries charged, their ease of removal, cost of battery replacement and the level of brightness when the batteries were run low. Some rechargeable flashlights automatically dim brightness to conserve battery life, however we prioritized flashlights that do not have this feature.

Design

We evaluated design elements based on how well they worked in everyday settings. Small things like clips, lanyards, and rubberized material can be particularly helpful for tactical or high-intensity activities. . We selected the designs that have the most impact on ease of use.. While aesthetics weren’t considered high priority, it still shouldn’t be ignored as a primary consideration.

Accessories

rechargeable flashlights accessories

Finally, we assed any included accessories. Products that included add-ons like a charger, extra built-in batteries, attachments and a case were prioritized. The less a customer has to purchase separately to enjoy their new flashlight, then the higher the rating.

FAQs

Frequently Asked Questions

Q: Do you have to fully charge rechargeable batteries before using them?

A: You will likely need to charge the batteries before your first use. Charging batteries to their full capacity (or discharging them then charging) before use is done to keep the battery fresh. Like all batteries, misuse over the years will slowly degrade their optimal performance.

Q: How long do rechargeable batteries last?

How Long Do Rechargeable Batteries Last? Rechargeable batteries lose their top capacity over time the more they are used, and this is unavoidable. The loss of top power isn’t really that bad since it takes thousands of recharges to even get to that point. And even when it loses the ability to be topped off, the batteries still maximize at a good portion of their power, around 80%. The drop off isn’t really that noticeable unless you are using them for hours at a time per day. But the bottom line is that it doesn’t bother the brightness of the light or its normal functions other than total runtime.

A: Rechargeable batteries lose their top capacity over time the more they are used, and this is unavoidable. The loss of top power isn’t extreme since it takes thousands of recharges to degrade. When a battery loses the ability to charge to full capacity, it still utilizes a good portion of their capacity, typically around 80%. The bottom line is that it doesn’t bother the brightness of the light or its normal functions other than total runtime.

Q: What features are most important in a flashlight?

A: Lumens, runtime, and bulb life are important features to consider.

Q: Why are LED’s preferred?

A: LED’s have long since been the preferred light bulbs for portable flashlights due to their long lasting life and energy efficiency. They are found in more than just flashlights and have become the default bulb type for a variety of home and office products. The smaller housing of the LED flashlight allows for increased efficiency, and often lasts for the lifetime of the device.

Q: Do you need an extra product to recharge?

A: This will vary since not all rechargeable flashlights come with removable batteries. If the product allows it, you can charge their batteries by plugging in the flashlight, just like you would with other electronic devices. It’s an ideal solution for consumers that don’t want to take the batteries out to charge them. When dealing with removable batteries that can be recharged, you have the option of putting them in a supplied charger. Not all products come with a charger, and it may be necessary to purchase one separately.

Q: What are some of the most favorable modes?

A: Moonlight, strobe, and SOS are the commonly available modes in a rechargeable flashlight.

Q: Will a crack in the glass make the flashlight useless?

A: A crack won’t make the product completely useless, however it may cause the lens to occasionally fog up. They don’t have to be deep cracks for this to happen, so even a small break could spell trouble. When the lens fogs up, brightness may dull. Is is also possible that water can be introduced into the flashlight through a crack. It is recommended to repair a crack in a flashlight as soon as possible to minimize damage.

Q: Is there a way to prevent shortened battery life?

A: There is no foolproof way to guarantee that a rechargeable battery will keep 100% of its charge for a lifetime. But you can maximize the use of your flashlight by following all manufacturers guidelines for care, use, storage, and charging. If you’re not going to use a flashlight for weeks at a time, it is best to remove the batteries (if they’re removable) and put them in a safe place to avoid corrosion.

Q: How do you clean a rechargeable flashlight?

A: As always, follow the specific product guidelines for cleaning instructions. Typical cleaning may include wiping the lens with a microfiber cloth and light cleaning of the battery contacts.

Q: Are the flashlights waterproof?

A: Only some flashlights are waterproof, and some have such low resistance to water that they may be damaged by condensation. Consider the level of water resistance you’ll need for your preferred activity when selecting a flashlight.

Q: Is it important to have a carrying case or pouch?

A: A carrying case is a personal preference and likely depends on your intended use. Some rechargeable flashlights are small enough to fit in your pockets. Other accessories such as lanyards and clips may also be available.
