In other words, the luminance with the greatest lumens may not be the brightest. However, elements like reflector design and lens dictate how far and wide the light is cast. Theoretically, the higher the lumen count, the brighter the light. Lumens are how a bulb's brightness is measured. So you need to consider certain factors to help you choose the best rechargeable flashlight you’ll use. The market is filled with different types of flashlights, and this can make it difficult to choose the best one for your needs. If you are a person who is in need of a reliable light source for any occasion, you should not overlook the benefits of investing in a rechargeable flashlight. Flashlights that run on rechargeable batteries typically run on lithium-ion or li-polymer batteries, though there are other types of rechargeable batteries. For those who may not know, a rechargeable flashlight refers to a flashlight you can charge directly usually with a micro-USB or USB-C cable, but some do come with proprietary charging cables. There are many factors that you should consider when deciding to buy a rechargeable flashlight or a flashlight that runs on rechargeable batteries. Factors to Consider In Choosing A Rechargeable Flashlight However, this is easily offset since single-use batteries will be incrementally more costly in the long run. Rechargeable batteries can be a bit more expensive than their AA battery counterparts. If you have a USB rechargeable flashlight or a battery charger, an external power bank might help you out. Once your rechargeable flashlight runs out of juice in a power outage, you'd be in trouble. With this reason in mind, you can use your flashlight to illuminate pathways or items in case of power outages. This reason can be a deal breaker, especially for people who use flashlights for work purposes or store them in small drawers for home use.Ī rechargeable flashlight and rechargeable battery need to be charged for them to be used. While it's true that some rechargeable flashlights are small, most are still bulky to facilitate the bigger batteries. The Downsides of Rechargeable Batteries Bulkier Batteries Thus, rechargeable batteries are a more eco-friendly choice between the two. Rechargeable batteries have longer lifespans than non-rechargeable ones, which are single-use batteries. While it's true that all kinds of batteries will harm the environment, this can only happen once it's discarded. For a whole year, your battery purchases will be upwards of $100.Įven if you don't use it that much, AA batteries have been known to drain and leak when not in use which can damage the flashlight or leave you without power during a storm Environmentally- Friendly If you use your flashlight constantly, you'll probably have to change batteries once a week. Let's say it costs you $2 to change a battery of a flashlight that needs three pieces of AAA batteries, which gives you about 2.5 hours of light. While it's true that a USB rechargeable flashlight can be more expensive than the battery-operated ones, it can become the cheaper of the two if you consider the long-term costs. When you drain an alkaline battery quickly, like a flashlight, it will heat itself and the device, which can be a major hazard. On the other hand, alkaline batteries have higher internal resistance, perfect for low-power devices like remotes. Rechargeable batteries have low inner resistance, making them ideal for a high and constant power flow. This process makes them more capable of delivering the required output for high-drain devices like flashlights like rechargeable LED flashlights. Rechargeable lithium batteries have a higher power capacity compared to AA batteries. In this article, we'll take a look at the pros, cons, and factors to consider when considering purchasing a flashlight with rechargeable batteries. But what about on the other side of the spectrum? Are flashlights with rechargeable batteries any better? However, many flashlights are powered by AA batteries, which can be expensive to replace over time. People can use them to navigate dark places in case of power outages or shine a light on whatever we're working on. Flashlights are an essential part of home emergency kits or toolboxes, whether they use rechargeable batteries or non-rechargeable batteries.
