These protections also assist in prolonging the life of the lithium battery.īattery protection circuits will prevent over-discharging, over-heating, and discharging too quickly. Some manufacturers supply lithium battery protection like overload, overheat, and over-discharge safety guards for their flashlight (among other) devices. Here’s a list of lithium battery sizes by number and a short description:ġ4500 – Similar in size to a regular AA batteryġ6340 – Close to the size of a CR123A batteryġ8650 – Also similar to a AA battery size but with a larger girth and length, the 18650 is most popular for flashlight useĢ6650 – Much larger high-power battery, devices are made specifically for these batteries Lithium batteries aren’t typically advertised in sizes like AA, AAA, C, D, etc. Depending on the type of flashlight you have will depend on which size battery you require. Shapes and sizesĪnother huge advantage of lithium batteries is that they come in numerous shapes and sizes for convenience. You might end up saving yourself money on having to purchase new batteries every time their charge runs out by getting up to 1000 or more charge cycles per battery. The number of times you can recharge your lithium batteries will depend on how you keep them stored, how you use them in the device, and if you charge them correctly. Lithium batteries are more expensive than other types of batteries. Once the voltage sags and reaches the required voltage point of the flashlight, the light emitted will be the same as any other battery used. Although they have an average advertised voltage of 3.6V or 3.7V, when fully charged, they can supply up to 4.2V.īecause of the slightly higher voltage supplied in lithium batteries and the lower internal resistance, lithium batteries allow more voltage to reach the bulb in a flashlight which produces a brighter light. Lithium batteries hold more energy and can discharge their energy faster than other types of batteries. Lithium batteries, if stored and maintained correctly, have a longer shelf-life expectancy because they are a low self-discharging battery. The self-discharge of a battery is a chemical reaction that will be affected differently depending on how your battery is stored as well as the state of charge when stored.
Higher self-discharging batteries have a lower shelf-life expectancy. If manufacturers give a warranty date, 2-3 years, for example, you should expect that your lithium batteries will last around that or beyond that timeframe as long as they are used, charged and discharged properly.
Lithium batteries are designed to last longer than other standard batteries (alkaline) and that’s exactly what they do if cared for appropriately. Here is a list of the advantages of using lithium batteries in flashlights: Longer run time Not only is their ability to last longer in flashlights a great advantage for those of you who need longer run time at night, but there are multiple other benefits to using lithium batteries in a flashlight. They have the advantage of high-energy-density which gives them benefits over other standard batteries. Lithium batteries, if used correctly, are good for flashlights. Are Lithium Batteries Good for Flashlights? Read on to power up your knowledge of the best batteries to use in a flashlight. It’s confusing and the research is time-consuming, so we’ve done it for you. When it comes to using batteries, there are certain types that will be better used for different objects.
With so many different types of batteries available it’s hard to choose the right ones for your flashlight. Not only is their shelf-life and run time longer, but they also produce more energy for brighter lights. Lithium-Ion or Lithium batteries last considerably longer than other batteries. Lithium batteries can be used in some quality flashlight as an alternative to standard batteries. In the meantime, did you know that the batteries you use in a flashlight can modify how long the flashlight lasts and how bright they can shine?
