An Intro to Flashlight Batteries 🔋

In this video we go over common flashlight battery terminology, naming conventions, and features in order to become more familiar with cells used in torches. If you'd like to see a demonstration of the practical differences between various battery chemistries, check out this video: • How to Optimize Output... .

Now do follow up and expand on battery life vs chemistry. Etc Thanks for your insights.

[@PardonMyEnglish]

I did do this in the video linked in the description if you’d like to check it out.

Great video

[@PardonMyEnglish]

I appreciate that. Thanks for watching!

Thank you, sir!

[@brianaylsworth9159]

Great video I've learned a lot 🙏

[@PardonMyEnglish]

Fantastic! Then it was worth it 👍

Please test the batteries of the Xtra headlights. Diving related

yea built in and proprietary batteries are not my fav. I also don't like lights with charging ports. Awesome video!

[@PardonMyEnglish]

Thanks Dan!

Excellent video. Clear and well presented information. I'm afraid I break most of your rules 😀. I' do steer clear of integral batteries except for my keychain lights (Olight and Fenix) but I'm constantly getting more battery sizes and charging systems. I'm waiting on some 18340 batteries and tubes for 18650 lights and a longer tube to turn an 18340 light into an 18650. I had to try the 3.2V lifep04s in my I3Ts but again I complicated my life and picked up a lifep04 specific charger so I don't have to remember to set the battery type on my other 2 or 4 bay chargers. Now I need to find some lifep04 14500s. All I've seen is 14300 ones for solar lights.

[@PardonMyEnglish]

Thank you! For me I don’t think of them as rules, more like things I’d have done differently personally. The 14500 LiFePOs that I am using are from GTF and I’m pretty happy with them, in case that helps. And yes, the spare tubes are a great idea! I’ve been meaning to get a shorter one for my Sofirn IF22A.

Isn't there a much higher risk of fire and catastrophic battery failure if you attempt to recharge and use an over discharged unprotected battery ?

[@PardonMyEnglish]

Thank you for bringing this up and good point! Yes, charging and discharging unprotected cells does pose a higher fire risk than cells that have been properly cared for.

whats interesting is how 18650s were the og laptop battery of choice. almost all old laptops have 18650s in their bulky batteries. then tesla started using 18650s in their roadster and model s. i believe the early model 3's still used 18650s, but eventually tesla went to the 21700 in later model 3's and model y i think. the model 3's that are built in china continue to use lifepo4 cell chemistry (3.2v) and it is my understanding that with the switch to 21700's here in the US they will be switching to all Lifepo4's also in model 3's if they havent already. less range than lipol, less available max current but longer life. imo tesla and all the EV's being made now days are why batteries have gotten so insanely cheap.

[@PardonMyEnglish]

Wow, I didn’t know most old laptop batteries were using 18650s. I also didn’t know that about Tesla batteries either. I wonder if the switch to LiFePO4s was due to safety reasons (?). Thanks for sharing and I learned a lot from your comment 👍

[@grahamwinter5536]

👍👌😊

[@howyoudurrinhunneh]

I only have Olight so I don't mind proprietary batteries :)

[@PardonMyEnglish]

It’s good to have that consistency in my opinion 👍

[@deanparkes4644]

You didn't talk about amperage.

[@PardonMyEnglish]

I did at 6:55 but if you’d like to add more info, please do!

[@deanparkes4644]

Sorry I meant discharge rate.
