I Tested Rechargeable Batteries From Amazon! Which one is the best?

Draining and recharging the batteries once a day is a hell of a commitment to make! Glad to see you're so dedicated to this!

Finally! Tyler starts an episode by ACTUALLY CHARGING THE BATTERIES FIRST!

[mariestarlight]

Holy shit, that's quite a commitment. I'll be looking forward to the future test in a year. Keep in mind if you want to get through 1000 cycles in a year, you'd have to charge and discharge them 2-3 times a day.

Panasonic Eneloops are my go-to rechargeable batteries. The standard white ones and “pro” black ones have served me well for years. I wonder how they’d fare in this test.

Tyler, that "AA Battery" is a lithium-ion battery. It has a regulator to drop the Li-on 3.7 volts to 1.5 volts. When you tried to charge it with a nickel metal charger, you probably damaged that circuit, and possibly the battery itself. That type of battery runs at 1.5 until it can no longer provide 1.5 volts, then it shuts off. That's why it acted the way it did when you tried to use it to run the fan.

that is a crazy commitment to charge and drain those batteries every day! thank you for having the dedication to make all these projects into interesting fun videos :) I’ll be looking forward to the follow up video!

You should definitely re-run the capacity test and record the results every month or so throughout the year if you didn't already plan to. also, could be interesting to see which batteries get the warmest when fast charging and in use

I noticed you didn't use Eneloop a Panasonic brand. I've used the same set of 8 batteries for about 10 years or maybe more and they're still decent batteries for wireless gaming controllers.

I can't believe you didn't include Eneloop batteries. Best rechargable battery hands down. Eneloop has 2000 mAh. My oldest Eneloop batteries have lasted over 10 years so far. They still have over 60% life, which is leagues better than most rechargeables. So for longevity Eneloop might be the best, but I haven't read reviews of other batteries.

5:40 the usb recharge battery is a lithium battery with a buck converter to drop it to constant 1.5v. when the internal lithium 3.7v battery "dies" gets below it's minimum voltage cutoff the buck converter just shuts off the output.

[Elminator]

Good work. I'm surprised you didn't try Eneloop or Eneloop Pro by Panasonic.

I bought 16 Tenergy 2800 mAh AA batteries (and eight AAA Tenergys) and the Tenergy eight bay battery charger from Amazon. And as a ham radio operator that has insane experience with Nickel-Metal Hydrides for 30 years, they are the best ones I've ever had by far. You can leave them in a radio or whatever or leave them on a shelf and they hold their charge so much better than any I have ever owned.

I can tell you what was happening to him at 1:50, he was trying to sneeze. He was trying to use looking at light to force a sneeze cause his nose was tingling. He may have photic sneeze reflex like I do, which means heavy eye stimulation triggers sneezing. It's actually quite useful when you feel the need to sneeze.

When I clicked on this video I was expecting a topic on which rechargeable battery is the best, however I walked away with vast knowledge on the finite universe in which we reside. Truly peak performance, what others see as a grain of sand in a desert on this YouTube platform, I see all the atoms and molecules which reside in said grain. Thank you for blessing us with this. Also tiddy.

Thanks for taking the time to do this. Well documented testing and research. Really helped me make a decision on which rechargable to buy.

Draining and recharging the batteries once a day is a hell of a commitment to make! Glad to see you're so dedicated to this!

[WhateversClever]

Excellent test. I just bought a 24 pack of Amazon rechargeable aa’s and a 24 pack of rechargeable aaa’s. Came here to justify my purchase and now I feel even better about it, thanks

[bigharrybushcraft]

To promote battery lifespan and reduce the risk of handheld napalm fans, rechargeable batteries have battery management systems (BMS). These are what control the charge/discharge rates and levels of the units. That is why the fans just shut off at a certain level instead of fading out. It is also why the operational maths aren't necessarily a direct reflection of mAh. Great job! I appreciate you informing me that I bought crap batteries. :)

[rustyshackleford]

What kind of rechargable battery test doesnt include panasonic eneloop batteries, but includes dee lee pow?

[EspadaMK]

Lower capacity batteries are often longer lasting in terms of cycles so are useful in some situations like TV remotes.
