AA Lithium Rechargeable Comparison: Jugee, Bonai, Amptorrent, EBL, Tenavolts, Gigastone, Deleepow

Subscribed because I enjoyed your dry humor. One of the best reviews I have watched on YouTube.

Your datasheet is simply fantastic. Thank you.

Scott, you are incorrect about the Jugee's, they only maintain 1.5v constant until they are drained to a certain level (Possibly 2/3rds of capacity), then they switch to 1.2v to simulate or trigger low power warning for some devices, basically they are designed to to drop, not run 1.5v constant then shut down like others do, I have been using a few different brands of these lithium AA's and the only ones I have that will trigger a low power warning before they fully runout are the Jugee's, all the others shutoff without warning, so they may not give you the full rated power, but they certainly work better in simulating a 1.5v disposable battery and they have lasted longer than the other ones I purchased, mainly the Kentli, which all died after less than 20 power cycles.

Thanks for the review! My first foray into lithium rechargeable AA cells was the Epoch brand, that each have a micro-USB socket. Each 4-pack comes with a half-octopus cable that plugs into a USB A socket on one end, and each cell's micro-USB socket at the other. In practice this is less fun than going to the dentist, so I never use them. We'll see if the Gigastone charger fixes that. Gigastone sounds like a CPU benchmark form 20 years ago.

just the timelapse at the end deserves a like

Great video brother i appreciate the test 👏. I recently bought EBL disposable lithiums to try in my 🔦 flashlights and trail cameras but never thought about rechargeable lithiums!! Thanks again buddy

Thank you for recommending batteries for us Juggalos, an underepresented group in YouTube review videos.

The old EBL NiMH 2800mah used to have some of the highest capacity for NiMH when new, but they tanked quickly over time. Cool video

Perfect! This saved me from a huge mistake! I thought Lithium would simplify my life by not needing to swap out batteries as much in devices... but now I am seeing that this adds the complication of different chargers for different batteries, and wildly inconsistent performance and specs. Think I'll stick with good old-fashioned NiMH batteries for now, the last set lasted me nearly 7 years before they started being problematic, so moving to lithium is probably just wasting money unless I have portable devices that really need the extra power.

Awesome. Halarious at times. Well done.

Did you actually see at what point of the life cycle the Jugee’s dropped in voltage? From my understanding this is only supposed to happen when they have reached a low overall remaining charge, and the voltage drop is actually intentional in order to trigger low battery indicators on devices that watch for low voltage to indicate low remaining charge. These are quite popular in the Gameboy modding scene for that exact reason and some pretty involved members of the community have worked directly with Jugee to try to work out ideal voltage for this purpose. They have actually changed the indicating voltage based on user feedback. I’ve yet to take the plunge on any lithium ion AA’s so I’m curious what your testing showed on this feature. If it’s truly triggering at ~50% capacity, that’s definitely a problem.

I love your work, sir. I subscribed for more content like this.

Excellent video. Just one comment. The load tests should be done with a much lower current. Say 10 mA, 100 mA , 500 mA and maybe 1 A.

Great video :) Voltage sag under heavy load is quite typical for voltage regulators as they self-protect from current and thermal overload. The voltage regulators in these cells are tiny and i doubt they are rated much more than 1A. A tare-down would be interesting. We have all had at some point a finicky remote, gizmo or toy which really only works well with fresh alkalines and these applications are where i hope these lithium ion AA cells could really shine. It would have been really interesting to see voltage under much lower loads - 50mA, 100mA, 250mA, etc - i hope it would have been closer to 1.5v.

Love your no BS attitude. Don't change it. I've been trying out the AmpTorrent for a while and so far it's about the best substitute for an alkaline AA at least in my use case. I use it for my Omron blood pressure cup all the way through using it for LED candles which run about 4 hours per night. In addition, I found that it had good compatibility in some of my granddaughters toys. I hated the thought of sticking USB dongles into the side of my batteries. However, I'd like to see a standardization and ideally a company like Amazon selling their version of lithium rechargeable batteries. More to do with trust and replacement than anything else.

Great review. Thanks.

Super informative !

Good video. Thanks for explaining the test setup. Have you seen XTAR batteries? I have use their chargers to test 18650 cells for capacity. I did notice a review showing the XTAR cells have RFI (radio interference) which is bad news. I use a lot of batteries around my radios so I keep looking. Oh did you test the batteries or cells here for RFI?

hi, is possible to charge one brand Li Ion 1,5V baterie with another brand charger? thx

What I'd like to know is how they perform at very low discharge - like a smoke detector. That would take a long time to get results but it would be worth it. NiMH, even the LSD eneloops suffer from voltage drops over time. How do these perform compared to disposable Lithium AA?
