Tritium Battery "COULD" power your phone/tablet for 20 Years at US$1,122 it`s not cheap

But you know what happens when you buy a battery from an Chinese website an 20amp battery is really a 2amp battery, and the rest of the weight is a bag of beach sand.

John.

 

That sounds like a really bad idea.

And Chinese batteries tend to explode AND be underpowered lol.

 

Yeah, and next time you drop your phone down the toilet, you take out half the city

The ironic part is half the world's batteries ARE made in China. /facepalm

 

I try to get Japanese batteries but yeah I know.

 

Official manufacture battery`s from china are fine, as the manufacture does quality control, It`s the fake or non-brand battery`s you have to worry about,but sometimes it`s virtually impossible to tell the difference, did you get a really great bargain or a fake, you can only be certain of an genuine battery by ordering one from the manufacture, or trusted resellers.

Eneloop nimh battery`s are the best you can buy, but some are now being made in china not japan, and tests of the Chinese eneloops show that they are of a lower quality than the ones made in Japan, So ask the seller to check were it says the eneloops are made on the back of the packets if you want the best quality.

I'd get rechargeable lithium ion batteries over NiMH personally. The memory effect is a real pain.

 

You can buy the empty battery banks on ebay, then you can add your own 18650 li-ion cells, that are in the majority of removable notebook battery`s and you can remove them from faulty notebook battery`s a lot of the cells will still be ok, you have to be careful though as the bare 18650 li-ion battery are unprotected and can be quite dangerous if you dont know what you are doing.

Is this some kind of October fool joke? While this thing does exist, what kind of fun will you have on your phone with 16.2 microWatts?

 

Replaced the six 18650s in W230SS's pack today:

Spoiler: battery pack, old and new cells

However, you can be certain all of the old ones (purple) are pretty worn, though not failed; seen a year of use. They're all linked together in 2x3 series, so at best one may be a wee bit better than the other, but consider them ~25% of new nonetheless. And yes; take care when charging and any usage where draw is unlimited; no overvoltage or -current protection (pack's pcb takes care of that). Both batches ' Made in Japan', and that shows:

Spoiler: Samsung ICR18650-28A vs. Panasonic NCR18650B

Panasonic's going to make the actual batteries in Tesla's new mega-factory. Not coincidentally; Sanyo and Eneloop are owned by Panasonic.

Side-note; replacing after a year is a bit wasteful. Problem is that Clevo didn't have battery care software until the recent models. It'd be preferable to keep charge at 70%, instead of 100% all the time. Still ... each is $8, so $50/year for new batteries isn't that bad; new pack is $75 and has 20% less capacity (uses the 2800 mAh Samsung cells).

 

Speaking of replacing battery packs, does anyone know how the system will respond if one makes a customized battery pack with more cells, say 3x3 or 4x3 for this Clevo?

 

I bought the same Panasonic 18650 3400mah li-ion cells for usb battery box, but i got the protected version.

John.

 

It'll do fine as long as you match voltage (x in series); system doesn't care because it doesn't actually know the capacity of the cells. If it did, there'd be no need for recalibration.

What happens is that it'll supply a certain voltage and keeps doing so until the cell's internal resistance increases due to the higher charge level. To overcome the additional resistance, the pack will keep stepping up voltage until it reaches ~4.2V, which is considered 'full'. At that point it'll taper-off charging (part of the protection circuit). With one or two extra cells in parallel it'll simply take longer for the sets to increase resistance and, thus, voltage; charge time will be proportionally longer. Of course, you are also increasing max. ampere capability. But that is the same as with an adapter; potential is there, but won't be used unless required by the system.

The mAh/Wh report you'll see in HWiNFO or other tools will be wrong, though. That information is part of the battery pack's id. Interesting, come to think of it; that's firmware stuff, so ... stored on a writeable eeprom. Flash ' 70% charge option' bbios, install battery software and we're good?

Nice. Tesla has about 7,000 of them, but not as good as these cells; it uses 'merely' the 3,100 mAh variety.

For a laptop replacement or upgrade pack you want unprotected, though; the 2mm for the protection circuit makes them too long to fit inside most casings. Can always remove the 2mm coin-sized pcb if necessary; they're added to unprotected cells post-production.

 

I have spent over 10 years on a flashlight website CPF and we use li-ion cylindrical cells all the time, I prefer the 18650, I have more than a dozen flashlights that use the 18650 cells, though i prefer the protected version for safety.

Oh ya Panasonic batteries were by far vastly superior to Sanyo, Sony batteries. Heck I had an old T60 with a Panasonic 6 cell, still worked and held most of its WHr after many years.

 

I believe in "still worked", but most of the WHr? Are you really sure?
