18650 Storage

>>1157371
Store them about half charged; full charge stresses the anode more. Fridge is good-- it will slow down the chemical/mechanical processes that age the battery.

that will be fine for ~ 6 months, but you can't store them for eg 10 years that way.

Thanks, do you have any reference or paper I could look into ?

do not store your batteries in the refrigerator or freezer... look up J Mooch Muchow on youtube or facebook. he will answer any questions you have... his word is second to none

substandard.

not a vaper, I'm thinking of using them to diy powerbank since all the ones that I got have fake "5000 mAh ultrafire" batteries.
Also planning on replacing my laptop batteries with these.

>Not storing your lithium batteries fully charged in a tool box with a variety of loose bolts, copper shards, lead weights and a geological hammer
>Not violently shaking said tool box every so often to remind yourself of the fragility of existence

Save your old laptop cells. Can test them and / diy.

>>1158068
Not building a power pack, bms, and 3 stage charger with them?

Not charge to 80% and always have juice for ohone and bluetooth or radio? / drawer lights?

>what is ziplock bag
>>1158072
I will, however my laptop isn't staying on for more than 30 mins of web browsing.

so that's what, like $10 of battery? it's not worth worrying about this much, throw them in the fucking garbage

>>1158683
I get it. U likely have 1 shitty cell and 7 more great for projects

>>1158689
Good panasonic cells like tesla uses are ~$3 or less each.

8 for a laptop would be well under 25 bux.

But most of /diy is poorfags or kids who have little money.

Innneficeint wast of time but $3 to replace 1 bad cell could double anons work time. And iff he builds a pack to velcro to his laptop and charges over night he can shitpost indefinitely

Put them to "storage charge" which is around 3.85V. Then charge them at a dry and cool place. Put them in a zip lock bag or a closed glass jar with one of these little silica packs that are found in boxes for shoes or electronic stuff. A fridge is a good idea, deep-freezing not so much. Let warm to ambient before taking out of the bag/jar.

Sorry, I meant "store".

Tell me where 18650 can be gotten for $3 each.

https://eu.nkon.nl is good site to get cheap 18650 (legit ones, not chinese rebrandings), only thing is you have to pay shipping which is about 20% i think

If you buy laptop batterys in bulk you can get as low as 1$ per cell, but you have to watch on pages like ebay

Get a charger with storage function, which will bring the batteries to 3.7V, and store them in a lipo saver bag, they'll last for 1 year before degrading.
