Checking some old 18650 to see how badly they have degraded ..

Very interesting. Thanks old!

About 2 year old AW2600 ... 1A discharge = 2415mAh ... Thats not bad at all ...

Thanks for the results!

Impressive AW2600. Have you used it often?

I got the AW to compare to , so its had a very easy life , had no use but testing ..

Ohh, I see.

Have you kept it in a cold place, fridge?

Thanks for testing them old4570, I pretty much had the same results with my Ultrafire 3000's they where around 2200 when new and only a year later they where down to about 1500. They only had about 4-5 cycles on them and where stored at 3.7-3.8v.

I have herd quite a few people complain about the same thing with the Chinese based cells. It's going to be interesting to see how the Hi-Max holds up.

Would storage in the fridge be a wise idea?

If i don't use the flashlights for a while should i turn them on until the batteries are discharged to around 40% and then get them out?

greetings!

No , toolbox in my room ... same as all the other cells

If you wanted too .... Just dont freeze them

Hmmm , is that Wow 18650 almost a year old ? ... Just checked , the Wow should be more than 12 months old maybe 18months ??

Will have to find some time to discharge it ...

my 3yr old AW2200 is still at 4.1volt discharge so i dont know how many mAh it still has left..

it's interesting seeing the long term results of these batteries. However since they've been through different usage patterns it's hard to compare them definitively. The main thing I gather from your data, is that out of the AW and eagletac 18650 (both of which have had little useage), the AW has performed better.

Some of the data from cpf, also suggest that the older AW perform better than older ultrafire li-ions.

I would love to see how the WOW has held up.

As far as I know they are a Chinese based cell. I opened one up and found no markings. I also tried shorting one out and it got to about 160F but never leaked.

Thanks , need to discharge the WOW18650 ...

What charger do you use to do the discharge test OLD4570? Thanks!

The cheap old Imax B6

Do you know what charger I should buy? I want to get one to test the capacities of my old 18650.

2454mAh Capacity for my WOW18650 @ 1A discharge ,,

What hobby charger to get ? For discharging up to 1A , the Imax B6 is fine + Cheap as chips on Ebay ..

If you wish to discharge up to 5A [ Amp ] , price entry point is about $70 something Dollars .

Updated with some more cells tested today ...

Updated with Fireworm 3000 result , discharged @ 1A
