18650 6000mah

Recommended Posts

I bought some 18650 Li-ion batries and they say 6000mAH on them. If I'm reading this converter right that's 6AH? Is that right? I'm trying to use 2 of the 18650's to run d380's. If 2 of these are 12000mAH and that equals 12AH....that's alot more than the 4.5AH 6v sealed lead acid rechargable I'm using now. Is that correct?

 

I put 2 diodes on it and got the voltage down to around 6.4 - 6.5v, cams seem to work fine, just wondering how long they will last

 

Thanks a ton for any info!

Yes it is 6Ah

Be very wary of any Lithium Ion batteries with capacities over 3500mah. There is a lot of fake ones out there with inflated capacities.

Yes the 380 will work fine up to at least 7V. As Bill stated about the very best you will see with 18650 is about 3500mah. I have some that run 3200-3400mah and they do quite well. On a P32 I have gotten 700 pictures on just one battery.

Honestly, in my experience, those fake mah rating 18650's are a waste of money. The actual capacity is probably less than a AA rechargeable, but they slap a ridiculous 6000mah label just so people will buy them. You're much better off sticking with a name brand cell like Panasonic or Olight if you want the best performance. If an 18650 cell is advertised with a capacity higher than 3600mah, you should avoid them or at the very least be aware the capacity rating is false.

Those look just like the ones I'm getting out of laptop batteries. Flat on both ends with vent holes on the positive end. Hard to use them in a flashlight, they don't make a consistent connection

You can use a small magnet to convert a flat top into a "button cell": http://www.ebay.com/itm/6-magnets-to-conve...HkAAOSw44BYUNLc

Just recently bought some 5000mah batteries and I did some discharge/charge cycles to get mah ratings, and they were around 500mah. I would expect the same results with yours. If they seem light, they are junk.
