In order to clarify: We do not measure the capacity of the batteries in hours but in puffs.
With puffs we do not mean 10 or 15 second puffs
, but 3 second puffs max 
3 seconds is he average of a normal puff (We know heavy smokers will suck longer on the device, but that is not what we can consider an average).
DURA or DURA-C or JOYE510 batteries for that matter can/should function 200 to 250 NORMAL puffs max!
The batteries can have 200 times charging and use.
After more then 200 charges and usage, you will get lesser puffs out of them.
NOTE:
We brought to you the DURA-C, you are in control, but please take it easy and adapt to a new way of vaping by not pushing the manual button for too long! Read a customer quote below which explains a lot...
Jeff, after taking it cautiously for a little while, I gradually increased use and I have now adjusted my "draw" to coincide with the manual switch performance.
This is great, as the carts are wonderful and last a lot longer than 901 or pen carts for me, before having to top off.
