What should be the life of a battery? - e-cigarette-forum.com • The place for electronic cigarette reviews, news and chat

If I am using my two batteries alternately each day when should I expect to buy replacements?

I should have said that I am using a mini but I would be interested in the same answer for the super mini

There are lots of variables here. How often do you vape and for how long? Do you drip the atomiser? With a mini you'll be doing well to get 4 hrs out of a battery - it will fade, too, so it will be much harder to use towards the end of that time.

How long do you think it will be before I need to buy a new battery

That's always hard to say. Does the person you bought from offer a guarantee on batteries? How long is it?

The main reason that it is hard to say is that the batteries on generics do seem to vary wildly in quality from one batch to the next. The best rule of thumb is to always have a couple of spares.

Not as a replacement but a spare.

I would say now.

Always a good idea to have a back up.

just for info and has no real world comparison values due to the nature of these batts but when i was exclusively using my 901 and cycling my 2 batteries i needed to replace them after 6-8 weeks if i remember rightly. so one battery would have lasted me 3 to 4 weeks before useage time was too far reduced per charge.

Sailebao, the maker of the SLB battery (found on the DSE901's) quotes:

"Content of battery: 180mAh
Normal working voltage: 3.2V-4.2V
Full battery can keep for: 190-200 puffs
Charge time: 2-2.5 hours
Life of battery: 200 times charger"

So by my calculations - if you keep 2 batteries in rotation and rotate 4 times per day, each would be charged 28 times over a 7 day period.

200 charges would be reached within 7-8 weeks.

That sounds about right to me.

But usually batteries are rated in half lifes. So 200 charge cycles (full charge cycles... if you tend to recharge early, you'll get more cycles) would decrease battery life by about half. It is a sort of limited decay though... I think you can stay at or around the half-capacity for a while, if you are willing to live with the limited amount of charge.

Yes, what vape4life said. I don't know about the specific electronics in e-cig batteries, but at least with the lithium battery cells themselves what you'll see is gradual decay over time, not sudden expiry. You can typically see this in old laptops that, when the batteries were fresh, gave a good two hours of battery life, only to be reduced to about half an hour eventually. But the thing is they can keep giving you that half hour for a very long time. Depending somewhat on the electronics of your e-cig battery, you can expect the same sort of behaviour.

Also, what Keef said. Since you know you're going to need a new battery eventually, might as well get it sooner rather than later.
