3.66V under load - weak performance.

[ian-field]

Recently my DIY coils (Evod1)haven't been as good as I know I can do, Tried a new genuine part atomiser - worked OK (ish) for a while and then tailed off. An old Vivi-nova V2 that I know works also didn't do much, so I tried another battery which seems to be OK.

The battery was showing 3.66V under load terminal voltage - which I thought should be OK?

The battery is getting on for 3 years old, but the under load voltage says it shouldn't be causing a problem!

How are you testing under load?

batteries develop internal resistance with age/use. Sounds like time to replace your cell.

What batteries are you using and what is the resistance of the atomizer?

Batteries are usually good for about 300 charges or so give or take. Should replace every 6 mos to year depending on your usage.

I agree they are generally good for about 200-300 full charge/discharge cycles depending on how hard we are on them. But I rarely let mine get close to fully discharged and I don't push them too hard. I'm using some that are over three years old now and they are still performing quite well.

IMO replacing after a year max isn't necessary. Unless they are worn out ... but that depends on usage only.

I rotate between two batteries using one battery per day. So, in a year, each battery is used so pretty much until it's dead for 180ish days a year. I toss at Christmas time. I do major mod, drip tip, and topper cleaning at Christmas and June 6th (D-Day).

Just a routine that seems to work.
